The present invention is 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.

A bird feeder has a body member, a base, and at least one feed port member. The body member is used for storing bird food having a top end, a bottom end and a sidewall with the sidewall of the body member defining at least one feeding aperture. A base is attached to the bottom end of the body member to prevent bird food from exiting the body member. The at least one feed port member is interfittingly engaged within at least one feeding aperture. The port member includes a frame member and a mesh insert attached to the frame member. The feed port member is releasably secured within the feeding aperture of the body member. In operation, the feed port member can be easily removed from the body member for easy cleaning or adapting to a particular bird feeder construction.

A nectar feeder for hummingbirds is disclosed. The feeder includes a container configured and arranged to store nectar feed. The container has a top end and a bottom end. A spout depends from the bottom end of the container with an exit port defined thereon. A base tray positioned below the container. The base tray is further configured and arranged to contain nectar feed therein. A vertical member extends from the base tray. A float is positioned between the container and the base tray. The float engages the vertical member to prevent substantial independent lateral movement of the float within the base tray. The float carries a stopper with a substantially flush surface 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.

The present invention provides novel apparatus for aerating a body of liquid. The apparatus includes a diffuser shell in the form of a substantially tubular, elongate body of a relatively rigid, gas permeable material such as fine pore polyethylene. The diffuser is closed at one end by a first end cap and at the other end by a combination second end cap and gas inlet assembly. The latter is adapted for connection to a source of pressurized gas. Disposed within the hollow interior of the diffuser shell is an elongate housing for containing a suitable ballast. The diffuser shell and ballast housing are dimensioned so that there is an interspace between the external periphery of the ballast housing and the inside of the diffuser shell. The ballast housing is supported at one end by the first end cap, and at the other end by the second end cap and inlet assembly so as to maintain the interspace between the ballast housing and the diffuser shell. Conduit means are used to connect a source of pressurized gas to the inlet assembly.

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.
