Difference between Ayes and Mammals
1. In ayes, most birds have feathers and they possess a beak. Mammals do not have feathers and the beak is also absent.
2. Ayes lay eggs, hence, they are oviparous. Some of the mammals lay eggs and some give birth to young ones; hence, they are both oviparous and viviparous.
