To hear a Common Loon in the wild during summer, you’ll need to find a northern, freshwater lake where a pair is nesting. But to find that same Common Loon in winter, you’ll likely need to look on a saltwater bay. This shift from fresh to salt water would kill most animals. But loons — along with many ducks and other water birds — have evolved to make that move. It’s possible that breeding adults...

The Wall of Birds at the Cornell Lab of Ornithology is a towering mural showing nearly 250 life-sized birds across a map of the world. To complete the impressive artwork, artist and scientific illustrator Jane Kim spent 17 months painting day in and day out. Though the experience was often solitary, Jane stayed connected to the outside world through the sounds of wildlife in the nature preserve th...

In the depths of winter, when open water is frozen over, it can be challenging for birds to stay hydrated. Some birds eat the frozen water all around them. Cedar Waxwings catch snowflakes in mid-air. Black-capped Chickadees drink from dripping icicles. Plenty of other birds scoop up fresh, powdery snow and eat it. It could be worth the calories to melt the snow when searching for liquid water coul...

Thomas Poulsom is a hobbyist LEGO builder best known for his models of birds. But making birds out of bricks isn't easy. That’s why he uses special pieces to sculpt something entirely different — like when minifigure carrots became a puffin’s legs. A unique piece called a “snot brick” allows him to build in any direction, making it possible to make a round object out of square LEGO bricks. More in...

At the visitor center of the Cornell Lab of Ornithology, artist and scientific illustrator Jane Kim painted the Wall of Birds to celebrate the evolution and diversity of birds. Completed in December 2015, the massive mural depicts nearly 250 birds — and several of their ancient predecessors — on a map of the world where each lives. Jane worked closely with scientific advisors to ensure that each p...

While many shorebirds have gone south, tiny sandpipers called Sanderlings are easy to find on winter shores. They follow the waves as they lap in and out, probing the swirling sand for prey. They often eat various small crustaceans such as mole crabs, isopods, and amphipods. But they also enjoy miniature clams, polychaete worms, and horseshoe crab eggs. They’ll even catch flying insects or eat pla...

Named for its rhythmic calls, the Black-legged Kittiwake is a dapper, oceanic gull. As described by Roger Tory Peterson, the tips of its pale gray wings "are cut straight across, as if they had been dipped in ink." Unlike many gulls, kittiwakes spend most of the year at sea and are seldom seen inland. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter...

The Andean Condor is one of the largest flying birds in the world. With a wingspan that can stretch over 10 feet across, the condor doesn’t flap so much as sail, using rising thermals to glide across the Andes for hours. Once revered in Inca mythology as a messenger of the gods, the Andean Condor now graces the coat of arms of Bolivia, Chile, Colombia, and Ecuador. But like many scavengers, condor...

Sandhill Crane families form a close bond. A pair of adults might travel north with their young from the previous summer, along with grown-up offspring from several years ago. After the breeding season, families will stick together for the journey south and the winter, even in large flocks. The parents often remain together for the rest of their lives.

Palmyra Atoll is a ring-shaped island encircling a lagoon in the South Pacific. The atoll lost many native trees due to U.S. military activity during World War II. Conservationists have worked to restore the ecosystem. Seabirds such as Black Noddies and Red-footed Boobies nest in the island’s rainforest. Their guano enriches the soil, and the soil’s nutrients help support the coral ecosystem that...

There are five million bird eggs stowed away in museums across the world — and the study of eggs, called oology, can give us great insight into birds. The link between DDT and the decline of Peregrine Falcon populations was identified in part using museum and personal egg collections, and this evidence helped lead to a ban on DDT. And today, Peregrines can still be seen zipping across the sky. Mor...

Kiwikiu, also known as Maui Parrotbill, used to be found all over Maui and Molokaʻi. Now, fewer than 150 individuals exist and kiwikiu are currently restricted to a tiny region of high elevation forest on the slopes of Haleakalā. A translocation effort to expand their range was unsuccessful due to the rapid spread of mosquito-borne avian malaria. More info and transcript at BirdNote.org . Want mor...

