Abstract: A universal window bird feeder having a dish portion and a hood portion spaced thereabove with an elongated rod of non-circular section extending therebetween. Apertures on the hood and dish portions cooperate with said rod to non-rotatably mount said portions thereon. Bracket means are provided for either suspending or for supporting the feeder from beneath the dish portion. Alternative suction cup means are provided for mounting the feeder on a window surface.

Abstract: A perch for bird feeders and the like of the type comprising a vertically disposed housing having feed therein and an aperture extending therethrough for permitting access by the birds, said perch comprising a pair of substantially vertical side walls which extend outwardly from the housing adjacent opposite sides of the aperture with a rod extending between the walls on which a bird may light. In use, feed material within the feeder is easily accessible through the aperture to smaller birds located on the perch but not to larger birds since they cannot insert their relatively large heads between the side walls and their overall large size prevents them from curling their heads downwardly and forwardly to insert their beaks into the aperture.

Abstract: A bird feeder construction adjustable for feeding birds exhibiting all kinds of feeding behavior patterns including, for example, birds which feed while perched and birds which feed while in a clinging position. In general the construction includes a feed assembly having a container portion and a platform portion, the container including an open top defining an upper feed access for nonclinging or perch type feeding birds and the platform provided with a plurality of openings forming lower feed access openings for small cling feeding type birds. In addition, a hood member is provided so as to protect the feed assembly from the elements and unwanted species including large birds, squirrels, and the like. Also, means are provided for enabling the feed assembly to be independently pivotally movable with respect to the hood member.
