I am sorry, but I don't have any advice either.....but Mojo goes crazy over birds and flies! If he sees a bird outside, he will bark and grrrrrrrowl at it because they are in HIS yard!

LilyGrace is the same w/ crows and squirrels....when we first got her, she would run from tree to tree after them...we have been working w/ her off leash....these little babies.....
