text: The RSPB: News: Satellite tagged golden eagles disappearing in the Monadhliath mountains
  Despite comprehensive searches, after consultation with the Police, of the areas around the last recorded positions of all eight eagles none of the birds or transmitters have been recovered, and no further data has been received from the transmitters. The first eagle vanished after last being recorded in the hills above Strathdearn in November 2011; following this a second disappeared in July 2012, and a third in March 2014. In October 2014, transmissions from two further eagles stopped at another location across the valley, three weeks apart. Three eagles' tags stopped transmitting at a scatter of locations in the hills above the River Findhorn, in May, June and the latest bird, Brodie, in early July this year [1].

  2. Satellite-tagged golden eagles found to have been illegally killed:

  - 1 poisoned in Glenbuchat, Strathdon, in 2011
  - 1 poisoned in Lochaber in 2012
  - 1 illegally trapped in Angus in 2012
  - 1 poisoned in Angus in 2013
  3. Other raptors that have gone off radar include three satellite-tagged golden eagles and a white-tailed eagle which disappeared in September 2011, February 2012, May 2013 and April 2014 respectively, all in upper Donside. Other tagged golden eagles have disappeared in west Aberdeenshire (May 2012) and Angus (February 2011).
  4. A golden eagle and white-tailed eagle found dead in the Monadhliath mountains in 2010 were confirmed as having been illegally poisoned with carbofuran at the laboratory of Science and Advice for Scottish Agriculture (SASA) – SASA ref. No. 10123
  5. A Scottish Natural Heritage review of wildlife crime records and other threats found that the golden eagle population in the the Monadhliath mountains had unfavourable conservation status, with poisoning in particular being associated with grouse moors.
