Do crows migrate?

My sister Diane, in Halifax, Nova Scotia, posted a photo of  crows on Facebook and wondered if crows migrate in cold weather.   I think many people wonder the same thing.   Yes, in fact, crows do migrate ... partially ... and in the north, especially.   In the summer, crows will migrate north as far as the North West Territories to James Bay to Labrador.   Those northern crows head south for the winter.   But that may be only as far south as the Canada/US. border or the Great Lakes.   The photo below was taken in the fall, near to where I live north of Lake Ontario.  Crows, when not nesting and raising young birds, are very communal and do flock with other crows ... sometimes even in the tens of thousands.  This is especially true on winter nights.   They are omnivores and will eat anything they can get their beaks on; mostly waste grain in the winter.
