If you are a small animal in a field, and see this, it’s already too late. These birds hunt in packs, like wolves.
They are originally from the Southwestern US, down through South America. However they have spread worldwide. A very intelligent bird now being used in falconry. Being a smart bird, they escape and do well wherever they are.
This particular bird has an incredibly love of flying, and people. The photograph above was taken as he flew right to me, turning just enough to slip by me while gently brushing me with his wing tips. Which he enjoyed enough to do a U Turn in the air and try again.
