I'd like a second opinion on a bird of prey I saw today with the naked eye outsided my office.
I'm located in the centre of Birmingham.
The bird of prey roughly sparrowhawk sized was attempting to land on the brick facade of the vertical side wall of an office block 20 floors up.
It failed to get a grip and flew off.
It was being quite noisy, which drew my attention.
It's back was grey/light brown in colour and it had a pale underparts with a dark thick barring across the tail feathers. The tail was not particularily short and seeme proportioned to the wings.
The apparent agitated alarm call it made while failing to land had the following pattern (for want of a better word) with spaces being gaps of a fraction of a second (replace the D with a sharp hawk note):
D D D D D DDDDD D D
prior to that it had made a single D D call.
