摘要:
The nectar bird feeder, which has improved stabilization, includes a base with a bottom surface, a central portion, and a trough-shaped reservoir positioned about the central portion for containing nectar therein. A hanger is connected to the central portion of the base and extends upwardly therefrom. An extension stabilizing member is connected to the base and downwardly depends therefrom, such as from the bottom surface of the base. An annular-shaped cover, having a top surface and lower edges, is releasably attached to the base and co-extensive with the trough of the base with an aperture therein. The center of gravity of the feeder, with the stabilizing member, is located below the bottom surface of the base for improved stabilization thereof during filling and use of the feeder.
