Disclosed is a flying toy capable of moving by flapping of wings. The flying toy comprises a support structure; an actuation mechanism, for the wings, arranged on the support structure and comprising a crank drive rotated by a means providing the driving force; and two flexible wings arranged symmetrically with respect to the vertical plane of symmetry of the toy and connected, at the wing bases, to the actuation mechanism, the aforementioned wing bases being mounted oscillating about axes arranged on both sides of the vertical plane of symmetry of the toy.
