ABSTRACT:
The present invention provides a bird feeder apparatus for providing a readily available supply of feed for birds. The apparatus comprises a telescopic-operational assemblage, a shroud assembly, and a hopper assembly. The telescopic-operational assemblage provides a nonlinear, geometrically-based closure mechanism for effectively closing the bird feeder when a large load is placed upon the shroud assembly such as when a squirrel attempts to gain access to feed outlets of the hopper assembly by positioning itself upon the apparatus. Further, the apparatus provides a partitioned, selectively removable (drop out-type) hopper for enabling easy refills; a feed-level status flag assembly for indicating to the user whether the hopper assembly is full or empty; and at least one surround perch assembly for accommodating birds of various sizes.
