White-tailed Eagles Return to England: New Sightings and Their Impact on the Ecosystem

Recently, two massive silhouettes of white-tailed eagles were spotted over the Ardingly Reservoir in West Sussex. These birds, which have a wingspan of up to two and a half meters, were observed by local birdwatcher Henry Sharkey just minutes before dusk. This sighting occurred just two days after another sea eagle was photographed in Ashdown Forest, highlighting the increasing activity of these birds in the region.

A significant number of white-tailed eagle sightings within a 50-kilometer radius indicate that these birds are not merely passing through but have begun to actively explore new territories. This suggests that they may be settling in the area for the long term, demonstrating signs of permanent habitation rather than incidental migration.

It is important to note that the return of white-tailed eagles has been made possible through a reintroduction program launched in 2019. As part of this initiative, 45 individuals were released along the southern coast of Great Britain. The results of this effort have been swift: by 2025, wild chicks began hatching both in Sussex and Dorset. This marked a significant moment, as the largest bird of prey in the UK began nesting in England once again after a 240-year absence. The last known pair of white-tailed eagles in these parts raised young back in 1780 on the cliffs of Culver, located on the Isle of Wight, after which the species was completely eradicated due to human persecution.

The current project, implemented under the auspices of Forestry England and the Roy Dennis Wildlife Foundation, operates according to a precise algorithm. Young birds are taken from licensed nests in Scotland, kept in aviaries on the Isle of Wight, and fitted with GPS trackers before their release. This allows scientists to monitor every maneuver of the predator in real-time. The success of the program has been quicker than anticipated: while the initial goal was to create six to eight pairs over a decade, by 2023, the first chick was born in Sussex, with five more expected in the following two years.

The white-tailed eagle, often referred to as the 'flying door' due to the distinctive shape of its wings, typically preys on fish, waterfowl, and does not shy away from carrion. These birds build gigantic nests, called aeries, atop old trees, adding sticks to them each year until the structure reaches two meters in diameter. However, the return of such an apex predator has caused significant tension among farmers. After years of denial, official bodies, including NatureScot, have acknowledged that eagles can attack healthy livestock.

The agency's action plan states: 'More recent works confirm that in some cases, white-tailed eagles bring the carcasses of recently deceased lambs to the nest, and in a number of cases, these lambs were likely healthy when caught.' This has served as conclusive evidence in long-standing debates about whether the birds only prey on the weak. On one farm in Scotland, losses attributed to eagles were estimated at 181 lambs over six years.

Despite the financial risks for farmers, the ecosystem in the region is receiving a powerful boost towards restoring balance. Birdwatching tourism has already begun to generate profits for communities, as has previously occurred on the islands of Mull and Skye. Meanwhile, the 1981 Wildlife and Countryside Act strictly protects these giants, yet troubling reports of three eagles disappearing under suspicious circumstances indicate that illegal hunting remains a significant threat to a species that has only just begun to reclaim its place in the English skies.
