I believe this is a 1st year Juvenile Merlin or Prairie Falcon that has been using the VCB as its hunting grounds. This afternoon it killed this Pigeon by running it into the glass above the loading dock doors. You can still see the imprint on the glass. Last week it caught another Pigeon on the other side of the building. I think it has come up with a very successful hunting technique. It also does not seem too stressed by people. This photo was made within 3 yards of the dinner menu.
