I just want to confirm this because we've never, ever seen this behaviour before, nor see just three at once. Usually, we do not see them in the snowy months and when they arrive in the spring, there are dozens, if not hundreds.
Certianly look like it to me, and they look cold, too ;-)
Sometimes happens that odd birds of migratory species fail to migrate; often, their prospects are not good but they can survive if they find a good food source. Sibley's map shows you're on the northern edge of where they normally winter, so I'd guess these will be alright unless the winter is very severe.
Thank you for your replies. They sure were cold, with the temp at 21F. There was a windchill, but I did not want to know what it was.
These birds did look so pathetic that I couldn't help but feel sympathy for them.
