Over the last year Poole Harbour has become a hotspot for White-tailed Eagle activity. The vast natural harbour provides rich forging opportunities throughout the year with abundant supplies of fish, including Grey Mullet, as well as waterbirds, and many quiet areas to perch. We have been particularly encouraged that three-year-olds G463 and G466 have become established as a pair, and up to six other birds have been regular visitors over the past twelve months. Here is a brief overview of each of the birds, and also where best to see them, by Tim Mackrill.

G463 and G466

Male G463 was originally translocated to the Isle of Wight from Sutherland in North-West Scotland in 2020. After spending his first winter near Chard in Somerset, G463 crossed the English Channel in early April 2021 and spent seven months exploring Netherlands, Germany and Denmark, favouring many areas with expanding White-tailed Eagle populations. G463 made the return journey across the English Channel in November that year and then spent the majority of the winter in East Anglia, favouring parts of North and West Norfolk and also the Suffolk Coast. During his time in Norfolk, G463 lost the lower part of his right leg, as reported in our blog in January. Despite this, G463 appears to have adapted well, and again crossed the Channel in early April before summering in mainland Europe; returning to many of the sites he had first visited the previous year, and also making a short flight into southern Sweden. 

Despite the fact that he would have encountered many White-tailed Eagles during his travels in mainland Europe, the draw of returning to the South Coast clearly proved very strong and G463 headed back across the English Channel on 22^nd September last year.  He then spent time in favoured areas in East Anglia and Somerset, before finally returning to the Isle of Wight on 9^th January, after more than two years away. He first visited Poole Harbour on Boxing Day, and has been present there almost continuously since late January, when he first encountered G466. 

Female G466, was also translocated to the Isle of Wight in 2020, from a nest near Uig on the Isle of Skye. After spending her first winter on the Isle of Wight, G466 flew north to Scotland the following spring, and then spent the rest of the year in Caithness in Sutherland. She eventually returned to the Isle of Wight in February 2022, but then flew north again on 5^th April, and like G463, returned to many of the sites she had favoured the previous summer, including Cape Wrath, the most north-westerly point of mainland Britain. She flew south again in late September and after visiting various sites on the South Coast, she became a regular at Poole Harbour from 20^th November, appearing to displace another female, G801, who has been resident over summer 2022 (see below). 

G466 was joined by G463 on 20^th January, and the two birds have been together on an almost daily basis since. Their favoured area, which covers approximately 125km², is centred on the Wareham Channel at Poole Harbour, and stretches south to the coast at Kimmeridge, where the satellite data indicates they catch fish off-shore, and also Wareham Forest to the north. The birds have made regular courtship flights in recent months, flying in tandem across much of this area. It is clear that they are now a pair, and we are hopeful that they may try and breed as early as next spring. 

G801

Female G801 was translocated to the Isle of Wight in 2021 from the Isle of Lewis in the Outer Hebrides. She spent much of her first winter on the Isle of Wight, but also visited Hampshire and Dorset. As the days began to lengthen, she made longer exploratory flights into Surrey and Sussex during February and then west to Devon and Cornwall during March.  G801 returned east to Poole Harbour on 19^th March, and became a regular in the Wareham Channel during April. On 4th May she set off on another longer exploratory flight, heading east to Kent where she was seen at Sandwich Bay Bird Observatory. She then followed the East Anglian coast north before continuing through Lincolnshire and Yorkshire, reaching Saltburn-by-Sea on the Cleveland coast, on 9^th May. After a few days in the nearby North York Moors, she headed south again, stopping at Middleton Lakes near Tamworth from 15^th-23^rd May before returning to Poole Harbour on 27^thMay. 

G801 spent the rest of the summer at Poole, again favouring the Wareham Channel, where she was regularly seen from the Birds of Poole Harbour’s excellent boat trips. She also visited the coast at Kimmeridge. However once G466 became resident at Poole Harbour, as described above, she seems to displace the younger female, who moved to Cranborne Chase, another area that is favoured by the young eagles. Nevertheless, G801 continues to make regular visits to Poole Harbour, most recently on 21^st May. 

G812 and G486

Male G812 was translocated from the Isle of Lewis in 2021.  He has remained in southern England since release, favouring an area that extends from Poole Harbour in the south to Cranborne Chase in the north. He has formed a close association with female G486 who was translocated from the Isle of Mull the same year. The female has been more nomadic, visiting East Anglia during July 2022, Colliford Lake on Bodmin Moor in Cornwall from 11^th December – 26^th January, and then various South Devon estuaries in late January and early February this year. She returned to her favoured areas in North Dorset on 9^th February and she and G812 continue to visit Poole Harbour, often together. 

G816

Another 2021 male, G816, who was translocated from the Isle of Lewis, has also remained in southern England since release. He is a regular visitor to Poole Harbour, and also spends time on the Purbeck coast at Kimmeridge, the Isle of Wight, in south Wiltshire and Cranborne Chase. During the early part of 2023 he began to associate with 2021 female G818, but the female, who was also translocated from the Isle of Lewis, has since flown north to the Cairngorms, where she spent much of summer 2022.  

