White-tailed eagle

Extinct and reintroduced – What’s the story behind these so-called ‘flying barn doors’?

Bohuš Číčel

Often revered as the “sea eagle,” it is a majestic bird of prey that has made a remarkable comeback from the brink of regional extinction. With conservation efforts leading to successful reintroduction in the 20th century, these raptors have reclaimed their place in the skies of the British Isles, Western Europe, the Faeroes, and certain Mediterranean areas where they had previously vanished.

These large eagles are identified by their broad wingspan, which can reach up to 2.5 meters (8.2 feet), and their notable white tail contrasting with their brown body plumage. As one of the largest eagle species, they command the coastal environments, large lakes, and rivers where they reside, serving as apex predators within their ecosystems.

White-tailed eagles exhibit lifelong monogamy, forming strong pair bonds crucial for cooperative breeding and survival. In the unfortunate event of a partner’s death, however, they display a pragmatic approach to finding new mates, ensuring the continuation of their lineage.

The diet of white-tailed eagles is varied, reflecting their adaptability as opportunistic feeders. Their notoriety for taking farm animals has been historically exaggerated, but they are known to feed on a range of prey, including fish, waterfowl, and carrion. Far from being the ‘pirates’ they were once accused of being, these eagles often clean up dead fish and offal, playing a vital role in their ecological communities.

Their hunting strategy involves keen eyesight to spot potential prey from great distances. Rather than plunging into the water, they prefer to swoop down and snatch their prey with their powerful talons, often putting on a breathtaking display of aerial agility.

The nest, or eyrie, of the White-tailed eagle is an impressive structure, often reused and added to year after year, becoming massive over time. Located in tall trees or on cliff edges, these nests provide a secure place for raising their young
