Abstract: Disclosed herein is a bird feeder with a guard protecting against contamination of the bird feed contained within the feeder. The feeder comprises a housing that defines a feed chamber. This housing includes a lid, wherein the lid has at least one opening. This opening can be used by birds to access food within the feeder. As mentioned above, the feeder includes a guard. This guard is formed integrally or it can be a separate part attached to the lid near or at an opening. In one aspect, the guard includes an occluding element, wherein this occluding element is in communication with a biasing element. The occluding element has a first position which occludes an opening sufficiently to prevent animals other than certain birds from gaining access to said feed chamber. This occluding element is capable of being movable to a second position by applied external pressure to the occluding element thus permitting access to said chamber.

Abstract: Disclosed herein is a bird feeder comprising one or more tube chambers, a base, top locking device and a guard. This bird feeder allows a consumer to create multiple designs. For example, the guard of the current invention can be formed by one or more units adjacently disposed upon the feeder. The guard is ostensibly designed to prevent squirrels and other animals from accessing the feed chambers and can be configured in many different ways.

Abstract: A device for squirrel-proofing bird feeders includes a flexible covering sheet mounted above or to the upper end of the bird feeder. The sheet is dimensioned and located with respect to the feeder so that when a squirrel attempts to walk on the sheet, the sheet will flex and bend downwardly under the influence of the squirrel's weight. The squirrel will slide off the sheet and with no means or opportunity to grab onto any portion of the sheet or the feeder which it covers.

Abstract: A bird feeding device is provided with a perch which can be adjustably positioned with respect to the feeding opening to selectively accommodate different sizes of birds. The perch is movable toward and away from the feeding opening so that for larger birds the perch is positioned farther from the feeding opening than for smaller birds. The disclosed embodiment also includes a simultaneous heightwise adjustment for the position of the perch so that it is lowered when in its more extended position. Also disclosed is an improved arrangement for attaching the perch and feeding device to the container of the bird feeder. Another aspect of the invention relates to a bird feeder having a storage and feeding tube which is detachably connected to an overhead support by a quick disconnect device which provides for quick and simplified filling of the feed tubes as well as an arrangement which minimizes spilling or loss of bird seed.
