This invention relates to a toy bird, and more
particularly to such a bird of the ?ying or ?ap

A primary object of this invention is the pro
vision of an improved toy bird characterized by
movements of the wings simulating a bird in
?ight, which will afford pleasure in the ?ying
thereof, for both young and old ?iers.
Another object of the invention is the provision
of such a wing propelled type of toy which is 10
