Abstract
Birdcage attachments are mountable to a birdcage and present a bird with a variety of interesting and challenging activities. The toy attachments encourage birds to learn by experimenting. As a bird manipulates some parts of the toy attachments, the bird will discover that the parts may be put into different positions and remain there until deciding to move them again. In most cases, the parts will not automatically return to their original state or position if the bird stops playing, challenging a bird even more to return the toy to its original state.
