Ruby-Throated Hummingbirds lay 2 eggs in each clutch, which is impressive considering the total volume of their eggs is quite large in relation to their body size.

These birds are remarkable incubators, with the females building and incubating the eggs in cup-shaped nests.

Their eggs are immaculate white, but cleverly hidden from predators by being nestled deep within the nest.

Nests are built in a way that makes it difficult for predators to spot the eggs, unless they're standing directly above the nest.

The American Robin is a sure sign that spring has arrived in North America. Its bright blue-green eggs in a mud-lined nest are a clear indication of the season.

The American Robin typically lays 3 to 4 eggs in its clutch. Many eggs don't make it to hatching due to predators like squirrels, snakes, and crows.

The Northern Cardinal is a stunning bird species, known for its bright red plumage. Its eggs, on the other hand, have a beige base color and brown spots.

The female Northern Cardinal builds the nest, constructing the base by crushing twigs with her powerful beak. She's a skilled builder, and her hard work pays off as she lays 2 to 4 eggs at a time.

The female Northern Cardinal is also responsible for incubating the eggs, while the male provides her with nuptial feedings. He follows her around, bringing her food as she tends to their eggs.

Cedar Waxwing eggs are a pale bluish gray with darker, delicate spotting patterns.

Both parents of the Cedar Waxwing play a crucial role in building the nest, incubating the eggs, and feeding the nestlings.

A clutch size of 4 to 6 eggs is typical for Cedar Waxwings, which time their egg laying with late-ripening fruit.

The parents of the Cedar Waxwing have a tight pair bond, which is essential for their breeding and parenting efforts.

Osprey are fascinating birds that are known for their impressive nesting habits. They typically lay 1 to 4 eggs per clutch.

It takes an osprey around five weeks to complete the incubation period for their eggs, which are dark blotch-covered. Osprey often reuse and improve their nests from previous years, making them bulkier and presumably safer for incubating eggs.

The Black-Capped Chickadee is a fascinating bird species.

Their eggs are white with small reddish-brown spots.

Clutch size typically ranges from 6 to 8 eggs.

These cavity-nesting birds prefer to breed in old woodpecker holes or rotting stumps, but not in artificial nest boxes.

This preference for natural habitats means they often face competition with other cavity-nesting birds for the limited available holes.

As a result, many chickadee embryos are sired by males other than the social father, a phenomenon known as extra-pair paternity.

Chaffinches are easily distinguished by their white wing-bar. Their eggs are usually laid in spring from around April.

The eggs are described as off-white with brown-red splotches.

Chaffinch eggs are relatively small, measuring 1.9 x 1.5 cm in size.

A typical clutch size for Chaffinches is 4-5 eggs.

Ground-nesting birds like lapwings often choose open areas for their nests to spot predators approaching. This helps them stay safe and protected.

Birds with larger clutch sizes may also have more elaborate nesting habits. The clutch size of 3-6 eggs, seen in some bird species, often results in more intricate nests made from twigs, bones, and other materials.

During nesting season, which typically falls in April and May, many bird species are busy building their homes and laying eggs. The carrion crow's eggs, for instance, are a beautiful pale blue-green color and speckled with dark brown and grey streaks.
