Where I come from in NJ we get turkey vultures. HUGE things, and actually a little bit scary. It's fascinating to watch them wheeling above the pines.

Are these live chicks?! In falconry you feed the hawks day-old (dead) chicks. This is not as cruel as it sounds, at least if you are a carnivore, as they are a by-product of the chicken industry. Chicks are sexed shortly after birth, and as it's only the hens which are needed (though I do know someone who, unusually, farms and sells free-range cockerel), the male chicks are gassed. They would just be chucked away, but people who keep birds of prey buy them as food for the birds. A European Eagle Owl can get through 6 - 8 chicks in a day.
