“These eight birds have all disappeared in an area where driven grouse moor management dominates the landscape, and where there have been many previous cases of illegal killing of protected raptors, including the poisoning of a golden eagle and a white-tailed eagle as recently as 2010.
Given the reliability of the transmitters, the chance of so many birds disappearing over such a short timescale without some kind of human interference is so small as to be negligible. The pattern we see here is consistent with the birds having been killed and the transmitters destroyed.” (http://www.rspb.org.uk/media/releases/423406-satellite-tagged-golden-eagles-disappearing-in-the-monadhliath-mountains)
“I have instructed officials to analyse the evidence from around 90 surviving and missing satellite-tagged eagles, to discover if there is a pattern of suspicious activity. … The public rightly expects all businesses in Scotland to obey the law. Let me be clear: grouse shooting is no exception.” (http://news.scotland.gov.uk/News/Eagle-disappearance-review-2881.aspx)
Let’s not leap to any conclusions: this could be the work of extreme conservationists, systematically bumping off birds of prey in the vicinity of grouse moors over decades in a bid to undermine the inglorious twelfth. Or alien abductions. Or spontaneous combustion.
“The probability of 5 or more male Hen Harriers disappearing through ‘normal’ levels of mortality over a breeding period from 9 nests is 0.0033% … So there must be something pretty odd happening.” (http://markavery.info/2015/09/22/wondering2/)
Yes, that’s a 1 in over 30,000 chance. Pretty unlikely. Well done the grouse shooting industry for allowing us to experience such a rare event.