G318 

Female G318 is one of three surviving birds from the first release in 2019. She remains unpaired and somewhat nomadic, but was a regular visitor to Poole Harbour in 2022 when wandering away from her favoured areas in Cranborne Chase and the Avon Valley. She has spent the past two summers in the Peak District and recently returned north to the same favoured area near Howden Reservoir on 24^th May.  

Where to view White-tailed Eagles at Poole Harbour?

White-tailed Eagles can be encountered just about anywhere in and around Poole Harbour but there are a few particularly good spots to try:

• The new Ham Common Viewpoint offers panoramic views along the Wareham Channel and the areas often favoured by G463 and G466. More details here: https://bcpprojects.net/ham-common-lookout/
• Arne RSPB reserve offers an excellent chance of seeing White-tailed Eagles, with the Hyde’s Heath trail and Coombe Heath viewpoint the best places to try. 
• Birds of Poole Harbour run boat trips throughout the summer, and often get excellent views of White-tailed Eagles from on board. For more details check out the Birds of Poole harbour website: https://www.birdsofpooleharbourbookings.co.uk/.  

Fantastic that Poole Harbour’s now-resident White-tailed Eagle G801 flew directly over our @harbourbirds boat this morning. Fair to say everyone was very excited, including @jsparker_ and @LivCooper23! pic.twitter.com/q1lB0Cw4gz

Thank you

Sincere thanks to everyone who has been in touch to report sightings or sent photos of eagles either from Poole Harbour or in their local area. This information is of real value and adds to our understanding of how the birds are living in the landscape. You can report any sightings using our online form. We have been thrilled at the excitement the birds have generated, and greatly appreciate the support the project has received.  

Very many thanks to everyone who has made donations to the Foundation and the White-tailed Eagle project in the past few months. Your support is greatly appreciated. If you would like to donate to our work, then you can do so via the link below.

We are now in the fourth year of the project we run in partnership with Forestry England to reintroduce White-tailed Eagles to southern England, through the translocation of Scottish chicks to the Isle of Wight. Early signs have been encouraging with two pairs forming, and other young eagles learning to live successfully in the English landscape. 

Early pair bonding 

Two of the birds released in 2019, male G274 and female G324, are now well-established as a pair on the Isle of Wight, as project officer Steve Egerton-Read described in his latest Forestry England blog. Steve has dedicated a huge amount of time to monitoring the birds in the field and this has provided an extremely valuable insight into their daily foraging habits and diet. We have been particularly encouraged that they have been catching fish around the coasts of the Isle of Wight throughout the year, and that they readily catch cuttlefish in the seagrass beds of the Solent. This rich local food supply will be extremely valuable when the first pairs begin breeding. Elsewhere a second pair have become established in West Sussex. Male G471 and female G405, both released in 2020, have been favouring the Arun valley and surrounding areas, and the male also makes regular trips to the coast. 

We have also been extremely encouraged that one of the 2021 females, G801, has taken up almost permanent residence at Poole Harbour since her arrival there, in early March. Recently G801 has been joined by two different males: G816, who has been summering in Wiltshire, and G812 who spent much of the winter and spring in north Dorset. The proximity of Poole Harbour to the Isle of Wight, coupled with the rich food supply, including fish such as Grey Mullet and Bass, make this another potential early breeding site. Although most White-tailed Eagles do not breed until they are five years old, the satellite data demonstrates that pairs can form much earlier, and we are hopeful that one of these visiting males will settle at Poole Harbour with G801. 

Returning to favoured sites 

Some of the younger birds dispersed widely in the spring and five individuals are currently in northern Scotland. 2021 females G818 and G487 are in the Cairngorms and two other females released last summer, have been spending time further north. G542 is currently in Caithness and G547 is living around Cape Wrath and other locations on the Sutherland coast. The fifth bird is 2020 female G466 who has returned to northern Scotland for a second summer. She spent much of 2021 in Caithness and Sutherland before flying south in February this year and then spending two months back on the Isle of Wight. She headed north again in mid-April and is now back in the Caithness having spent much of the past few weeks in and around Cape Wrath. The map below shows her 2021 (yellow) and 2022 movements (white). 

Another bird that has returned to an area that it visited last spring, is G463. This male released in 2020 crossed the English Channel in April 2021 and remained in mainland Europe until November, favouring the Wadden Sea coasts of the Netherlands, Germany and Denmark. He visited several locations in southern England during the winter, before spending the early part of the spring in East Anglia, returning to sites he first visited 12 months earlier. Then on 3^rd April he crossed the English Channel in the same location as 2021, but three days earlier. He has since returned to many of the sites he visited in 2021, with one notable exception: a short excursion to southern Sweden between 28^th April and 1^st May. The map below shows how faithful G463 has been to sites he first visited last year (2021 = yellow, 2022 = white). He is currently heading south-west through Germany, and so may return to the areas she previously visited in the Netherlands, or perhaps return across the English Channel once again. 

