It came in response to my question about the bird craving raw meat (only beef, fish, chicken). I was worried about giving her hamburger with the possibility of salmonella or whatever in it.
He said the bird could eat, digest and enjoy contaminated food that would kill a human. They supposedly have reptilian digestive systems. Same thing that works for vultures.
This is not my bird, but it looks very much like her. She is heavy, for a bird... almost 2 pounds, and has recently decided to become my six-year-old granddaughter's personal body guard. We have a dog (boxer) and two cats and all three of those pets show great respect for the bird. I don't know what kind of encounters it took to gain that respect, but I guess having a beak that can crush a broomstick put her in a good bargaining position.
