Abstract
In combination with a bird feeder including a vertically disposed hollow housing having a peripheral side wall, a removable top cover and a bottom wall and at least one aperture in the side wall, a combination baffle, seed tray and perch device adapted for mounting on the outside of the side wall and including a collar adapted for slidable engagement with the side wall. The relationship of the device vis-a-vis the housing can be fixed in such a manner that the collar may at least partially obstruct the aperture so as to regulate the flow of seed therethrough. The device is preferably formed as an integral unit and includes a tray portion radially outwardly extending from the collar and terminating in an upstanding rim further provided with a plurality of radially extending circumferentially spaced perches. The aperture is preferably elongated and is positioned at an angle between 30 degrees and 60 degrees and preferably is about 3/8" wide and 1" long.
