Deishar’s first flight south

Deishar set off on migration three day’s later than her brother Carr, but, like her sibling, she has made excellent progress south since leaving Scotland.

Deishar began her migration on 4th September and very quickly made up for lost time. Aided by a tailwind she flew just under 500 km to Cheshire on her first day of migration, flying south through central Scotland, and then across the Solway Firth and Morcambe Bay – which she crossed after dark.

Next morning Deishar was flying again before 06:00, heading powerfully south through Shropshire and then Herefordshire. At 10:16 she was 186 metres above the Severn Estuary and, at 10:50, 550 metres above the centre of Bristol. At 12:32 she headed out across the English Channel from the Dorset coast, west of Abbotsbury. She flew 135 km to Guernsey and then a further 98 km across the sea to the Brittany coast at Saint Brieuc. She was making such fast progress that she had now overtaken her brother, Carr, who arrived and then roosted on Guernsey a few hours after Deishar had passed through. She continued flying for a further 90 minutes after reaching French airspace, before roosting in an area of woodland near Plumeliau.

Deishar arrived in Brittany just two days after leaving the Highlands

Next morning Deishar continued south-west towards the Atlantic coast. Unlike her brother who then flew direct across the Bay of Biscay to Spain, Deishar always kept the coast in sight as she headed south. By 16:48 that afternoon she had flown 275 km and was over Ile d’Oleron just to the south-west of La Rochelle. She continued south over the River Gironde and then settled to roost in a forested area near the village of Naujac-sur-Mer, around 50 km north-west of Bordeaux.

Next morning Deishar headed south-east away from the coast and towards the Pyrenees. She flew just under 200km before roosting beside the River Adour. Although she arrived too late to fish that evening, the data indicates she may have caught her first fish since leaving Scotland, soon after first light the next morning.

Deishar roosted beside the River on the evening of 7th September, and the data suggests she fished in the river the next morning.

Deishar resumed her journey at around 11:00 on 8t September and reached the Pyrenees two-and-a-half hours later. Her satellite transmitter – which logs her location once every three minutes – showed how she flew picked her way through the imposing mountains to avoid crossing the highest peaks. Nevertheless she still reached a maximum altitude of over 2564 metres above sea level as she flew through the mountains.

Once clear of the mountains, Deishar continued south until 19:44 local time when she settled to roost beside the River Ebro, 10 km east of  Zaragoza. She had flown 250 km during the course of the day.

Having reached northern Spain, Deishar showed no signs of letting up and she made the most of excellent flying conditions on 9th September, soaring and gliding through Aragon, sometimes reaching altitudes in excess of over 3000 metres. She continued flying until 20:00 by which point she had covered a further 300 km and was now 45 km south-west of Valencia.

Deishar made the most of excellent thermal conditions as she soared south through Spain, climbing on thermal updrafts and then gliding forwards.

Next morning Deishar continued on the same southerly heading and at 14:00 local time she reached the south-east coast of Mercia, south-west of La Manga and headed across the sea. The crossing to Africa is much further here than the Strait of Gibraltar where many Ospreys cross, but Desihar made light work of it, flying 210 km across the sea in four-and-a-quarter hours.

Deishar made a 200km sea crossing from Spain to Algeria.

Having reached Algeria, Deishar continued flying for a further 60 km before roosting on the edge of the town of Relizane. Deishar is now much further east than her brother, Carr, and will have a longer crossing of the Sahara unless she makes a drastic turn to the south-west. Her transmitter works through the mobile network and so we may not receive any further updates from her until she is across the Sahara. Let’s hope she makes it – but it is a difficult journey for you Ospreys on their first autumn migration.

Deishar has reached Algeria just seven days after leaving her nest in the Scottish Highlands.
