Abstract
A protective guard for a bird feeder is provided. The protective guard includes a substantially dome-shaped main body with a concave inner side, a convex outer side and an apex region. The main body includes a wire hanger receiving slot through the apex region of the main body. A circular wall downwardly depends from the concave inner side of the main body. The circular wall is located to surround the wire hanger receiving slot and is dimensioned to have a diameter slightly larger than the diameter of a top cap of a bird feeder. The guard may be readily placed over and installed on a bird feeder by inserting a wire hanger of the bird feeder through the wire hanger receiving slot with the concave inner side of the main body resting on the upper surface of the top cap of the bird feeder thereby retrofitting the protective guard thereto. In addition, the guard may be connected to the bottom of a post mounted bird feeder to provide a squirrel baffle.
