Eagles: Only two species in America, both are large. Bald Eagle, well you know what it looks like. Golden eagle, it's large and has gold tint on its neck if it's full grown, with brown everywhere else. Both of them are fishers but will take small rodents or medium sized ones, depending on the age of the raptor. Kites, too many to list, but they can hunt snails or small fish. They don't do mammals. Hawks and falcons are pretty much the same species divided into accipiters (field hawks) and buetos (forest hawks). There are many species. Harriers, there's only one in america, the northern harrier, a bueto. Buzzards are scavengers and live in Africa, not america. They look like red tailed hawks. They are NOT I REPEAT NOT THE BLACK ONES WITH RED/BLACK FEATHERLESS HEADS. Those are VULTURES. Ospreys are fishers and are black with white specks, or white with black flecks, they live around rivers. There's more information if you google it and get to a really good site with raptor information such as the Peregrine Foundation.
I'm a falconer, I train birds to hunt, so I had to pass an entry exam to get my liscence which involved knowing tons of this stuff.
