Henry went to visit the Farr Estate just up the valley from Coignafearn. It’s often called the Glen Kyllachy & Farr Estate.
He doesn’t look very happy.
Raptor populations in this area and nearby have suffered a long history of persecution, as recognised by Scotland’s Moorland Forum (see here). It’s a real mystery who is responsible for this because there has only ever been one prosecution. A conviction was secured but was later quashed on appeal.
Here are some records on what has reportedly been found over the years (data from RSPB reports):
1987: Poisoned bait, Kyllachy.
1991: Poisoned eagle, Farr.
1991: Hen harrier nest destroyed, Farr Estate.
August 2008: Poisoned red kite (Carbofuran), Glen Kyllachy & Farr Estate
April 2009: Poisoned red kite (Carbofuran), Glen Kyllachy & Farr Estate
May 2010: Poisoned red kite (Aldicarb), Glen Kyllachy & Farr Estate
June 2010: Poisoned white-tailed eagle (Carbofuran), Glen Kyllachy & Farr Estate
June 2010: Poisoned golden eagle (Carbofuran), Glen Kyllachy & Farr Estate
May 2011: Poisoned red kite (Carbofuran & Bendiocarb), Glen Kyllachy & Farr Estate
June 2011: Attempted shooting of a kestrel (Farr).
The six poisoned raptors found in the three year period between 2008-2011 (4 red kites, 1 golden eagle, 1 white-tailed eagle) prompted a police raid in July 2011. You can read about the outcome here (page 26).

Looks and sounds like a war zone. How utterly depressing. Get out while you can Henry!
You guys are not as good as I thought you were…….
June 2011; Attempted shooting of a red kite from both an estate road & then public road
I’ve seen better looking landfill sites!
Well – I’ve seen a better looking pit bing.
