My Dad just called me. He's sitting in the kitchen, watching a coupld hundred birds attack his bird feeders. They have a big storm headed their way (Vermont) and the birds are feeding like crazy.
Anyway, he said he was sitting there, when all of a sudden, this hawk comes flying in a picks off a finch of some kind. He proceeded to sit there and start tearing into it. My Dad said the wings and feathers were getting pulled off, all over the snow... 
He looked it up and said it's a Sharp shinned hawk. I guess they have a reputation for hanging around bird feeders and plucking off the unsuspecting little guys.
Just thought it was funny.
