  • Publication number: 20040123808
    Abstract: A bird feeder comprising an elongate bird feed container open a top end and having a base closing a bottom end thereof. A hanging member for hanging the bird feeder and a removable cover with both an open position, in which the cover is spaced from the top end to facilitate supplying bird feed, and a closed position in which the cover covers the top end. A cage structure for encasing the bird feed container. The bird feed container is a material with a plurality of access openings formed therein which are sized to retain bird feed but also facilitate dispensing and feeding of the bird feed therethrough when accessed by a desired bird. An outer surface of the material of the bird feed container is spaced sufficiently away from an inwardly facing surface of a sidewall of the cage structure to allow only selected or small birds to access and retrieve bird feed while preventing undesired larger non-clingy birds and animals from accessing bird feed contained within the bird feed container.
