All About Yellow Rumped Warblers

We've yellow rumped warblers two times at the bird banding barn. The males are bright yellow, and the females are brownish gray. They eat mostly berries. Stay here in the winter, so they don't migrate. They don't eat many insects, so they can stay here. It's too cold for insects, they would have to migrate south. The nickname that the research assistants call them is "Butter Butts."

Facts we learned while making this post:

The female builds the nest out of twigs and grass. She might also use moose, horse and deer hairs! It is a cup shape at the end.
