A large black crow-sized bird swooped upwatds past myin Sharon Massachusetts. The bird had a well defined white stripe on his throat. He looked like he swerved up just before he hit the glass. I only saw the underside of the bird, but I was very close to it, and definitely saw a well defined white stripe on his throat. The problem is, I don't think the crows (or even the ravens) in New England have white stripes - ever! I've never seen one, and I grew up in a birding hosehold. I don't live near the ocean, either. It's probably twenty miles to the nearest salt water.
I've looked everywhere for a reference to a bird like this that would be seen in Massachusetts. The only hint was on this site in the description of a Fish Crow, where it says "Throat: White" under the "Identification" tab But it also says the underside is solid black, so it may be a misprint.
I posted a rough picture of what I saw out myin the gallery. Any ideas would be appreciated. I've been up all night looking for this bird!
