A bird feeder is provided with a metallic perforate trough bottom that is supported on its underside on ledges consisting of a plastic material on which water tends to bead rather than sheet, and which material is essentially self-lubricating and thereby non-caking and non-sticking. In its preferred form, the bottom is a screen that is slidable horizontally on the ledges. Preferably, the material is ultra-violet ray resistant and is therefore capable of long life in the outdoors, maintaining its desired characteristics for a considerable period. The end goal is to provide easy and quick feeder cleaning capabilities, especially in sub-freezing temperatures. The design prevents moisture-absorbent wooden elements of the feeder from coming into contact with screen.
