Abstract
The present invention is a nectar feeder for birds. The nectar feeder has a container for storing nectar feed. A base tray is connected in fluid communication with the container. A float is positioned between the container and the base tray. In operation, the nectar feed flows through the container and into the base tray until the float rises to a level to prevent fluid from flowing into the base tray.
