Never seen one of these before but it turns out it lives in every U.S. state.
An interesting thing about the birdfeeder is how birds species time share on it. Blue Jays, when they descend on it, will take over all the surrounding trees. Several dozens of them raiding the feeder for 20 minutes. None of them were there before, none left after. They act as a group, are punctual, and expedient.
