SPECIES-SELECTIVE BIRD FEEDER

Abstract

The species-selective bird feeder is a bird feeder with a feeding tray that is selectively coverable to only provide access thereto by particular bird species. The species-selective bird feeder includes a support, a feeding tray mounted on an upper end of the support, and a bird feed dispensing hopper supported on the feeding tray. An additional cage is provided for selectively covering the feeding tray. The cage includes at least one sidewall and an open lower end. The cage is vertically adjustable with respect to the support and the feeding tray, such that, in a raised position of the cage, the feeding tray is freely accessible to birds and, in a lowered position, the feeding tray is only accessible through the open lower end of the cage. In the lowered position, the open lower end of the cage is positioned beneath the feeding tray.

DETAILED DESCRIPTION

[0014] The species-selective bird feeder 10 is a bird feeder with a feeding tray 14 that is selectively coverable to only provide access thereto by particular bird species, such as those with zygodactyl feet as a non-limiting example. As shown in FIGS. 1A, 1B and 2, the species-selective bird feeder 10 includes a support 12, a feeding tray 14 mounted on an upper end 16 of the support 12, and a bird feed dispensing hopper 18 supported on the feeding tray 14. A cover 36 may be provided for releasably covering an open upper end of the bird feed dispensing hopper 18. As is conventionally known, the bird feed dispensing hopper 18 has openings or apertures to dispense bird feed into the feeding tray 14. It should be understood that any suitable type of dispensing arrangement may be provided for dispensing the bird feed from the hopper 18 to the feeding tray 14. One example of such a dispensing hopper/tray arrangement is shown in U.S. Pat. No. 5,791,286, issued to Taussig et al., which is hereby incorporated by reference in its entirety. In FIGS. 1A and 1B, feeding tray 14 and bird feed dispensing hopper 18 are shown formed from a transparent material, such as transparent plastic. However, it should be understood that the transparent feeding tray 14 and bird feed dispensing hopper 18 are shown for exemplary purposes only, and that feeding tray 14 and bird feed dispensing hopper 18 may be formed from any suitable material.

[0015] In the non-limiting example of FIGS. 1A, 1B and 2, the feeding tray 14 is shown as being substantially circular, the bird feed dispensing hopper 18 is shown as having a substantially frustoconical contour, and the cover 36 is shown as having a substantially conical contour. It should be understood that the shapes, sizes, relative dimensions and overall configurations of each of the support 12, feeding tray 14, bird feed dispensing hopper 18 and cover 36 are shown for exemplary purposes only.

[0016] A cage 22 is provided for selectively covering the feeding tray 14. The cage 22 includes at least one sidewall and an open lower end 24. In the non-limiting example of FIGS. 1A, 1B and 2, the cage 22 is shown as being cylindrical and sized to loosely seal around the lower end of the conical cover 36. However, it should be understood that the shape and relative dimensions of cage 22 are shown for exemplary purposes only, and that cage 22 may be manufactured in a variety of different sizes and shapes dependent upon the particular type of overall bird feeder which cage 22 is intended to cover. As best seen in FIGS. 1A and 1B, cage 22 may have an open upper end 38 to accommodate cover 36. However, as noted above, the overall configuration of cage 22 is shown for exemplary purposes only and may be varied.

[0017] The cage 22 is vertically adjustable with respect to the support 12 and the feeding tray 14, such that, in the raised position of FIG. 1A, the feeding tray 14 is freely accessible to all birds and, in the lowered position of FIG. 1B, the feeding tray 14 is only accessible through the open lower end 24 of cage 22. In the lowered position of FIG. 1B, the open lower end 24 of cage 22 is positioned beneath the feeding tray 14. Thus, in the lowered position, only birds with, for example, zygodactyl feet (e.g., monk parakeets and rose-ringed parakeets), would be able to enter the cage 22 through the open lower end 24 to access the feeding tray 14, since the zygodactyl feet would allow these birds to grip the bottom end of the cage 22 to maneuver inside.

[0018] As shown in FIGS. 3A and 3B, an additional barrier may be provided to make it even more difficult for a non-target species of bird to access the feeding tray 14 when the cage 22 is in the lowered position. A plurality of prongs 40 may be pivotally attached to the cage 22 adjacent the open lower end 24. In FIG. 3A, the prongs 40 are deployed, requiring a bird to carefully maneuver between prongs 40 to enter the cage 22. As noted above, only birds with zygodactyl feet, for example, would have the dexterity to be able to maneuver between prongs 40. As shown in FIG. 3B, the prongs 40 may be selectively folded into a collapsed or stowed configuration for when cage 22 is in the raised position.

[0019] In order to vertically adjust the cage 22 to selectively cover and uncover the feeding tray 14, at least one cage supporting member 26 is fixedly secured to the support 12. In FIGS. 1A, 1B and 2, four such cage supporting members 26 are shown, however, it should be understood that the four cage supporting members 26 are shown for exemplary purposes only, and that any suitable number may be used. The cage 22 is releasably attached to the cage supporting members 26 for vertically adjusting the cage 22 with respect to the cage supporting members 26. As a non-limiting example, the at least one cage supporting member 26 may include a mounting rod 20 and a mesh panel 32 mounted on a free end 28 thereof. The cage 22 may then be releasably attached to the mesh panel 32. Mesh panels 32 provide an additional gripping surface for the zygodactyl feet of the target species, as discussed above.

[0020] It should be understood that cage 22 and mesh panels 32 may be made from any suitable material with any suitable mesh size. As a non-limiting example, cage 22 and mesh panels 32 may be made from welded wire mesh coated with polyvinyl chloride (PVC), with a mesh size of approximately 2.54 cm.sup.2.

[0021] In FIGS. 1A and 1B, the cage 22 is shown releasably attached to mesh panels 32 by conventional cable ties 30, however, it should be understood that cable ties 30 are shown for exemplary purposes only and that mesh panels 32 may be releasably secured to cage 22 by any suitable type of releasable fixtures, such as clamps, ties, clips or the like. Further, in FIGS. 1A, 1B and 2, mounting rods 20 are shown as being substantially L-shaped (i.e., rods with bends which may be approximately 90°± any desired angular deviation, and with a bend which may be rounded, as shown). It should be understood that substantially L-shaped mounting rods 20 are shown for exemplary purposes only, and that mounting rods 20 may have any suitable contouring or relative dimensions. Further, it should be understood that the cage supporting members 26 are shown for exemplary purposes only and are not limited to the combination of mounting rods 20 and mesh panels 32. Cage supporting members 26 may have any construction suitable for the releasable attachment of cage 22 thereto.

[0022] The species-selective bird feeder 10 may further include a feed-catching tray 34 mounted on the support 12 beneath the feeding tray 14 for catching any bird feed which accidentally spills from the feeding tray 14. It should be understood that feed-catching tray 34 is shown in FIGS. 1A and 1B for exemplary purposes only and may have any suitable contouring and relative dimensions. It should be further understood that the species-selective bird feeder 10 may include any other type of accessories commonly associated with bird feeders and the like.

[0023] It is to be understood that the species-selective bird feeder is not limited to the specific embodiments described above, but encompasses any and all embodiments within the scope of the generic language of the following claims enabled by the embodiments described herein, or otherwise shown in the drawings or described above in terms sufficient to enable one of ordinary skill in the art to make and use the claimed subject matter.
