Abstract
A nectar feeder for hummingbirds comprises a container, base tray, a base tray cover, a float, and a stopper thereon. The container, or bottle, is used for storing nectar feed. An exit port is defined on the bottom end of the container. The base tray is connected in fluid communication with the container and has at least one vertical member depending upwardly from a top surface of the base tray. A circumferential flange or ring is provided about the float for stabilization. The float engages the at least one vertical member to prevent substantial independent lateral movement of the float. In operation, the nectar feed flows through the container and into the base tray until the float rises to a level where the stopper mechanism engages the exit port to prevent fluid from flowing into the base tray.