Like the two 2020 birds, G318 has also returned to a previous haunt. The 2019 female wintered in Dorset, but then flew north to the Peak District on 16^th May and has returned to the moors in the Dark Peak that she frequented for more than two months last summer. This bird has been a lagomorph specialist since release and it seems that Mountain Hares could be the reason she has returned to this particular area. 

The fact that three birds have returned to sites that they first encountered on their initial explorations, illustrates the superb navigational capacity of the young eagles, and the value of the initial wanderings and the associated knowledge they assimilate about the landscape.  

2022 translocation cancelled 

During June we were intending to translocate the next cohort of chicks to the Isle of Wight. However, the worsening situation with Avian Influenza which has resulted in major mortality of breeding seabirds around eastern and northern coasts of the UK, and poses a considerable risk to White-tailed Eagles – which can contract the virus by eating infected carcasses – meant that we felt the most responsible approach was to not translocate any chicks this year, particularly as fieldwork indicates it is a poor breeding year for White-tailed Eagles. We have informed NatureScot and Natural England of this decision, and hope to extend the licence to account for the missed year. The original licence permits us to release a total of 60 White-tailed Eagles over the course of five years with the aim of establishing an initial population of six to eight breeding pairs on the Isle of Wight and surrounding areas of the South Coast. 

In the meantime, we will continue to closely monitor the birds released in previous years, particularly in relation to their foraging behaviour, daily movements and how they are living in the landscape. We have also constructed two artificial nests to encourage early breeding behaviour.  

Thank you

Sincere thanks to everyone who has been in touch to report sightings or sent photos of eagles in their local area. This information is of real value and adds to our understanding of how the birds are living in the landscape. You can report any sightings using our online form. We have been thrilled at the excitement the birds have generated in different parts of the country, and greatly appreciate the support the project has received.  

Very many thanks to everyone who has made donations to the Foundation and the White-tailed Eagle project in the past few months. Your support is greatly appreciated. If you would like to donate to our work, then you can do so via the link below.

One of the most pleasing aspects of the first three years of the White-tailed Eagle project has been the great excitement of people who have seen one of the birds. The far-ranging exploratory flights of the young eagles has meant that they have been enjoyed by birders and wildlife enthusiasts across much of the UK. People often ask us to give the eagles’ daily locations on the website but we need to prevent disturbance to the eagles and local people. We have made many friends in the farming, forestry and landowner communities who have welcomed the great birds on their land.

Encouragingly, we are now seeing some of the older birds – those released in 2019 and 2020 – returning to the Isle of Wight and the wider South Coast region where we hope an initial breeding population will become established. On the Isle of Wight two eagles released in 2019, G274 and G324 have paired up, and, although still too young to breed, they are showing territorial behaviour. Meanwhile two of the 2020 cohort – male G471 who recently returned to the South Coast after an extended stay in southern Scotland, and female G405, who spent much of last year in South West England – are showing the first signs of forming a second pair, and have spent much of the past week in the South Downs in West Sussex, which is another potential breeding area.

Another bird that returned to the South Coast after spending a prolonged period away was G461. This male eagle, released on the Isle of Wight in 2020, explored widely along the South Coast during spring 2021 and then spent much of last summer in West Norfolk. After returning south in September, and being chased away from the Isle of Wight by G274, the young male began favouring Poole Harbour in Dorset. This huge natural harbour, with its abundant populations of a favoured prey species, the Grey Mullet, is a likely breeding site for White-tailed Eagles in the future.

G461 spent much of the autumn and early winter at Poole Harbour where many excited birdwatchers and members of the public were able to enjoy watching it.  On one occasion a boat full of school children enjoyed a fly past during a trip organised by the local charity Birds of Poole Harbour.

When not at Poole Harbour, G461 also visited the nearby Purbeck coastline, and spent time in North Dorset, in an area that has been visited by several other White-tailed Eagles since the project began.

Sadly, in late January the data from G461’s satellite tag gave us cause for concern, and we subsequently recovered the bird’s body in North Dorset on 27^th January, with Dorset Police and members of the RSPB Investigations team.

Post mortem and toxicology testing through the Wildlife Incident Investigation Scheme has subsequently identified brodifacoum poisoning as the cause of death. Brodifacoum is a highly toxic anticoagulant rodenticide that causes internal haemorrhaging. The bird’s liver contained approximately seven times the amount of brodifacoum required to kill a bird like a White-tailed Eagle. The satellite data indicates that the eagle, which was otherwise healthy, deteriorated and died over a period of several days.

Dorset police have today made a statement that no further police action will be taken.

Recent evidence indicates that brodifacoum poses a serious threat to birds of prey. It accumulates in the food chain and can cause secondary poisoning as a result. A number of cases where dead raptors have been found with very high levels of brodifacoum have suggested that it could also be illegally misused in some instances to target birds of prey. White-tailed Eagles are particularly at risk because carrion can form a significant part of the diet, especially of birds in their first year.  EU Environmental Risk Assessments have previously concluded that second generation anticoagulant rodenticides (SGARs) such as brodifacoum should not be permitted for external use because the environmental risk is too great. However, regulations around their use in outdoor settings in the UK have been relaxed in recent years, and we believe this could pose a significant risk to birds of prey and other wildlife.

