麻豆约拍

Animals move in many different ways. Some birds fly whereas others do not, so how do we know when a bird is a bird? We meet a lady who works at an ostrich farm. She shows us the features of the ostrich, explaining why it looks the way it does, and the purpose of each feature (eyes on the side of its head, large feathers, and bare patches of skin). It is explained why the ostrich is definitely a bird, despite the fact it cannot fly.
