Two eaglets in a nest on the RSPB Forsinard Flows Reserve in North Sutherland were ringed and tagged on 30th June 2010.  The two transmitters fitted to these young were provided by Scottish Natural Heritage, through Professor Des Thompson.  Norrie Russell, the Site Manager of the RSPB Forsinard Flows Reserve, and Colin Mair, took us to the nest, and I was helped by David Clark and Ryan Munro.  When David started climbing to the nest, the smaller male eaglet took off and flew about 500 yards and landed in the heather.  We recaptured it and after ringing and tagging it was placed back into the nest with its sister.   The chick was in good condition with no stress bars but was 1.2kg lighter than its female sibling.  This young eagle has not yet been named, but is recognised for the time being as 107.

 Annual Movements

In 2010, 107 ranged very far across Scotland, including Assynt, Easter Ross, Wester Ross, Aberdeenshire, Perthshire and Argyll. On the 25th November 2010, he was 170 miles away from his natal area, in Dunoon. This is the further recorded dispersal for a Scottish golden eagle.  107 spent early 2011 in Perthshire, Aberdeenshire and the Angus Glens and he then moved to the Monadhliaths.  During this time he overlapped with his sister three times. In March/April, he moved back to Caithness and Sutherland, closer to his natal area.  In May he returned to the Monadhliaths once more and then spent most of the summer in north Sutherland and Caithness.  He continued to range widely but spent a lot of time in and around Sutherland.
