US Patent 8931434 Collapsible bird feeder

A bird feeder includes a seed reservoir formed as two or more telescopic components, which are reducible in size when not in use and which may be telescopically expanded by the owner thereof when in use to define a full-length seed reservoir. The bottom end of the reservoir is received in a base having a conically-shaped seed spreader situated therein, and the upper section of the reservoir is mounted to the underside of a hemispherically-shaped, anti-squirrel dome.
