Parent birds spend days finding a perfect location to lay their eggs and build nests.

You might have observed a house sparrow bring brown sticks to build the nest. Along with the twigs, it also gets some green leaves from a tree to create soft bedding for the egg in the nest.

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.

Baby sparrows will leave the nest made of twigs in 24 days and can fly in 35 days. The eggs laid by warblers are not all the same. Many eggs vary in size, shape, color, and weight.

What birds lay white eggs?

We have seen different colored eggs like pale blue eggs, blue-green eggs, and brown eggs. There are types of eggs like warbler eggs and speckled eggs.

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. These are the birds that lay white eggs without any markings. Many bird species can lay white eggs, but their color often ranges from white to cream and has markings.

What bird eggs are small and white?

Birds live and feed almost everywhere on earth. Out of 10,500 living bird species, you can only imagine the variety in the shapes and sizes of eggs that different species of birds lay. But which bird species lay eggs that are small and white? 

Hummingbirds are beautiful and colorful birds that attract our eyes with their unique colorful patterns. But that is not the only interesting thing about them.

Hummingbirds lay the smallest eggs than any other bird. Ruby-Throated Hummingbird lays only two eggs during each brood; that is, its clutch size is two.

They lay immaculate white eggs, sometimes the size of a pea. Other birds like Eurasian Collared Doves, House Sparrows, and American three-toed woodpeckers also lay pure white eggs, but the ones laid by Hummingbirds are the smallest in size compared to others.

White Bird Egg Markings

You might have observed that not all the birds' eggs look the same. They have distinct features like shiny, glossy shells or different freckles on the shell. Most eggs are not even white!

Markings or speckles are common on various birds' eggs. For example, a house sparrow's egg is greenish-white or white, but a cave swallow's egg is white but has fine reddish-brown or purple spots on its eggshell.

The egg of an American Kestrel, having a clutch size of four to five eggs, has a white to pale brown color and brown or gray spots or markings. A Goldfinch has a clutch size of five. A Goldfinch egg has pale brown markings on it.

White Bird Egg Size and Shape

White bird eggs are a type of bird eggs that can be used for breeding without further processing. They are white and have a similar size to that of a chicken. Their shape and size will help you identify them. However, you can also find them in sizes and shapes that differ from the average.

The largest egg-laying bird is the ostrich, and the eggs of an ostrich are the largest of all eggs. They are about 11.81 in (30cm) long and weigh about 5.5 lb (2.5 kg) each. The smallest bird egg is laid by the bee hummingbird.

This tiny bird weighs less than 1.05 oz (30 g), and its egg is only 0.11 in(3 mm) long. Warbler eggs are shaped differently. Some eggs are perfectly round, while others are shaped like a small oval.

What animal lays tiny white eggs?

Birds lay eggs one at a time in each clutch, and only the incubated ones are further hatched. Eggs vary in size. Did you know the fun fact? A single ostrich egg is used to make the world's biggest omelet. Not just birds; even animals lay white eggs. 

A skink is a type of lizard. It belongs to the Scincidae family, a group of lizards that lay eggs. When skinks are born, they are the size of a dime.

They are born with vitelline teeth, which are sharp, pointed teeth that are used to break out of their eggs. Skinks are born with these sharp teeth because they are carnivorous lizards. Other than a skink, snakes like King snakes and corn snakes lay tiny white eggs similar to birds' eggs.

How do you identify bird eggs?

Birds and nests go together like two peas in a pod. But these aren't just any birds and nests - these are specifically birds and nests for your garden. Have you found eggs in your garden and wondered whether they are bird eggs? Let's take a look at a simple identification technique.

The most common bird egg identification technique is to compare the bird egg with an animal egg. The bird egg is generally five to seven times bigger than an animal egg.

A bird eggshell is thinner than an animal egg. The bird egg has a distinctive shape that is different from the shape of an animal egg. It also has more distinctive markings than an animal egg.

Identify Bird Eggs By Color And Size

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.

The eggshell is made of calcium carbonate, calcium phosphate, and calcium sulfate. The eggshell is made to be stronger at the ends than in the middle.

What should you do if you find an abandoned white bird egg?

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.
