ABSTRACT:
The present invention generally relates to a bird feeder having an adjustable sealing feeding port. The feeding port may be moved from a first position to a second position with respect to the rest of the feeder. More specifically, the bird food may be secured within the bird feeder when the adjustable sealing feeding port is in the second position and the bird food may be accessible to birds while the adjustable sealing feeding port is the first position. The adjustable sealing feeding port may have a stopper made from, for example, plastic or rubber which may create a liquid tight seal with the body of the bird feeder.
