摘要:
A saving device for bird houses, feeders and feed is provided that includes a vertical member secured in an anchor medium topped by a pulley supporting a line able to be fastened by a cleat. The line attached to a sleeve traveling up and down the vertical member, by the action of an operator, is fitted with hooks to support feeders and houses for target species, protected by a guard and hanger clamp assembly, a means to hinder non-target animals from accessing and destroying feeders and houses for target species.
