Bird Egg
Bird eggs are laid by females and incubated for a time that varies according to the species; a single young hatches from each egg. Average clutch sizes range from one (as in condors) to about 17 (the Grey Partridge). Some birds lay eggs even when not fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs.

Famous quotes containing the words bird and/or egg:
“With a broad shoehorn
I am unstuffing a big bird in this dream
Msomebody else’s holiday feast—
and repacking the crop of my own,
knowing it will burst with such
onion, oyster, savory bread crust.”
