Abstract: A birdhouse of cylindrical shape having circular end walls affixed in a detachable manner. Formed integrally with one of the end walls is a perch projecting outwardly from the end wall along a fold line. A perch support member is in abutting contact with the end wall and the perch. A retainer strip is struck from the end wall and the perch to confine the support member against dislodgment. A support strap for the birdhouse is provided with enlarged ends for inserted locking engagement with openings in each end wall.
