bird egg
Nest's fragile contents
A bird egg is the reproductive body laid by female birds, consisting of a protective shell encasing the embryo and its nutrients.
The term distinguishes eggs laid by birds from those of other animals—reptiles, fish, insects.
In casual speech, egg alone usually means a bird egg, especially a chicken egg: I'll have two eggs for breakfast.
Bird eggs vary enormously in size, from hummingbird to ostrich.
