The Hawk Has Landed - in the BackYard

So I was busy snapping the usual photos of squirrels and birds in the backyard when an hour later, after all the animals and birds had left, an extra big bird stopped by, one I've never seen before. Needless to say, I was all excited... until I read later they mainly feed on smaller birds.😱
(I did not want to scare it away so the photos were taken through a glass door...)
