Abstract
A birdseed dispenser and birdfeeder incorporating the same are provided. The dispenser has a base assembly mounted to a first opening formed in the sidewall of the birdseed reservoir, including a front plate having a second opening formed therein, a flange extending around the second opening and projecting away from the front plate, and an end wall supported by the flange such that the flange and end wall together define a chamber. The dispenser also includes an apertured piece received in the chamber having a first seed aperture of a first configuration and a second seed aperture of a different configuration. The apertured piece is moveable between a first orientation, which places the first seed aperture in a seed accessible state permitting birds access to the seed, and a second orientation to place the second seed aperture in the seed accessible state.
