I wonder if that explains this weird little thing my male Senegal, Pete, about 6 yrs old, does when he's on me...he does this strange little "gagging" thing, kind of like I see the wild birds do when they're feeding their babies. I have a friend, also weird, who will chew up a pretzel and let Pete eat it out of her mouth. Boy, does he love that...flutters his wings and gets all excited. There aren't very many people he likes that well, and my family knows who can and cannot stick their hand in his cage....
