ABSTRACT:
An improved depending bird feeder container, having a dung shield suspended over the bird feeder container and having the container formed to a special shape, similar to a "bell" shaped substantially cylindrical walled housing or container of a specific minimum diameter at the top or suspended portion of the container and a flare of a minimum length. This shape defeats squirrels and similar animals from climbing down the outside of the feeder container.
