Abstract
The Castle Birdfeeder provides an efficient method for feeding wild birds and conserving bird seed. The device may comprise a birdfeeder shaped like a castle containing removable components. The base of the invention can be a rectangular and one-quarter inch deep to hold water, be used as a moat, in which birds can drink, clean and cool themselves. The castle may include perch doors on each side that fold up and down like a castle door. Birds can stand on these perch doors while poking their beaks through the round windows in the castle side to access seed contained in a seed holder made to fit within the dimensions of the castle. As birds eat, any excess seeds may fall from the seed holder to the seed catcher placed directly below. The design of this invention may also prevent squirrels and other animals from accessing and stealing bird food.
