Abstract
A birdcage feeding device is provided with a seed chamber, seed cup, and method of attachment. The feeding device comprises an opening that may be opened or closed in order to displace seeds from a feeding chamber to fill a seed cup. The seed cup is designed to be shallow such that seeds do not get buried under layers of empty shells and hulls. The seed cup also has high rear and side walls to guard seeds from being scattered outside by birds. The feeding device may be closed to allow a user to remove the seed cup, without removing the device, for cleaning. A method of attachment is also described that allows the device to be on the outside of the birdcage while being secured from the inside of the cage, thus allowing for easy refilling of the device.
