White-Tailed Eagles on the Isle of Mull

Keeping Tabs on Mull's Sea Eagles

New Age Eagles of the 21st Century

Plastic wing tags, colour coded to represent the year of tagging and individually marked with a letter or symbol were previously fitted to the wings of young eaglets on Mull. As the local population of White-tailed Eagles increased it became more difficult to tag all the accessible young eaglets and less important to individually identify each bird. Critics thought that the fitting of large, coloured wing tags rather invasive and new ways of marking young were investigated. Young birds are now fitted with a coloured leg ring that denotes the year that the eagle fledged and an inscription that identifies the individual bird.

The wing tagging programme ceased at the end of the 2007 'eagle season' and, since then, four chicks, from separate nests on the Isle of Mull have been fitted with radio satellite tags, in order that greater and more up-to-date information can be processed regarding the whereabouts of these birds.

The immature bird (White, 'F'), pictured above, was photographed at Loch Scridain, Mull in early January 2010. It is a young male that fledged from a nest on the island of Jura, south of Mull, in 2007.
