“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.