It is very disappointing that G461 has become the latest bird of prey to die of brodifacoum poisoning, and we hope that the death of this bird serves as a reminder of the toxicity of anticoagulant rodenticide poisons and the impacts they can have on wider wildlife.

More encouragingly, two female White-tailed Eagles, G318 and G801 are the latest birds to take up residence at Poole Harbour, and there have been numerous sightings in recent weeks. With G463 back in England after spending five months in continental Europe last year, we are hopeful that the young male may eventually join the birds at Poole Harbour, particularly as G318, released in 2019, is now approaching breeding age. Since arriving back in England last November G463 has spent much of its time in East Anglia, but also returned to Chard area in Somerset – where it had spent its first winter – and visited Knepp in East Sussex last week.

Despite the loss of G461 we very much hope that White-tailed Eagles will become an increasingly familiar sight at Poole Harbour and in other parts of southern England, and that many more people will be able to enjoy seeing them in years to come.

It is now more than two years since we began the White-tailed Eagle reintroduction project on the Isle of Wight, in partnership with Forestry England. A total of 25 young eagles, all translocated from nests in Western Scotland, have now been released, including 12 this year. This year’s birds have yet to disperse away from the release site, but we have been monitoring the movements of the 2019 and 2020 cohorts closely throughout the summer via satellite tracking and field observations. 

The satellite tracking has provided a very detailed insight into how the young birds are learning to live in the landscape, and the extent to which they disperse and wander during their second calendar year, in particular. It has been noticeable over the past few months, how the behavour of the two age classes has varied. The 2019 birds have all gravitated back to the Isle of Wight, and with one exception, have remained local thereafter, whereas the 2020 birds are still in peak exploratory mode and are widely dispersed from northern Scotland, to the Netherlands. Here Tim Mackrill brings you up to date with their movements over the last few months. 

2020 birds

G405 

Earlier in the spring we reported that female G405 had made a return trip to southern Scotland, covering  2279 km (1416 miles) in four weeks. She returned to the Isle of Wight on 13^th April and has since spent all of her time in southern England, favouring three key areas: the Isle of Wight, Exmoor and Longleat in Wiltshire.

Following her return to the Isle of Wight on 13^th April, G405 headed north-west to Longleat the next day. She spent much of the next month favouring an area of some 20 km². This included the grounds of Longleat Safari Park, where she was seen taking carrion left out for the park’s wolves. She also made a two day return flight to south Devon on 17^th and 18^th April and three-day visit to the South Downs between 2^nd and 5^th May.

On 14^th May G405 headed west through Wiltshire and Somerset to Exmoor where she remained between 17^th May and 23^rd June. During this time she ranged over a core area of 85km², favouring several areas where rabbits are numerous. Significantly, she was observed with a second White-tailed Eagle on a number of occasions, and interestingly, this was not one of the Isle of Wight birds. We very much hope that as a breeding population becomes established in southern England it will encourage wandering young birds from continental Europe to stay and breed, and so it is encouraging that G405 was interacting with another young eagle in this way. 

After leaving Exmoor G405 spent another week near Longleat before heading back to the Isle of Wight on 2^ndJuly where she remained until 18^th July, spending most of her time in areas she had favoured during the winter, both inland and at the coast. She then crossed the Solent again and spent time in the South Downs before before completing a two day loop through Kent, and then skirting along the south side of London, passing over Dartford at 13:00 on 23^rd July before heading south through Surrey and into East Sussex north of Brighton.  She lingered around Ashcombe Bottom just north-west of Lewes until 3^rd August when she headed back west to Longleat and then Exmoor. She has remained in Exmoor since, favouring the same areas as before. A least one other eagle has been present during the same period.

G408 

G408 is the only member of the 2020 cohort to remain exclusively in southern England since release. With the exception of a two day return flight to the Quantock Hills in Somerset on 3^rd and 4^th April, G408 has been faithful to two main areas throughout the spring and summer: the Arun valley and a nearby area of the South Downs in West Sussex, and the Isle of Wight. The young male spent several weeks in the company of 2019 male, G393 in the Arun valley during the early spring, and has remained a regular visitor since, spending prolonged periods at Pulbrough Brooks RSPB Reserve and neighbouring Amberley Wildbrooks, as well as other locations along a five mile section of the valley. The satellite data shows that G408 was present in the Arun valley between 16^th April – 7^th May, 19^th May – 16^th June, 23^rd June – 22^nd July, 11^th – 22^nd August and 25^th-31^st August. He returned to the Isle of Wight during the intervening periods, favouring three main coastal locations where he was observed fishing, and also an inland area where rabbits are numerous. His visits to the Isle of Wight were often cut short by 2019 male G274 who became increasingly territorial during the spring and early summer, and chased the younger male across the Solent on a number of occasions. Like the other older birds, G408 also visited the release site once this year’s juveniles began flying.

Most recently G408 has spent time in the South Downs to the west of the Arun valley, where he was seen with G461 (see below).