Yellow-eyed Juncos sometimes make a migration of sorts — not from north to south, but from the high mountains to the lowlands or the other way around. It’s called altitudinal migration. In the warm summer months, some Yellow-eyed Juncos prefer to nest at higher elevations. In winter, however, the scarcity of food pushes them back down to the valleys.

Isaiah Scott was in middle school when his family took him to visit the Cornell Lab of Ornithology. He remembers seeing a huge mural showing hundreds of colorful birds spread across a map of the world. That painting, called the Wall of Birds by Jane Kim, got Isaiah curious about how many of those species he might see for himself. In this episode, Isaiah shares how the artwork sparked his love of b...

Sometimes, a species’ song changes over the course of a few decades. But a bird that lives in the mountains of eastern Africa, the Forest Double-collared Sunbird, appears to have kept the same song for at least 500,000 years. That’s the amount of time that two populations of the species split up into two separate mountain ranges. Despite a lack of contact between those populations, they sing a nea...

When the air is thick with wildfire smoke, people are advised to stay home. At Hastings Natural History Preserve in California, Acorn Woodpeckers do the same. These gregarious birds live in family groups and frequently visit their neighbors while foraging. Using tiny radio transmitters, scientists tracked the movements of Acorn Woodpeckers during the summer of 2020 when wildfire smoke blanketed th...

A few times each year, the Eastern Paradise-Whydah puts on his party clothes. This small finch is found in East Africa, and males and females generally share the same nondescript appearance. But when it’s time to mate, the male sprouts extravagant, long, black tail feathers two or three times the length of his body. The feathers make it look like he’s wearing a long black cape, thus the nickname,...

Every summer, puffins — like this Horned Puffin — grow blazingly colorful layers over the bases of their huge beaks. But in the winter, puffins lead very different lives, and they shed their bright ornamentation. Puffins in winter are largely solitary — and silent. They spend about seven months alone at sea, before returning once again to their colonies to breed. More info and transcript at BirdNo...

Crane Hawks of Central and South America and African Harrier-Hawks both have legs that bend forward and backward. Each bird’s wonderfully peculiar leg adaptation is completely original — it evolved all on its own — even though the end result is the same. It's a fascinating example of a phenomenon called convergent evolution. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe...

Biodiversity conservationist Lily-Arison Rene de Roland works with some of the rarest birds in the world. He’s the Madagascar program director for the Peregrine Fund, a non-profit conservation organization that protects imperiled birds of prey like the Madagascar Fish-Eagle. These large raptors only eat fish, which means they rely on the same diminishing wetlands and natural resources as some fish...

Common Potoos are champions of camouflage. In the daytime these nocturnal creatures perch perfectly still on branches: heads pointed upward, bodies outstretched, and eyes closed down to tiny slits. It’s hard to tell where the branch ends and the bird’s body begins — which helps them avoid predators. They’re birds more often heard than seen; with a melodious but mournful song, made at dawn, dusk an...

Gyrfalcons are circumpolar , nesting in the far north of Asia, North America, and Europe, including Iceland and Greenland. They evolved as a distinct species in the Pleistocene Era, around 100,000 years ago. Their large size and warm feathering gave them an edge for nesting high in the Arctic. Gyrfalcons reuse the same nesting site year after year, and some nests have been occupied for 2,500 years...

Walk into the visitor center at the Cornell Lab of Ornithology and you’ll be greeted by a massive mural called the Wall of Birds. About the size of a tennis court, the mural shows a map of the world covered in 270 life-sized portraits of birds and their relatives — ranging in size from the 30-foot-long, feathered dinosaur Yutyrranus hauli to the tiny Marvelous Spatuletail hummingbird. Artist and s...

It’s early morning in Costa Rica. Tiny bats nestle in a tree after a night on the wing. A Great Kiskadee calls. Gray-capped Flycatchers sally forth from willow-like shrubs to catch insects in mid-air. White Ibis forage at the water's edge. Deep in a thicket, Black-hooded Antshrikes call. By noon, Chestnut-mandibled Toucans will shift lazily from one tree to another. In the evening, the sounds of c...
