Put out birdseed, and the birds and squirrels fight for the last nibble. But who will let you know when the seed is gone? The squirrel chatters, “Excuse me…your birdfeeder is empty,” while the bird chirps (on XE8522, sold separately), “Excuse me…the squirrel ate all our birdseed.” 16"w x 12½"h. Predrilled 1/8" holes at each corner for mounting. Tin. Made in USA.
