Wings, Legs and Tails (1986) on Netflix

Plot summary

Under a scorching sun lies a desert that is nearly bare and lifeless, though lizards, insects and ostriches still live in it. A shy ostrich meets a vulture, who invites him to come along and promises plenty of tasty things wherever he is going. The ostrich agrees. The vulture flies and the ostrich runs along behind, which annoys the vulture, who says he told him to fly and not to run. Asked whether he has forgotten how, the ostrich admits he never learned. The vulture takes charge of the lessons, declaring that a bird who cannot fly will be taught, and one who will not be will be made to.
