I wasn't able to ID this bird. It was sitting on a branch of a tree when I saw it, but it was against the light and looked dark enough that I couldn't tell. Then it flew! I grabbed a shot and hoped I got it. The P900 I shot with isn't an action camera, like a DSLR is. The bird almost got away! It was on the left side of a horizontal frame, and is much better as a vertical. Would appreciate any feedback on the ID.

Could it be a Black Phoebe? I did get another photo of the bird before it flew away - http://www.pbase.com/image/164008387

It has been confirmed as a Black Phoebe!
