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.

Abstract: A squirrel proof bird feeder having bird feeder holes of a construction to minimize loss of seed by scattering or wind blowing. The bird feeder has a removable conical top of an inverted hip roof construction with the major portion of the upper region of the top having a steep pitch with the lower eaves or border having a gentle pitch which construction tends to dump a squirrel climbing upon the roof from a suspended chain. The bird feeder housing has feeder holes which communicate with the interior through horizontal feeder tubes which are open on the bottom and closed by a baffle at the inner end which while permitting a flow of seed under the end portion of the feeder tube and under the bottom sides restricts the flow when the bird feeder is blown by the wind or otherwise disturbed by feeding birds or squirrels climbing on the top of the feeder.
