Except around Easter, chicken eggs usually come in a predictable range of colors: white, brown, and sometimes pale blue or green. Chickens are descended from the Red Jungle Fowl of Southeast Asia, which has been providing eggs for humans for thousands of years. The final color of an egg comes from a pigment the hen’s body adds to the shell just before the egg is laid. Breeds that lay white eggs do...

Piping Plovers are tiny, sand-colored shorebirds that nest on the beach. They’re threatened in much of their range. But plovers have gotten a boost from something rather surprising: hurricanes. Superstorm Sandy left behind plant-free, sandy beaches on barrier islands in New York and New Jersey, which actually offers better camouflage for nesting plovers. Where these hurricane-created habitats were...

Although many seabirds utter groans and croaks, the Pigeon Guillemot produces a lovely series of trills and whistles. As part of their courtship, they fly side by side in large circles and loops, a perfectly synchronized flying act. These guillemots do not breed until they are between three and five years old. The male chooses a site in a crevice or cave, among boulders, under driftwood, on a whar...

Why are blackbirds black? One possible answer is that black is conspicuous against just about all of Nature's backgrounds. Blackbirds, like this flock of Red-winged Blackbirds and Yellow-headed Blackbirds, feed on the ground. Whenever a predator approaches, they take flight. Coming together quickly in a dense mass may confuse the predator and thwart its attempts to catch one of the birds. More inf...

Young birds leave their nests in different ways. Some shuffle tentatively along the nearest branch and practice flapping their wings, while others take the "big leap." Which path they take depends upon their species and the location of the nest. Young Great Horned Owls clamber out of the nest to nearby branches where they flap their wings and make short, cautious flights, while they continue to be...

Crested Auklets are small seabirds that nest on remote cliffs in the Northern Pacific and the Bering Sea. But it’s their smell that really sets these birds apart. They smell like tangerines! Experiments show that females go for males that emit the strongest scents. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter.

Some birds spend most of their lives on the open ocean, only coming to land when it's time to breed. These high-sea specialists are called pelagic birds, which include jaegers, petrels, and albatrosses, among many others. The best way to see them for yourself is by setting sail on a pelagic birding tour or whale watching cruise! More info and transcript at BirdNote.org . Want more BirdNote? Subscr...

David Sibley, creator and illustrator of The Sibley Guide to Birds , offers this advice for people learning to identify birds: “Spend time at home, paging through the field guide . . . by flipping through the pages of the book and looking at pictures and reading the names, you’ll start to get a sense of what those birds are . . . It doesn’t have to be about seeing a lot of different species, but m...

Names are conventions, right? But some names contain something special: a bird! For example, the name Paloma comes from the colloquial name in Spanish for the common pigeon, but as a human name it often refers to doves. Or Garzón, my last name, is derived from Garza, or Heron, in Spanish. Listen to this episode in Spanish here .  More info and transcript at BirdNote.org . Want more BirdNote? Subsc...

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 begin their southbound migration, without their young. Juveniles don't migrate with their parents, but wait a mo...

Crows play many roles in human cultures, from ominous tricksters to sacred purveyors of wisdom. After exploring the stories behind her family surname, attorney and playwright Alice T. Crowe discovered a deep historical connection between the racist symbology of Jim Crow and the negative image of these birds in many Western cultures. Despite the social stigma surrounding crows, Alice says we can le...

If you see a wild bird with a small metal band around its leg, that means researchers have given the bird a unique ID to keep track of it over the course of its life. You can report the sighting to the Bird Banding Laboratory, a part of the U.S. Geological Survey that studies banded birds across the continent. Analyzing where and when banded birds are seen helps biologists figure out bird lifespan...

In 2022, ornithologists recognized the Chihuahuan Meadowlark as a separate species rather than a subspecies of the Eastern Meadowlark. Named after the northern region of Mexico where they're easy to find, Chihuahuan Meadowlarks live in dry desert grasslands. They form a distinct population in Mexico and the southwestern U.S., and have a song that sets them apart from other meadowlarks. Escuche est...

Adorned in shades of peridot green, sapphire blue, and onyx black, the Green Jay is a jewel-toned wonder with a voice as loud as its color palette. Their range is split over two regions, one from southern Texas to northern Belize and a second along the Andes Mountains from Venezuela to Bolivia. Green Jays often forage in family flocks where their noisy, rasping chatter helps ward off predators and...

The male hummingbird leaves the female to build the nest and raise the young alone, but other father birds are more involved. A Peregrine Falcon father shares duties almost evenly with the mother. (Stewart, pictured, nested on a Seattle skyscraper for many years.) But the male Emu of Australia tops them all. He remains alone on the nest for nearly two months, never leaving the nest for any reason....

Baby Bald Eagles have a lot to learn before they reach adulthood. While still in the nest, they practice fanning their wings and jumping into the air to test their strength. When they’re finally ready for their first test-flight, the fledglings sometimes land unceremoniously on the ground until a parent offers further encouragement. Juvenile Bald Eagles are roughly the same size as their parents,...

Nature has produced some exceptionally strange animals. One such creature is the Oilbird of northern South America. The Oilbird prefers a diet of wild berries and fruits, especially lipid-rich fruits like palm nuts and avocados (which leads to fatty young and the Oilbird's name). This unusual-looking bird is longer than a crow, with big eyes and a tiny bill protruding from a giant mouth. Oilbirds...

The ancient Greeks believed the gods turned two distraught lovers into kingfishers — or “halcyon birds.” Thanks to divine assistance, these birds would enjoy calm weather during their nesting period. Even today, many kingfishers have echoes of this story in their scientific names. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter.

Grackles are notoriously loud and brazen birds. For all six species native to the Americas, males are iridescent black and females are sumptuous brown. Though these grackles may look the same, they each make their own distinctive ruckus. Though some deem them pests, grackles can also call us to celebrate the delightful diversity of “common” birds.

The Hoatzin is a strange bird, indeed! It looks like it was put together by a committee. But the way it looks isn't the only thing that sets this bird apart. The Hoatzin is strictly a leaf-eater, filling its stomach with leaves, and then resting and digesting for long periods. Chicks have vestigial claws on their wings, which they lose when they grow older. Listen to this episode in Spanish.  More...

High in the mountains of Chiapas, the southernmost state of Mexico, a male Highland Guan is performing his territorial display. The Highland Guan perches on a tree-branch, whistles, and then glides on vibrating wings. The resulting wondrous sound is like no other. The bird’s display creates a sound emblematic of the cloud forest of El Triunfo Biosphere Reserve. Clouds and fog roll frequently throu...

To get a good look, first try listening for their unmistakable vocal feats! This episode is sponsored by Gary and Liz Kennedy Ketcheson, who are grateful to BirdNote for introducing us to wonderful stories about b...

The feathers of a bird are, for their weight, among the strongest structures in the world. The bones of this Magnificent Frigatebird weigh less than its feathers! To further reduce weight while maintaining strength, many bird bones are fused. In addition, the pectoral and pelvic girdles and ribs are joined to make a rigid box that supports those long wings, just as the wings support the bird. More...
