Only one of two to three Bald Eagle eggs generally survives to adulthood. After hatching, parents feed chicks constantly. The strongest eagle chick starves the others.
Cardinals have red feathers. Seeing a cardinal means deceased loved ones are with you. Cardinals lay 2-5 eggs at a time, and while it's unlikely that all will survive, merely one is rare.
Snakes generally deposit eggs. Nonvenomous colubrids, including kingsnakes and rat snakes, lay eggs. Elapids, such as cobras, are egg layers.
Most lizards lay eggs, not live young. Few lizards protect eggs. The mother builds a nest and leaves. So does the Komodo dragon.
Crocodiles lay eggs. They all make nests. Crocodiles excavate their nests in the sand or mud near the water's edge, whereas alligators and caimans make mounds of leaf litter and dirt.
Spiders lay eggs in massive webbing sacs. This protects them while eggs grow. They hatch all at once, and the spiderlings scatter to find a new home.
Humans can't see bee eggs. Eggs. Eggs. Each egg takes a few seconds, so a queen can lay 2,000 a day. Workers feed honeycomb larvae.
Largest bird lays largest egg. Ancient humans utilised the large, sturdy shells to hold water and cook meals. All ostrich females lay eggs in a communal nest.
