Glad to see this thread is still flying along.
I've had a winter visitor this year that I've had a hard time identifying, which is unusual because I've been at this for some years. Anyway, it's a tiny bright olive green bird, smaller than a Sparrow, slightly larger than a Chickadee. It loves peanut butter and is solitary. I live in the DFW area. Not being able to figure this out has been keeping me awake at night.
Anybody have a clue? Possibly a Warbler or Vireo?
We had several small bright green birds here in Central Texas last year.
They arrived at the same time as the painted bunting, so it could be either a female painted bunting, or another type of bunting.
