Abstract
The bird feeder of the present invention includes a feed tray, a housing having bird feed which is disposed above the feed tray, a door which controls the amount of feed delivered from the housing to the feed tray, a cover disposed above the housing and means mounting these components on a pole. The housing has downwardly sloping channels formed therein which extend radially outwardly, and feed apertures formed at its lower end which are circumferentially spaced and aligned with the channels. The door is rotatably secured to the housing and includes openings which register with the feed apertures of the housing for allowing bird feed to pass through the feed apertures and onto the feed tray. The door is rotatably movable between an open position and a closed position.
