The white-tailed eagle — with a wingspan of up to 2.4 metres, the largest eagle in Britain — was extinct in Wales for nearly two centuries before a reintroduction programme brought it back to the Dyfi valley. The Montgomeryshire Wildlife Trust's Cors Dyfi Reserve is the best viewing point, with live camera feeds in season and regular sightings of the resident birds over the estuary. This is Experience #62 of the Snowdonia 100.

The Reintroduction
White-tailed eagles were extinct in England and Wales by the early 20th century. The reintroduction programme, which began in Wales in 2021, released birds from wild populations in continental Europe. The Dyfi estuary — with its combination of fish, wildfowl, and undisturbed wetland habitat — attracted the first breeding pair. A nest was confirmed in 2023. The birds are large enough to be visible from considerable distances — if you see something that appears impossibly large, soaring over the estuary, it is probably an eagle.
Size Context
The white-tailed eagle's wingspan of up to 2.4 metres means it is roughly twice the size of a buzzard. Birders who see their first one frequently describe a moment of disbelief — the scale simply doesn't match expectations. The vernacular name "flying barn door" captures something of the impression. Watching one from the Cors Dyfi hide, dropping towards the estuary to take a fish, is an experience that recalibrates your sense of what wild Britain can contain.
