ABSTRACT:
This invention is directed to a feeder construction and one which is especially adapted as a bird feeder wherein a novel and cooperative container and closure configuration is presented in such a manner that a highly efficient and practical feeder is produced. In the most preferred form, the container takes the shape of a hollow toroid having an interfitting closure in the form of an encircling ring slidable within a recessed channel in the outer surface of the container. Spaced openings in the closure are capable of orientation with a fill opening within the container upon rotational movement there between so as to provide fill access to the container. The lower interior portion of the toroidal shaped container is provided with a feed access opening for birds and the like. Furthermore, by varying the size of the central laterally extending recess within the container, various species of birds may be restricted from access to the feed opening.
