A base is attached to the bottom end of the body member to prevent bird food from exiting the body member. The at least one feed port member is interfittingly engaged within at least one feeding aperture. The port member includes a frame member and a mesh insert attached to the frame member. The feed port member is releasably secured within the feeding aperture of the body member. In operation, the feed port member can be easily removed from the body member for easy cleaning or adapting to a particular bird feeder construction.