G461 

During the spring G461 ranged extensively along the South Coast, wandering to Cornwall in the west and Kent in the east. On 22^nd April the young male headed north from Kent, crossing the Thames just to the east of Greenwich before continuing north through Essex and Cambridgeshire to North Norfolk. He lingered south-east of Holt for a week and then moved to West Norfolk. 

G461 then spent the majority of May on the south side of the Wash in Lincolnshire and West Norfolk, moving between Frampton Marsh RSPB reserve, the Wash NNR near Guy’s Head, the mouth of the Great Ouse near Kings Lynn and inland sites in West Norfolk, including the Norfolk Wildlife Trust reserve at Roydon Common, while also completing a two-day flight around the Lincolnshire Wolds on 16^th and 17^th May. 

On 29^th May G461 flew 150 km (93 miles) south-west, and was seen passing over Rutland Water before continuing through Leicestershire, Warwickshire and Gloucestershire and eventually roosting in the Cotswolds south-west of Cheltenham. He flew a further 80 km (50 miles) to the Mendip Hills in Somerset on 30^th, and 71 km (44 miles) to south-east Devon on 1^st June. He then spent time along the coast to the west of Lyme Regis, and inland near Axminster, before heading 70 km (44 miles) east to Poole Harbour on 8^th June and roosting on Brownsea Island that night. Next day G461 flew over Bournemouth and back to the Isle of Wight for the first time since 15^th April. 

Having returned to the Isle of Wight, G461 stayed for only three days before crossing the Solent again on 12th June and flying 102 km (64 miles) north to Berkshire. He lingered to the west of Reading for two days before travelling a further 206 km (128 miles) north through Oxfordshire, Northamptonshire, and Lincolnshire on 15th June, back to his favoured area on the south side of the Wash. 

Having arrived back on the Wash, G461 lingered in the area for the next 2.5 months, alternating between the same favoured areas as before. Interestingly G461 spent time in many of the same areas as 2019 male G393, who was present in West Norfolk and the Wash during the latter part of 2020. 

G461 finally headed south again on 6^th September, spending a night in rural Essex near Great Bardfield before continuing south over Greater London next day, passing over Hyde Park at an altitude of 450 metres at 17:08, and the over the London Wetland Centre soon afterwards. He roosted in farmland near the M25 at Cobham that evening before continuing south-west through Surrey and into the South Downs in West Sussex where he met up  with G408 on 12^th September. He subsequently returned to the Isle of Wight on 15th September.

G463 

As we reported in the spring, G463 was the first and, to date, only, of the Isle of Wight birds to cross the English Channel.  The young male made a 47 km (29 mile) crossing from Dungeness to Boulogne-Sur-Mer on 5^th April before heading north to Germany. He remained on the south side of the River Elbe until 18^th April when he continued north into Schleswig-Holstein, a stronghold for White-tailed Eagles in Germany. From there he slowly made his way along the Wadden Sea coast over subsequent days and, on 25^th April, crossed into Denmark. Three days later G461 was on the south side of Ringkøbing Fjord, which turned out to be the most northerly point of his explorations. 

G463 remained on the Danish coast until 29^th May and during this period favoured an area of the mainland coast adjacent to Rømø, the southern most of Denmark’s Wadden Sea islands.  Whilst here G463 frequented the mudflats, tidal channels and salthmarsh, but also spent time in wooded areas inland. 

G463 headed south back into Germany on 29^th May, returning to the River Elbe and then continuing south into the Netherlands and then Belgium. On 13^th June he crossed the border into France and that evening roosted in woodland just to the east of Boulogne-Sur-Mer, very close to where he made landfall after crossing the English Channel in April. He lingered in the area for the next few days and on 16^th was at the coast south of Ambleteuse. Had the winds been from the east it seems likely he would have attempted to return to England that day, but the wind turned to a relatively strong southerly, and this appeared to dissuade the young male from venturing out to sea. Instead he lingered inland and then on 20^th June headed back into Belgium and then the Netherlands. He flew 170km (106 miles) north-east through the Netherlands on 24^th June, passing over the Biesbosch where several pairs of White-tailed Eagles breed and eventually roosting in a forested area in the Hoge Veluwe National Park. Next day he travelled even further, covering an amazing 303 km (188 miles) back to the River Elbe in northern Germany, and again demonstrating how quickly young White-tailed Eagles learn the landscape. Next morning G463 crossed the Elbe and flew 51 km (32 miles) north to the estuary of the River Eider. 

G463 remained at the mouth of the Edier for the next month, usually roosting in woodland near Katinger Watt Nature Reserve and often perching on mudflats at the mouth of the Eider and also 15 km (9 miles) to the north. 

On 24^th July G463 headed further south into Lower Saxony, before moving west into the Netherlands, where he again favoured areas on the Wadden Sea coast, initially at Ijsselmeer (4^th-7^th August) , a closed off inland bay, and then Lauwersmeer National Park (10^th-16^th August) on the north coast. He then moved a little further east and, since, 21^st August has been frequenting the estuary of the Ems on the German border. It will be fascinating to see if and when the young male returns to England. He will have been encountering other young White-tailed Eagles throughout his travels, but the urge to return to the Isle of Wight is likely to prompt him back across the English Channel at some stage; although that may not be until next year.

