ABSTRACT:
A squirrel-proof bird feeder device with a metallic feed containment cavity having spaced and parallel side walls, a front wall spaced and parallel to a rear wall, a retaining plate attached to the inside of the front wall, a floor mounted perpendicular to and between these walls, and a movable roof which can be secured to the front wall with a latch. Nourishment flows through a gap between a retainer plate and the floor into a feeding cavity in the forward section of the feeder. An opening on the front wall exposes the feeding cavity and its contents. A fence created by the lower edge of the opening keeps the feed with the boundaries of the feeding cavity. A balancing perch assemblage having a wooden platform, a gate plate, a metal frame, and a metal bar that serves as a weight surrounds the front, side, and rear walls. This perch mounts to left and right supporters that pivot on respective left and right trunnions located on the lower sections of the side walls. The platform, the gate plate, and the weight are operationally associated to regulate access to the feeding cavity by having a feeding position and a non-feeding position, both determined by the weight of the bird sitting on the platform. The gate plate is substantially located inside the feeding cavity in an angular fashion to effect an open position in which permits access to the feeding cavity and a closed position which shuts the cavity.
