I hear someone shout “Kestrel!”
There’s a shout of “Kestrel!” and I train my lens on the sky. A Common Kestrel is being mobbed by a Carrion Crow.
It only takes one Crow to form a mob.

As they fly away I take a few photographs in the hope that something might be usable or that something interesting might happen.
It does.
They have a talons-out midair fight and come close to grappling with each other.

That was spectacular. All I have to do now is delete the hundred boring photographs I took before something interesting happened.
