The eagle's movement's prior to its discovery poisoned.
Tests carried out by the Scottish Government laboratory of Science and Advice for Scottish agriculture confirmed that the bird had been poisoned. The eagle, named "Fearnan", was ringed as a chick in a nest near Loch Tay in Perthshire in June 2011 and had spent much of its life in Badenoch, before moving to the Angus glens in early November. Just three weeks later, it had been poisoned.

Stuart Housden, Director of RSPB Scotland, said: "This appalling incident involving a species recently voted as the nation's favourite bird, marks a dreadful end to the Year of Natural Scotland. We have recently submitted a petition to the Scottish Government, asking for the Golden Eaggle to be officially designated as the national bird of Scotland. Incidents such as this show very clearly why this iconic bird needs not just our recognition, but also greater protection. We sincerely hope that those responsible are swiftly brought to justice and would encourage those with information to come forward."
In the past five and a half years, another four eagles, a Red Kite and seven Buzzards have been shot, poisoned or trapped on sporting estates situated in the Angus Glens. In January 2013, the nest tree of a pair of White-tailed Eagles was felled. No-one has been prosecuted for any of these offences.

Mr Housden added: "I will be asking the environment spokesperson of all the parties in the Scottish Parliament to take cross-party action to stiffen the penalties for those convicted of such offences and to look again at the regulation of sport shooting. The current state of affairs is simply unacceptable."
A recent report by RSPB Scotland revealed that a significant number of incidents of illegal killing of birds of prey took place in areas managed for driven grouse shooting.
