    Abstract: A bird feeder having an upstanding circular housing with a cone shaped floor, a plurality of openings arranged about a lower edge of the housing and a feed assembly, associated with each opening. The feed assembly comprises a collar mounting a spout and includes an extension arranged beneath the spout. The extension has a threaded bore which receives a threaded first end of a rod. The opposite end of the rod is vertically offset from the first end providing a perch. The rod is laterally adjustable by adjusting the position of the first end in the bore which positions the perch at variable distances horizontally of an outer end of the spout. The position of the perch relative to the spout determines the size birds the feeder may accommodate.
