ABSTRACT:
A hanging or fixedly suspended bird feeder embodies an upright, tubular, smooth-walled, feed container configured with feed ports in which at least lower portions of the lips of the ports are recessed radially inward from the side wall of the container into the base edge for the purpose of deterring marauding squirrels from obtaining a claw hold on the container wall. A saucer-shaped perch extends radially from beneath the feed container, suspended by elastic cord which yields and stretches under weight of a squirrel, thwarting attempts by squirrels to feed by upsetting the perch thereby ejecting the creatures to the ground.
