In the Arctic National Wildlife Refuge, June days offer almost continuous daylight to breeding birds, including this Black-bellied Plover. At this high latitude, Black-bellied Plovers can complete their breeding cycle in a month and a half. Not long after the summer solstice, the adults…

Cliff Swallows gather in spring, in nesting colonies of up to 3,700 nests. Look for swarms of them under bridges, under the eaves of barns, or even the side of your house. The swallows use mud to make gourd-shaped nests - side by side and jumbled together. Watch the video! And Cliff…

Barn Swallows have adapted to nesting near people, and build their cup-shaped mud nests in barns or garages, or on protected ledges, often near each other. The good news? These twittery, flittery birds love to eat the insects that humans consider pesky. Imagine: 60 insects per hour, a…

The American Kestrel is the smallest, most numerous, and most widespread North American falcon. This bird is built for speed, its long pointed wings often bent back at the tip. While hunting, kestrels hover above an open field. These days, the lack of suitable nesting cavities, which…

The most distinctive characteristic of the California Quail is the black, forward-facing topknot that juts out from its forehead like a small flag. The California Quail – the state bird of California – builds its nest right on the ground. Almost immediately after hatching, the precocial…

The White-crowned Sparrow pours out its song over and over on spring and summer days-and even on moonlit nights-often up to 15 times a minute. Now here's a curious thing: Just as people in different regions may have different dialects, White-crowns have different songs, according to where…

When smaller birds join forces to ward off larger birds, it's called mobbing. This behavior — like calling your family for help — is used by many bird species. The best time to observe mobbing is spring and early summer, when breeding birds are trying to protect their nests and young…

Great Blue Herons nest in colonies, in adjoining trees or with several nests in one tree. But by autumn, the adults and gangly young have left the nests to take up solitary lives, a pattern that is the reverse of many other species. After all the "togetherness" of the nesting colonies, the…

The Canyon Wren makes its home on the steep rocky outcrops and vertical stone cliffs of the coulees and mesas of the West. The birds are found from Mexico all the way through southern British Columbia. They live among the rocks all year long, nesting in rock piles and beneath overhangs…
