Describe how birds and reptiles both reproduce. describe two ways that birds and reptiles differ. use two particular animals as example in your description

They both produce eggs inside of shells, which contain the developing offspring.

After mating, the females of both groups produce eggs which envelope, nourish, and protect the developing offspring until they are ready to hatch. This is an adaptation that allows these groups to live their entire lives on land without having to return to the water in order to reproduce the way amphibians do.

All birds and most reptiles are oviparous, meaning that they lay their eggs outside of their bodies, in which the offspring develop until they hatch.

Some snakes are ovoviviparous, which means that after the mother produces the eggs, she retains the eggs until they hatch and she gives birth to live young. This is not the same as female mammals in which there is a uterus, an embryo, an amniotic sac, and a placenta.

Both birds, such as owls and eagles, and reptiles, such as snakes and lizards, reproduce with a unique kind of egg called the amniotic egg. An amniotic egg is a shelled egg in which an embryo develops. Birds are feathered and reptiles are scaled. Birds are endotherms (warm-blooded) and reptiles are ectotherms (cold-blooded).
