Snakes of the genera Dasypeltis and Elachistodon specialize in eating eggs. Humans have a long history of eating eggs, both wild bird eggs and farm-raised bird eggs. [citation needed] Brood parasitism occurs in birds when one species lays its eggs in the nest of another. In some cases, the host's eggs are removed or eaten by the female, or ...
Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell.
