I live in Newfoundland, Canada. Two days ago I saw what looks like a yellow warbler in our yard (according to google images). We get them in the summer, but never after September. It's been a very warm fall/winter. He's hanging out with our American Goldfinches, and comes to the feeder when they do. He seems to be eating sunflower seeds that have already been broken open, but is having a hard time of it. He goes all over the trees looking for bugs too. According to what I have read up on them, warblers only eat insects. Does anyone know if they can survive on seed? Any ideas on what I can do to try and make it a little easier for this guy? He's going to have a very hard time of it, otherwise.
