ABSTRACT:
A dual purpose bird feeder for use mounted upon a post with a squirrel baffle preventing climbing upon the feeder or for use in a free hanging relation where it is supported on a chain. The bird feeder is comprised of a frusto-conical hollow feeder housing with a tray at the bottom and flat shallow roof at the top. In the freely supported relation the feeder tray has a radius not exceeding about 55% of the radius of the roof and the outer periphery is positioned underneath the upper portion of the housing. The depth of the tray beneath the roof also does not exceed about one-half of the radius of the roof. This relationship prevents or discourages squirrels or large undesirable birds from using the feeder tray. In the post supported version the squirrel barrier baffle is of the same frusto-conical construction as the feeder housing for ease in manufacture and is positioned underneath the tray. A cylindrical baffle may depend from the tray to which the frusto-conical baffle may be removably attached. Means are provided for a central post to connect to the feeder. The inverted upwardly flaring baffle and its spacing of the bottom wall from the central support post effectively prevents squirrels from climbing the post on the feeder tray.
