Patent abstract
A bird feed dispenser for wild birds with squirrel-resistant mechanism that occludes feed ports when a non-bird having a weight sufficient to activate the mechanism engages a portion of the roof or a perch thereon. The dispenser includes at least two feed ports, corresponding perches, and a torsion spring that provide biasing force for the mechanism. The occlusion of feed ports in the dispenser is such that when a non-bird having weight sufficient to activate the mechanism engages a portion of the roof or a perch thereon, all the feed ports are obstructed.
