You’ve probably heard the old saying: “A bird in the hand is worth two in the bush.” Well, it’s a very old saying, and it’s gone through some changes over the years. In each era, the pragmatic wisdom is clear: Hold on to the sure thing rather than taking a gamble on something better. The saying even lent its name to a town in Pennsylvania!

In February, winter still holds sway over much of North America. But in Argentina, it’s summer, and birds are in full voice. Argentina’s national bird, the Rufous Hornero, belts out a rapid trill while the Rufous-bellied Thrush sings its lovely song. In the tropical forests of northeastern Argentina, a male Red-ruffed Fruitcrow, like the one pictured here, booms out its display calls. And the chee...

Millions of birds from around the world begin their lives in the Teshekpuk Wetlands of northern Alaska. In 2025, author and environment reporter Lynda Mapes visited the region to see how new fossil fuel developments are impacting wildlife in America’s Arctic. In this episode, Lynda recalls spending time with a family of Red-throated Loons. More info and transcript at BirdNote.org . Want more BirdN...

Birds have a highly efficient breathing anatomy that powers the exertion of flight. It is driven by large, thin-walled air sacs located throughout the body cavity that operate like bellows. This parabronchial system for extracting oxygen from the air has a far greater surface area than the lungs of a mammal, making sustained flight possible. This episode is brought to you by Wild Delight Bird Food...

Flocks of Cherry-headed Conures, a species native to South America, are now found throughout San Francisco. While a local legend claims that a pet shop owner introduced them by burning the shop down, it’s more likely that that a few of these loud-mouths exasperated their owners until they “accidentally” left a window open. Sadly, wild Cherry-headed Conures are falling ill from rodent poison. A non...

Black-footed Albatrosses are masters of the high seas, but their fate is threatened by trouble on land. At their nesting grounds on Midway Atoll in Hawai‘i, rising sea levels are washing away albatross nests and eggs. Since 2021, a research team led by Julio Hernández with the Grupo de Ecología y Conservación de Islas has been working to establish a new colony for of Black-footed Albatrosses on Is...

Black Rails are marsh-inhabiting birds, more often heard than seen. Many Black Rails nest in marshes along the Atlantic seaboard and in the Midwest. But in winter they concentrate in the coastal marshes of East Texas, Louisiana, and Florida, areas that face many threats. Sadly, according to the 2025 State of the Birds Report , Black Rail populations are perilously low and continue to decline. In r...

In parts of the United States, House Finches overlap with similar-looking Purple Finches. Their distinct songs help us sort them out. House Finch songs are jumbled and have a sharp, buzzy note — especially during the breeding season. Purple Finches’ songs, on the other hand, are smoother and lack the buzzy note. This episode is brought to you by Wild Delight Bird Food, which aims to support wild b...

Photographer Xavi Bou creates incredible images of birds and their movements by combining his love of photography and technology with his love for birds and nature — as seen in his book, Ornithographies. He’s especially drawn to European Starlings and their movements as a flock, called a murmuration. The starlings fly in a tight, synchronized group, sometimes to avoid a predator. ¡Este episodio es...

A forest in New Zealand rings with the sound of bellbirds, also known as Korimako or Makomako. Many bellbirds sing together, especially in the morning. Pairs sing duets. And a pair may counter-sing with its neighbors, perhaps letting them know that this patch of land is taken. It all builds to a brilliant, ringing dawn chorus.

No human dreams of relaxing on the shores of Novaya Zemlya, an archipelago in the Arctic Ocean that’s best known as a Soviet testing site for nuclear weapons. Yet, a growing flock of Pink-footed Geese have begun to make this militarized zone their summer home. Though this region was once too cold for the geese to raise young, climate change — and increased competition for food — may have made Nova...

It might sound strange, but dirt helps birds scrub themselves clean. Birds of all sizes, like the Eurasian Skylark, often scrape a depression in the ground and flick dirt onto their bodies, shimmying to shake it off. Experiments showed that birds use dust to prevent oils from building up on their feathers and to remove dandruff — much like humans using shampoo in the shower! More info and transcri...

Every summer, millions of birds flock to the Arctic Circle to find mates and raise their young. In a study published in 2025, paleontologists found evidence of the earliest known Arctic breeding colony from fossils uncovered in northern Alaska. The site dates back nearly 73 million years when many prehistoric predecessors to modern birds still had teeth; including the gull-like ichthyornitheans an...

In temperate climates like North America, it’s often male songbirds that sing the most. Typically the males migrate north before females and establish territories for the short breeding season, using their songs as a way to claim a spot. But many female birds do sing, even in colder climates (like this Bay Wren). And in warm tropic zones, female birds often have a big role in defending a territory...

If a bird’s feathers get too dried out, they become brittle. To prevent that from happening, most birds have a gland located above the base of the tail that produces oil. They use their beaks to massage oil from the gland into their feathers to keep them supple. A bird first grips a feather in its beak near the feather’s base. Then it slides its beak along the length of the feather toward the tip....

Birds’ four-chambered hearts run larger than those of mammals, relative to body size, and they are coupled with extremely efficient cardiovascular systems. The energy demands of flight require these adaptations. An exercising human has a heart rate around 150 beats per minute. In contrast, an active hummingbird’s heart pumps at 1,200 beats per minute; a flying pigeon’s heart beats at 600. More inf...

Magnificent Frigatebirds are huge, gangly seabirds found around the warm waters of the Western Hemisphere. When it comes time to mate, males inflate giant red throat sacs, then rattle and drum their bills against them to create jazzy percussive sounds. More info and transcript at BirdNote.org .

We've all heard that the early bird gets the worm. But research shows that birds dining early and heavily may lower their life expectancy. Socially dominant birds stay lean (and agile at avoiding predators) during the day, and then stoke up later, before a cold night. Subordinate birds have to look for food whenever and wherever they can find it, and carry fat on their bodies to hedge against unpr...

Urban ornithologist and children’s author Murry Burgess has always been interested in wildlife. But she first felt a spark for birds on a college field trip to Dauphin Island, a beach town on the Gulf Coast of Alabama that’s a famous stop-over site for migratory birds. There, she saw a dazzling male Painted Bunting that amazed her both with his colorful plumage and incredible migration journey. No...

Western Tanagers dart from tree to tree, on the lookout for delicious bugs. They’ll find them by scanning the tree bark — or maybe snatching them from mid-air during flight — a tactic called hawking. Come winter, these lovely songbirds head south, where they fit right in with the other brightly colored tropical birds they’ll spend the winter with in Mexico and Central America. More info and transc...

Ornate Hawk-Eagles stand out from other raptors with their impressive crest that looks like an elegant crown in adults, and a punk hairdo over the white-headed and black-bodied juveniles. These birds are excellent hunters, but they’re also devoted parents. ¡Escuche este episodio en BirdNote en Español! More info and transcript at BirdNote.org . Want more BirdNote?

While many birds have hollow bones that make flying a breeze, diving birds are built differently. The bones of divers such as Common Loons are denser than those of songbirds and other expert fliers. With a lightweight skeleton, they’d be too buoyant to dive and chase fish. Instead, loons can kick their powerful legs and webbed feet to swim 200 feet or more underwater!

Razorbills, a cousin to the puffin, nest in colonies on cliffs. Before they lay eggs, Razorbills take part in two unique social behaviors. In one, the Razorbills swim round and round in a tight mass, then dive as one. Next, they surface with heads aligned and bills held open. In another behavior, dozens of birds swim in a line, then zig-zag in a synchronized pattern across the ocean’s surface. Mor...
