The Little Bird Who Wanted to be a Motor (1973)

A bird obsessed with motors is attracted by the motor-like sound that insects make in flight and tries to imitate them. Seeing a plane, he perches on it blithely so that he can fly with a motor at last. But the plane has trouble and the pilot ends up taking an unwanted bath in the pond. That frees the bird of his obsession: he begins to fly naturally again and when a mosquito comes back to make fun of him, he gobbles him up.
