Abstract
A nectar feeder for hummingbirds is disclosed. The feeder includes a container configured and arranged to store nectar feed. A spout depends from the bottom end of the container with an exit port defined thereon. A base tray positioned below the container and contains nectar feed. A vertical member extends from the base tray. A float engages at least one vertical member to prevent substantial independent lateral movement of the float within the base tray. The float also includes a rounded bottom surface to further help stabilize it on the liquid feed to prevent leaking. The float has a stopper therein positioned below the spout. In operation, the nectar feed flows through the container and into the base tray until the float rises to a level where the stopper engages the exit port on the spout to prevent fluid from flowing into the base tray.
