Three Sea Eagles disappear in suspicious circumstances

We are deeply concerned that three White-Tailed Eagles have disappeared in suspicious circumstances. The cases include a chick born in the wild earlier this year in Sussex, one of the first White-Tailed Eagles to fledge in England for hundreds of years.

Roy Dennis publishes a new book

Roy Dennis’ latest book – The Highland Cow and the Horse of the Woods – looks at how to prevent the second extinction of the capercaillie, the distinctive woodland grouse of Scotland.

Two pairs of White Tailed Sea Eagle breed in England in 2025

We are delighted to report that two pairs of White-Tailed Eagles have bred successfully in southern England this summer, rearing a total of three chicks. G405 and G471 bred for a third successive year in Sussex, rearing two chicks, while a second pair, G463 and G466, bred in Dorset for the first time, with a single chick fledging.

Established 1995

The Foundation was set-up by Roy Dennis in June 1995 and since then we have undertaken innovative species restoration work, been at forefront of bird migration research, and become a leading advocate for the restoration of natural ecosystems. We are a non-membership charitable trust dedicated to wildlife, with a special emphasis on species recovery projects and the restoration of natural ecosystems.

Nature restoration through species recovery

The foundation works on the frontline of nature recovery to return species threatened by extinction or lost entirely to the UK.
