Avian Predators

Avian Predators as opposed to "Birds of Prey," (raptors) The latter is specifically defined in ornithology to include only certain species: Hawks, eagles, owls, vultures etc. Not surprisingly, I relate most to mammals and so my definition of "Avian Predators" is any bird that includes mammals in it's regular diet. For non-raptors, mammals may represent a relatively small portion of their diet, but a Kingfisher eating a mouse hasn't mistaken it for a fish. No re-pinning limits on this board.
