ABSTRACT:
A feeder apparatus wherein a counter-balanced perch is pivotally mounted adjacent a forward and rear face of the feeder structure, wherein the forward and rear face are mirror images relative to one another. The perch is pivotally mounted to trunnions orthogonally secured to side walls of the structure, with a counter-balance mounted thereon to permit adjustment of the feeder to accommodate and actuate to various classes of weighted birds mounting the perch. Upon a relatively large bird exceeding the support capacity of the perch alighting on the perch, the perch pivots downwardly and slidably draws a slide plate downwardly to prevent access of contents within the structure for feeding by the bird to discourage that category of bird from consuming feed within the organization.
