摘要：
A liquid bird feeder provides a liquid container having a sealable top opening and a bottleneck extension at its other end, and a liquid tray having a well adapted to receive the bottleneck extension and at least one feeding port. The sidewall of the well is provided with at least one drain hole and the sidewall of the bottleneck extension with at least one port. The container and bottleneck extension are rotatable within the well to selectively align and misalign the port with the well drain hole to respectively open and close the drain hole upon rotation of the container. In an alternate embodiment, the bottleneck extension is fitted with a collar rotatable with the container. The collar is received in the liquid tray well and includes at least one port. A liquid flow path is formed in the liquid tray for each feeding port to reduce the volume of nectar in the tray at any given time.
