Abstract: A bird feeder has a vertical feed chamber with a plurality of feed openings defined in it and a perch located below each feed opening. Enclosed conduits, which have inlets that are positioned immediately below the feed openings, empty in an otherwise enclosed overflow chamber. Thus, feed material which is scratched out of the feed openings passes through the conduit into the overflow chamber. The conduit inlet opening is relatively small compared to the size of the bird eating at the feeder, which, coupled with the placement of the perch below the conduit inlet, causes hulls of seeds eaten by the bird and fecal matter dropped by the bird to fall outside of the conduit so that they will not contaminate the seed contained in the overflow chamber. In one embodiment of the feeder there is a plurality of feed chambers which are oriented one on top of another. In this embodiment the conduits associated with the feed openings in each feed chamber empty into the next lower feed chamber.
