Just to add my two cents worth...
Two points (apologies if these have already been made)...
One,if you see one gliding hawk, don't worry about it...its the OTHER one you should be worried about (often glide in pairs or threes)...
Two, if you see a bird early, gentle evasive manoeuvre to avoid...if its close, better to just stand on and hope for the best rather than trying to manoeuvre violently and risk doing damage to the aircraft by the manoeuvre vice the bird.
Totally agree that first and foremost (if you've taken a hit) fly first.
