Quizplus · Accepted Answer

Snakes and birds both lay amniotic eggs, which are characteristic of reptiles and birds. However, while snakes are ectothermic, or cold-blooded, birds are endothermic, or warm-blooded. The presence of only a single ovary in females is a characteristic of some groups of animals, such as crocodiles and some birds, but not all snakes and birds share this trait.
