Yellow-Rumped Warbler

Did you hear about the tree that had to take time off of work in autumn?

It was on paid leaf.

Interesting Fact: In winter, Yellow-rumped Warblers join flocks and switch to eating berries from fruiting shrubs. Sometimes the flocks are enormous groups consisting entirely of Yellow-rumped Warblers. If another bird gets too close, Yellow-rumped Warblers indicate the infraction by holding the body horizontally, fanning the tail, and raising it to form a right angle with its body.
