It’s been more than 170 years since eagles soared above Eryri, its mountains once synonymous with the majestic bird of prey. A video clip posted online has raised hopes that golden eagles may have now returned to their cultural home.

A photographer brewing a cup of tea by the Afon Glaslyn spotted a large bird flying high above Gelert’s Grave in the village of Beddgelert. His footage, taken at some distance, has divided opinion but some experts believe it shows a golden eagle. The spectacular bird has a wingspan of up to 2.3 metres.

Osprey and red kite were ruled out, with a buzzard the most likely alternative. Widespread across North Wales, they are commonly mistaken for eagles.
