    Photo by John Weinstein Clutch size: 2 eggs A kiwi lays the largest egg in relation to its body size, but hummingbirds come in a close second when you add up the total volume of their two eggs laid in each clutch. Nests are built and eggs are incubated by the females. Like all hummingbirds, this species lays immaculate white eggs, but the eggs sit ...

    Photo by John Weinstein Clutch size: 3 to 4 eggs The spotless, bright blue-green eggs in the American robin’s mud-lined nest are a sure sign that spring has arrived in North America­—and sometimes they appear before the season itself.In places where trees are very sparse, robins may nest on the ground.

    Photo by John Weinstein Clutch size: 4 to 5 eggs Yellow warblers are popular targets of brood parasitic brown-headed cowbirds. When both species’ eggs are present in a nest, the warbler eggs often fail to hatch or the chicks might not make it to fledging. When cowbirds are near the nest, yellow warblers emit alarm calls and the female may sit on th...

    Photo by John Weinstein Clutch size: 2 to 7 eggs Blue jays swiftly remove sharp eggshell fragments to protect their newly hatched brood from harm. Discarding shells also helps prevent both microbial infestations and pungent-smelling cues that might alert nest predators about the location of the clutch. In this jay’s family, only the female incubate...

    Photo by John Weinstein Clutch size: 2 to 4 eggs The beige base color and brown spots of the Northern cardinal’s egg sharply contrast with the bright red plumage of the male parent.

    Photo by John Weinstein Clutch size: 4 to 6 eggs Erratic in their distribution and where they breed, cedar waxwings time their egg laying with late-ripening fruit. The waxwing egg is a balance of a pale bluish gray and a suite of darker, delicate spotting patterns. With a tight pair bond, both parents build the nest, incubate the eggs and, once the...

    Photos by John Weinstein Clutch size: 3 to 7 eggs The pale gray-blue Baltimore oriole egg is covered with sparsely distributed lines and squiggles that marble the egg. Occasionally, a nest may be attended by two birds that look like females. But usually one of them is actually a young male breeding for his first time, still displaying more cryptic ...

    Photo by John Weinstein Clutch size: 1 to 4 eggs It takes an osprey five weeks or so to complete the incubation period for its dark blotch-covered eggs. Older birds often pair with previous partners, reusing and improving the preceding year’s nestto build an even bulkier and presumably safer site for incubating the eggs. Ospreys sometimes nest in l...

    Photo by John Weinstein Clutch size: 6 to 8 eggs Chickadee eggs are white with small reddish-brown spots. The eggs of these cavity-nesting birds are rarely seen by most birders because the species does not usually choose artificial nest boxes. Instead, they prefer to breed in old woodpecker holes or in holes of rotting stumps. There is a trade-off,...

    Photo by John Weinstein Clutch size: 5 to 7 eggs Sandhill cranes lay relatively small eggs that are pale brown and marked with reddish brown blotches for camouflage. Both parents attend the nest and spend about a month taking turns incubating the eggs. But this is just a small fraction of their parental duties. They spend the next nine months looki...
