They are considered an endangered bird due to rapid population declines in their Asian breeding grounds.
Sakers often hunt horizontally like Kestrels, not vertically like Peregrines.
I watched a Saker swoop down on an unsuspecting pigeon, but my presence, in response to the pigeon cries, called off the hunt!
Cheers to you from the remarkable and endangered Saker Falcons~
