Abstract: Unattached weights, namely: balls, which are confined and obscured in a housing, are lifted by inner ends of pivotably mounted perches in response to an undesirable, rapacious, and weighty bird, or squirrel, alighting upon, or clasping at the outer, extending portions of the perches. The ball-lifting, perch ends are cradles, and the cradles and balls define a relative, rolling friction therebetween which, in cooperation with a mechanical advantage of the extending portion of the perches vis-a-vis the cradles, demonstrate a diminishing resistance as the perches rotate downwardly and dislodge the unwelcome creature.

Abstract: A cylindrical-body bird feeder has an open bottom with a pair of cut-outs on opposite sides of the bottom. Slits, extending from the cut-outs latchingly receive a flexible floor for the body. The floor is only latchingly secured in the bottom, to facilitate cleaning of the feeder. In one embodiment of the feeder, the floor is latchable in either one of two pairs of slits, to accommodate the feeding of small seeds, or the feeding of large seeds, via window apertures, or via open troughs below the windows.

Abstract: A windowed housing attracts an animal to feed confined with a feed reservoir, but a limb set across the window frustrates the animal's attempt to access the feed. Pawing or pulling at the obstructing limb rotates a rod which opens a feed gate to discharge the feed into an underlying feed chamber. An opening in the chamber gives the animal access to the discharged feed, but release of the limb, to access the chamber-received feed, allows the feed gate to close.
