Jays, crows, doves, and yes squirrels.

Love this feeder. It keeps out the jays, crows, doves and yes, squirrels. It even survived an attack from a 200 plus pound black bear that swiped it off its post and followed it over a deck railing to land 10 feet below into a forsythia bush. Still works like new! Geri – Randolph New Jersey