G466

G466, a female, was the last of the 2020 cohort to leave the Isle of Wight in the spring, but quickly made up for lost time. She spent time in the South West and also East Anglia before heading north in mid-April. On 12^thApril she flew 228 km (142 miles) from the Suffolk coast to North Lincolnshire and then a further 163 km (101 miles) to County Durham next day. She continued north into Scotland on 14th and at 14:30 that afternoon reached the Firth of Forth, east of Edinburgh. She headed west along the south side of the Firth before flying over the west side of Edinburgh and then into Perth and Kinross. That night G466 roosted in a forested area near Glensherup Reservoir after a day’s flight of 255 km (158 miles). She again headed north on 15th April, flying 200km (124 miles) through the Cairngorms and then across the Black Isle before roosting to the north of Bonar Bridge close to the Dornoch Firth. She then made shorter movements of 32 km on 16th April, and 19 km on 17th April, before arriving at Loch Naver in Sutherland. 

The young female has remained in northern Scotland since, ranging widely in Caithness and Sutherland, but favouring two key areas. Her core area during April, May and June was a 24 km² area centred on Loch Naver, although she also made regular flights into Caithness, venturing as far as Loch Calder to the south of Thurso and Helmsdale on the east coast of Sutherland. On 1^st July she moved to the north-west and began favouring Cape Wrath, the most north-westerly point in Scotland, as well as a series of Lochs 10 km (6 miles) inland, including Loch Na Gainmhich. She also began visiting Loch Eriboll from 8^th August, extending her core range in the north-west to some 340 km². Like G463 in Europe, G466 will be encountering other White-tailed Eagles during her explorations, but we still expect her to head south at some stage. It will be very interesting to see when she does so.   

G471

After wintering near Bude in Cornwall, G471 headed north-east in early spring and spent time in north-west Norfolk and the Ouse Washes. Then, on 13^th and 14^th April the young male headed south-west, travelling 310 km (193 miles) to Herefordshire. Like G466, southerly winds encouraged G471 to fly north and on 15^th April he flew 276 km (172 miles) north through Shropshire, Cheshire and then Merseyside and the North West to the Yorkshire Dales. He subsequently flew a further 73 km (45 miles) to the northern Pennines on 16th, and then 56 km (35 miles) on 17th, passing Kielder Water en route to a roost site just south of the Scottish border. He continued onto Kelso on 18th and spent much of the day along the River Tweed, before moving to the northern end of the Lammermuir Hills in East Lothian the next day.

On 20th April G471 crossed the Firth of Forth west of North Berwick and then the Firth of Tay into Angus. He then headed west and eventually roosted in woodland near King’s Seat, 13 km north-east of Perth after a day’s flight of 130 km (81 miles). G471 continued north-east into the Grampian Mountains and then the southern part of the Cairngorms National Park on 21st April. He then turned south at 15:00 and roosted on the south side of Loch Tay after flying a further 161 km (100 miles). G471 continued south the next day, travelling 162 km (101 miles) back across the Firth of Forth into East Lothian, before roosting in the south- east of the Lammermuir Hills. He then crossed back into England on 23rd, before settling in the Cheviot Hills, having flown another 107 km (66 miles) south. 

G471 remained in the Cheviot Hills for the next fortnight, favouring various locations, including Catcleaugh Reservoir. He then headed north again on 11^th May and, other than a brief return to the Cheviots in early June, has spent the rest of the summer in southern Scotland, moving between various locations in the Southern Uplands. During this period he has favoured various water bodies in the area, including Hule Moss, Watch Water Reservoir and Hopes Reservoir, while also visiting the coast near Dunbar. Most recently, on 11^thSeptember, G471 flew back south to Northumberland.  

2019 birds

While the 2020 cohort are still in the peak of the dispersal phase, three of the four surviving birds from the 2019 releases are now very settled on the Isle of Wight and the wider Solent region. 

G274 and G324

Like G466 and G471, G324 spent the summer of her second calendar year in the Lammermuir Hills. She subsequently returned to the Isle of Wight in early September, and has been present ever since. During this period she has paired with 2019 male, G274, and the two birds have spent almost every day together since. It was notable that the two birds caught fish around the coasts of the Isle of Wight for much of last winter, and this preference for fish has continued through the spring and summer, with favoured species including Grey Mullet and Common Carp. Like last summer, G274 has again been seen catching Cuttlefish in the Solent, taking advantage of the seasonal abundance caused when Cuttlefish spawn in the seagrass beds off the coast of the Island. The two birds have also been seen catching Coot, gulls, corvids and injured or weak Canada Geese. They have also been observed stealing food from Marsh Harriers, Buzzards and even a Peregrine.      

It has also been highly encouraging to observe G274 and G324 exhibiting territorial behaviour throughout the summer. They rarely tolerate other White-tailed Eagles in their favoured coastal locations, and have been observed chasing other birds, most notably 2019 male G393, and 2020 male G408, on a number of occasions. Although White-tailed Eagles usually do not breed until they are four-five years old, the signs are certainly encouraging. Interestingly this territorial behaviour did not extend to this year’s translocated juveniles, and both G274 and G324 have been observed at the release site regularly since the first of the 2021 cohort began flying.

