Hi, I would recommend this book:
Sharing the Skies - Transport Canada (TP 13549 - Sharing the Skies - Transport Canada
from the book:
If you encounter birds, the most effective evasive action may be to climb above them while maintaining a safe speed. Biologists have observed that some birds break downwards when threatened. Other recent studies indicate that some birds may view aircraft as immobile objects, and turn slowly away when at a perceived safe distance.
Bird size can be estimated by observing the wing-beat rate; the slower the beat, the larger the bird—and the greater the potential for damage.
Also, more eyeballs = more chance of spottings the birds, so if you can, try to look out the window together..
