International ClassA01K 039/01AbstractThe present invention provides a bird feeder with a height adjustment to allow the bird feeder to be lowered for gaining access thereto. A slide member is attached to the bird seed tray which slides up and down a support for lowering the bird feeder into a lowered position and elevating the bird feeder into an elevated position for dispensing bird seed therefrom. A deflector is provided for directing the bird seed onto the tray for dispensing thereof. A spiral shaped wire is placed upon the feeding portion of the tray in order to prevent the birds from kicking out the bird seed from the tray onto the ground. A protective cover covers the bird feeder to protect the bird seed from the weather. | |
