The most common type of warblers in the United States are sparrows. A house sparrow has a clutch size of four to five eggs. These small brown and white birds are found in backyards, parks, and farms all over the country.

Sparrows build their nests in the spring and lay an average of four-five white eggs. Baby sparrows or sparrow chicks will hatch in nine to twelve days, and they will be fully feathered in two weeks.

Some birds lay white eggs. To keep away from the predators, the parent birds build their nest high up on the trees keeping a perfect location to avoid predators like snakes, rats, or mustelids.

Even though white, there are types of white eggs that birds lay. Some birds lay their eggs which have speckles. These are called speckled eggs.

Some birds lay their eggs with a slightly glossy eggshell. There are very few warblers that lay extremely pure and perfect white eggs.

Some of the birds that lay plain white eggs are the Eurasian collared-dove, tree swallow, American three-toed woodpecker, oak tit mousebird, blue-throated hummingbird, and the Purple Martin.

A Robin is undoubtedly famous for its singing. Robins have a clutch size of five to six eggs. Are you aware that Robin's egg is not white? The egg's color has nothing to do with the bird's color. A Robin has blue-green eggs or pale blue eggs due to biliverdin, a pigment deposited when a female Robin lays eggs.

 A few species of birds like the mourning dove and the white-eye only lay white eggs. Some birds like the pigeon and the ostrich lay eggs in a whole range of colors.

The color of the shell is decided by the species and not by the color of the bird. The blue-footed booby has blue or slightly pale blue eggs and can even be seen by the naked eye. The eggs of the kiwi are also blue.

The eggs of some species like the ostrich and the emu are reddish-brown. The eggs of some species like the avocets are bright yellow. Eggs are the only living cells of the bird outside of its body.

A Dunnock is a bird that lays eggs in nests, usually on grass. A Dunnock lays sky blue eggs, whereas a blackbird's eggs are glossy, smooth, and blue. The eggs of a blackbird have green or brown freckles. But what to do after you have identified an abandoned bird egg in your garden?

If you find an abandoned white bird egg, it is most likely that the mother bird has abandoned it for one of the three reasons; the egg is infertile, the mother bird was harmed, or she has a new clutch of eggs.

If you find an abandoned egg, the first thing you should do is find its nest, which is most probably on a tree closer to the area in which you found the egg.

After you find the nest, compare the other eggs with the one you have found and if it is the same, place it in the nest and move away as quickly as possible. This is because you wouldn't want to scare its parent birds.

You cannot bring the egg home as it is illegal, and you require a permit.

If you wish to see the egg hatching, monitor the nest in the coming days, and you may get a glimpse of it.
