Abstract: A housing has a base portion with a recess that holds a supply of bird seed. Walls are foldable upwardly from the base portion to form side walls and a top wall. The front and rear of the walls are open to provide access for birds using the feeder at the front and to allow the rear of the feeder to face a glass surface. The rear of the feeder has a removable attaching strip for connection to a glass surface. Attachment is preferably by a pressure sensitive adhesive. The side walls fold relative to the base and have locking engagement on the recess for confining a pre-packaged bird seed in the recess. The base portion has a flange which serves as a perch for birds at the front of the feeder.
