A squirrel-proof bird feeder and feed level control device is described. The bird feeder includes a vertically disposed inner housing member which is positioned within a vertically disposed outer housing member with each of the housing members including a plurality of vertically spaced-apart housing segments. The spacing of the housing segments divide feed openings therebetween. A combination feed level control and feed port device is positioned between each of the housing segments of the inner housing member so that feed ports are provided therebetween. The outer housing member has a plurality of feed openings formed therein which register with the feed ports of the combination devices when the outer housing member is in its first position. If a squirrel should move onto the outer housing member, the outer housing member moves downwardly with respect to the inner housing member so that the feed openings in the outer housing member do not register with the feed ports of the combination devices. A spring interconnects the inner and outer housing members to yieldably maintain the outer housing member in its first position. The combination feed level control and feed ports not only function as a feed level control mechanism but also provide feed ports at the lower end thereof.
