For small songbirds, surviving a cold winter night can be challenging. Their bodies lose heat faster than those of larger birds. So little birds have found resourceful ways to stay warm — like huddling close together with other birds. But the Verdin, a tiny bird of the Southwest, does something few other birds do to keep warm: it builds extra nests…

Kentucky Warblers nest in forested regions in much of the East, preferring woodlands with a dense understory, often near streams or other wetlands. These birds can use our help. As their forest habitat shrinks, it’s easier for Brown-headed Cowbirds to find and parasitize the warblers’ nests. While

Kentucky Warblers nest in forested regions in much of the East, preferring woodlands with a dense understory, often near streams or other wetlands. These birds can use our help. As their forest habitat shrinks, it’s easier for Brown-headed Cowbirds to find and parasitize the warblers’ nests. While migrating, they are easy prey for domestic cats, so…

The two American species of dowitchers, Long-billed and Short-billed, are similar in appearance but have distinctive calls. And they’re some of the continent’s most dramatic songsters. On their northern breeding grounds, Short-billed Dowitchers ascend as high as 150 feet in the air then glide slowly

The two American species of dowitchers, Long-billed and Short-billed, are similar in appearance but have distinctive calls. And they’re some of the continent’s most dramatic songsters. On their northern breeding grounds, Short-billed Dowitchers ascend as high as 150 feet in the air then glide slowly earthward, singing. At the end of the glide, they…

The Greater Honeyguide's demanding call is not aimed at a member of its own species. Instead, the bird guides people in search of honey through the forest, directly to bee hives. The bird flies to a colony of bees living in a hollow tree. The human follower exposes the hive with an ax and takes much

The bird flies to a colony of bees living in a hollow tree. The human follower exposes the hive with an ax and takes much of the honeycomb. Then the honeyguide moves in to…

A typical bird nest will have maybe four to six eggs neatly arranged by the parent to hunker down on. But in one Rhea nest, you may find between 50 and 80 eggs! And they’re not all from the same set of parents. Male Rheas mate with several females and then build a single nest on the ground to hold

And they’re not all from the same set of parents. Male Rheas mate with several females and then build a single nest on the ground to hold all the eggs from each of them. Listen to this epis…

The Golden-headed Manakin is a tiny bird with dance moves that would turn a pop star green with envy. Johanne Ryan, a nature educator who lives in Trinidad, describes this bird’s remarkable breeding display, which features a moonwalk and tail-flicks.

Shorebird chicks hatch into a dangerous world, so they need to be vigilant from the start. Researchers in Australia noticed that some shorebird chicks began chirping in their final days in the egg. The chirps fell silent when the researchers played recordings of a Little Raven, which hunts for young

Shorebird chicks hatch into a dangerous world, so they need to be vigilant from the start. Researchers in Australia noticed that some shorebird chicks began chirping in their final days in the egg. The chirps fell silent when the researchers played recordings of a Little Raven, which hunts for young birds. The finding suggests the chicks are listen…

In an ornithology class in college, Corina Newsome was introduced to the Blue Jay. After this, Corina was determined to learn about the world of birds she had never noticed before. She went on to study avian ecology and now works in the field professionally, where she shares her passion with others.

Birds have to be smart to survive — but their minds often work a little differently than ours do. In a new study, researchers trained pigeons to identify different types of shapes, peck a button to give their answers, and receive a treat for the correct response. The pigeons learned to fix their mistakes over time, but not by learning their shapes …

Webbed feet are ideal for birds that swim, on the water’s surface or under. In fact, they’re such a nifty adaptation that they evolved, independently, in several bird groups. Ducks and geese, gulls, cormorants, loons, pelicans, penguins, puffins and boobies all have webbed feet.

Hidden below the outer breast feathers of herons, pigeons, doves, tinamous, bustards and some parrots are patches of special down feathers. These feathers are never molted, and they grow continuously. The tips break down into a dust the consistency of talcum powder. Using a fringed claw on its middle toe, a heron collects some of the dust — or powd…

Sailors once believed Wilson’s Storm-Petrels foretold a dangerous tempest. There might be a grain of truth: the tiny seabirds might find a little shelter from the gusts near a ship. Wilson’s Storm-Petrels are found in every ocean. When foraging, their feet patter across the surface, stirring up prey

The call of the Common Loon brings to mind a summer visit to northern lakes. A "yodel" call is given by a male on his breeding territory. With his neck outstretched, the male waves his head from side to side, sending his eerie calls across forests and open water. The yodel entices females and

The call of the Common Loon brings to mind a summer visit to northern lakes. A "yodel" call is given by a male on his breeding territory. With his neck outstretched, the male waves his head from side to side, sending his eerie calls across forests and open water. The yodel entices females and asserts a claim of territory. Nothing common about this …

Eared Grebes eat brine shrimp and aquatic insects for sustenance, but rigid exoskeletons make them hard to digest. So these grebes – along with their other grebe cousins – evolved to use their feathers as a way to slow down digestion. The feathers form dense balls in the digestive tract and appear to slow the passage of food long enough that the fo…

For some birds like hermit hummingbirds, the difference between sexes starts with the beak. Females hermit hummingbirds typically have curved bills while males wield straighter ones. Because the two sexes are better at drinking nectar from flowers that match their respective beak shape, males and females of the same species don’t compete with each …
