It looks like this was a bird that got confused and never went south, rather than an incredibly early northward migrant.

What puzzles me about the picture, though, is that I think it was supposed to have been taken in December or January, but it seems like there are deciduous leaves in the background. Or are they pine needles? What's up with that?

I can't imagine any migrant would be flying into the late winter we are having up here? It does sound a little odd. We don't see migrants in southern New England usually til mid April.

I'll believe anything though. 4 or 5 years ago, we had a Rufous Hummingbird at our feeder in late November during a snowstorm. Rufous do not generally live in our region! I have the photo to prove he was here though :-)

I think the photo is just a stock photo of a ruby-throat hummingbird they put on all those maps. I don't think it's a photo of the Plymouth hummer.
