Hen Harrier
Here's another photo of the female Hen Harrier who's nest we visited under licence to ring the chicks. This photo shows her beak open as she was "chittering", an alarm call you are unlikely to hear away from the nest. Here is the chittering call recorded in France on the excellent Xeno-canto website: xeno-canto.org/670733 Because of the extreme vulnerability to persecution I have been asked to withhold even the general area where this was taken, but it was in the north of England.
