Abstract
A nectar feeder for birds. The nectar feeder has a container for storing nectar feed. A base tray is attached to the container and connected in fluid communication with the container. A float is positioned between the container and the base tray. A ball is positioned on the float. The ball regulates the fluid communication 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 where the ball prevents fluid from flowing into the base tray.
