发明名称 Bird feeder
摘要 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.