G393 

Like the 2020 cohort, G393 ranged widely during his second calendar year, before finally returning to the Isle of Wight in February this year, after 17 months away. Since his return G393 has remained much more local, spending the majority of his time in and around the Solent. Like G274 he has become proficient at catching fish, and has taken advantage of the abundant Grey Mullet in estuaries, while also predating gosling Greylag and Canada Geese, which are a key prey item of White-tailed Eagles in the Netherlands.  

Interestingly, in June, G393 flew north to one of the sites in Oxfordshire where he spent the majority of his first winter. He remained there for over a month between 15^th June and 17^th July before returning to a favoured location on the Solent. 

Like G274 and G324, G393 has spent prolonged periods at the release site with the 2021 juveniles. He appeared as soon as the first young birds were flying and was present for an initial week-long period before being seen off by G274. He then returned again on 28^th August, and remained until 3^rd September, which again coincided with another visit by G274 to the release site. The satellite data clearly demonstrates that the two males have become territorial and that G274 appears dominant over his compatriot from 2019. Nevertheless the time G393 spent at the release site should have provided plenty of stimulation for him. Seeing newly fledged juveniles, especially as they often directed food-begging calls towards him, will have been a valuable experience for G393.

G318

Unlike the other 2019 birds, G318, a female, has remained rather nomadic over the summer. After returning to the Isle of Wight for the first time in almost a year during March, she ranged widely in Dorset, Wiltshire and Hampshire. She spent time with G393 on several occasions during April, but unlike G274 and G324 has not formed a bond with the male; potentially because the two birds shared a pen together, and thus consider each other siblings. Despite a few visits to the Solent shoreline and another excursion to the Isle of Wight, she continued to favour inland areas where rabbits were her main prey item.

G318 continued to range between south Wiltshire and the Isle of Wight until 23rd April, when she made a 256 km (159 mile) flight to North Wales. That night she roosted in woodland 4.5 km south-west of Mold. Next day she continued to the north coast near Prestatyn before heading west, and then south, into Snowdonia. She passed to the east of Snowdon before settling in a large plantation to the north of Llyn Tryweryn after a day’s flight of 113km. She remained in the local area all day on 25th April, and roosted in the same location that night.

On 26^th April she headed east to western Staffordshire where she remained for two days before crossing into Derbyshire on 29^th and then north Nottinghamshire on 30^th.  Later that day she arrived in the northern part of the Lincolnshire Wolds; an area she had frequented during the winter. 

G318 remained in the Lincolnshire Wolds until 9^th May when she headed across the Humber and then north over Hull. Two days later she was back in the northern part of the North York Moors; again an area she knew from previous explorations. In fact, she returned to exactly the same locations as spring 2020. She remained in the North York Moors for over a month, again favouring areas where rabbits are common, before flying 142 km (88 miles) south to the Lincolnshire Wolds on 15^th June. She lingered in the Wolds until 23^rd June and then flew 232 km (144 miles) south through Lincolnshire, Northamptonshire, Buckinghamshire and Oxfordshire before roosting just north of Newbury. She remained in the same area all day on 24^th before continuing south on 25^th and returning to favoured haunts in north Dorset and Wiltshire, where she remained until 8^th July.  

On 8^th July G318 was on the move again, flying north through Wiltshire, before skirting around the east side of Swindon and continuing north into Gloucestershire the next day. She then spent three days around woodland in north-east Gloucestershire near Longborough, before flying 154 km (96 miles) north through the West Midlands on 18^th July. That night she roosted in eastern Staffordshire, before continuing north through the Peak District the next day. She subsequently settled close to the Upper Derwent Valley, living in an area of approximately 8km² for almost two months.

The latest satellite data indicates that she has now begun moving south again, and so it will be interesting to see if she heads back to the Isle of Wight, or continues her nomadic existence for a while longer.

 It has been a very encouraging few months for the project, and it will be fascinating to see how events unfold this autumn. Last year’s juveniles began dispersing in late September and early October, and so we expect to see this year’s birds making flights away from the Isle of Wight before long. We are always delighted to hear of the excitement birders and members of the public gain from seeing the birds, and we will report the movements of the eagles as much as possible as they disperse. However, please remember that it is not possible to disclose the location of individual birds if they are on private land or other sensitive sites. This is not only to prevent disturbance to the birds themselves, but also to the site and local people. Please keep an eye on the website and our social media, and don’t forget to submit any sightings via our online form. Very many thanks to everyone who has submitted sightings so far, and to everyone who has expressed interest and support for the project – we greatly appreciate it.

A further 12 white-tailed eagles have been released on the Isle of Wight in the next stage of one of England’s landmark conservation projects. Begun in 2019 the project, led by Forestry England and the Roy Dennis Wildlife Foundation, is closely monitoring these iconic birds as they successfully return to the English landscape. 

