An ornithopter toy (1) comprises a body (2) having a front end (3). a rear end (4) and two opposing sides (5, 6). The toy (1) also has two pairs of wings (13, 14) wherein the wings (13a, 13b, 14a, 14b) of each pair (13, 14) extend outwardly from the respective sides (5, 6) of the body (2). A drive mechanism (8) provides flapping movement of the wings (13a. 13b, 14a, 14b). One wing (13a, 14a) of each pair (13, 14) has a surface area that is larger than the surface area of the other wing (13b, 14b) of the pair (13, 14). |
