A human malimprint is a bird that is exposed to people too much when it is a chick. Instead of recognizing other birds as its own species, it confuses humans with its own species. As a result, it probably won't be afraid of humans, and won't relate very well to its own species.
At the raptor center, we take it birds of prey that are injured or orphaned, and fix and release them if possible. We also do presentations for educational purposes, so we keep representatives of many of the species, those that are healthy, but non-releasable.
This one, Jake, is quite a character. He acts more intelligent than most of the birds, and is very alert and curious. When entering his cage, you've got to show him your hands, so he sees that you don't have food- sometimes you even have to poke him away with your foot. He's been trained to fly on a line to the glove, and I've had the privledge to do that several times, and it's a neat experience.