The project, based on the Isle of Wight, released six birds in 2019 followed by a further seven last year. Evidence from similar reintroductions suggests that the rate of survival to breeding age is around 40%. Ten of the 13 birds previously released have survived and are doing well. 

White-tailed eagles are Britain’s largest birds of prey with a wingspan of up to 2.5 meters and were once widespread across England until human persecution wiped them out. The reintroduction project is bringing them back after an absence of over 240 years by releasing up to 60 birds over five years. It aims to establish an initial population of six to eight pairs with breeding activity not expected to start until 2024 at the earliest. 

Each bird is fitted with a satellite tracker to enable the team to monitor and track their progress. Three years into the project, this data and considerable field observations are showing encouraging signs of the birds developing key skills and improving their understanding of the landscape around them. 

As expected, the previously released birds have explored widely, taking many journeys across Britain as they build up their knowledge of the landscape. One bird released in 2020 crossed the English Channel earlier this year and has since spent time in France, The Netherlands, Germany and Denmark. There have also been several sightings in southern England of white-tailed eagles from Europe, raising hopes that some of these wandering birds will pair up with those released on the Isle of Wight in years to come. Connecting white-tailed eagle populations in this way, is a key long-term aim of the project. 

However far the birds travel, the tracking data clearly shows that the birds consistently return to the Isle of Wight, their release point. This means they see the Island and the surrounding coastline as their home and is an encouraging indicator for potential successful breeding conditions in the future. 

Two birds in particular, G324 and G274 have already formed a close and lasting pairing and are showing some signs of territorial behaviours with other eagles. Whilst it too early to predict, the team are hopeful that these early signs may lead to breeding activity over the next few years.  

Between their explorations, the data and field observations have also shown how the birds have honed their hunting skills as they learn more about their surroundings and the availability of prey. Last winter fish remained a key prey item, with the eagles catching bass off the south-west coast, as well as pirating fish from gulls and cormorants.  Grey mullet is plentiful during the spring and summer in the estuaries around the south coast and has been an important prey item through the past two years. These abundant food supplies around the coasts of the Isle of Wight were one of the key reasons the area was selected for the reintroduction project. 

With each year’s releases there is an opportunity for the youngest birds to observe and learn from those who are more mature. Whilst the older birds will gradually become more territorial, there are still many chances for the younger birds to identify key feeding locations and skills from their older cohort. Over time it is expected that the birds will establish more formal territories and disperse across the south coast of England. 

Birders and members of the public across the country have supported the project by reporting sightings of the eagles and sharing these via @seaeagleengland on social media or via the Roy Dennis Wildlife Foundation website. 

Roy Dennis, MBE, Founder of the Roy Dennis Wildlife Foundation said: “We are now three years into this reintroduction project, and it is extremely encouraging to see just how successfully white-tailed eagles are settling into the English landscape. Highlights for me have included watching the birds learn how to successfully fish all year round and the growing interactions between the birds. I am also always fascinated in tracking some of their huge exploratory flights across England and Europe and their ultimate return back to the Isle of Wight.” 

“We have seen from other reintroduction programmes that returning lost species offers real benefits for the health of our environment, and to people and local economies. None of this would be possible without the support of many people and I would like to thank everyone who has helped us again with this year’s release and ongoing monitoring of the birds.” 

Steve Egerton-Read, White-Tailed Eagle Project Officer, Forestry England, said: “Over the last three years we have closely tracked the progress of these incredible birds. It’s been brilliant to see how well they are fitting into the landscape and we are hopeful that before too long they will breed in England again.” 

“It’s been particularly rewarding to hear from people across the country who are delighted to have seen the birds in their local area. It’s still a real thrill for me to see these incredible birds in the skies above the Isle of Wight and I look forward to the day that they are re-established right across southern England.” 

The reintroduction of white-tailed eagles is being conducted under licence from Natural England, the Government’s wildlife licensing authority. All of the young birds involved in the project are collected under a NatureScot licence from the wild in Scotland and brought to the Isle of Wight.  

Natural England Chair, Tony Juniper, said: “Today’s release marks another important milestone on the road toward the restoration of these magnificent birds as a breeding species in England. I’m so encouraged to see this project go from strength to strength, with this third release enabling white-tailed eagles to strengthen their foothold on the Isle of Wight.” 

“We will continue to work closely with Roy Dennis and his team, Forestry England and various stakeholders to ensure this project serves as a guide for further successful species reintroductions in England, which are a vital part of achieving our overarching goal for nature recovery.”

This year the project again received valuable support from pilot Graham Mountford, and his daughter, Helen, who flew a cohort of birds south from the Outer Hebrides in his plane, thereby greatly reducing the transit time for the birds. 

The Isle of Wight was chosen as the location to reintroduce the white-tailed eagles, also known as sea eagles, as it offers an ideal habitat for these coastal loving birds with plentiful sources of food in the surrounding waters. It also offers a central position on the south coast allowing the birds to disperse and link with other populations in Scotland, Ireland and on the continent.

A comprehensive feasibility study and public surveys were conducted prior to reintroduction and a steering group made up of local organisations and members of the community are helping to guide the project.
