Organized by the Cornell Lab of Ornithology, Project NestWatch is made up of volunteers around the world who monitor bird nests, reporting whether the birds successfully raise their young. Joining the project involves a bit of online training, finding a nearby bird nest, and briefly checking on it every 3-4 days without disturbing the birds.

Author and illustrator Becca Rowland likes to keep an eye out for cardinals. Her mom loves them and is pretty good at finding them, too. Becca didn’t know how she did it, until they realized their mom was birding by ear! Now Becca has written a new book called, Bird Talk: Hilariously Accurate Ways to Identify Birds by the Sounds They Make. More info and transcript at BirdNote.org. Want more BirdNote?

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 cheerful, bubbly notes of an Ultramarine Grosbeak remind us that spring in North America — and the arrival of birds like the Rose-breasted Grosbeak — isn’t too far off. ¡Escuche este episodio en BirdNote en Español!

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 BirdNote? Subscribe to our weekly newsletter.

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.

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 nonprofit, Mickaboo, adopts out healed rescues.  ¡Escuche este episodio en BirdNote en Español!

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 Isla Guadalupe in Mexico. Julio explains the island’s native Laysan Albatrosses are stepping in as “foster parents” to safeguard their Hawai’ian relatives. ¡Escuche este episodio en BirdNote en Español!

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 recent decades, the enactment of laws protecting wetlands has improved the bird's prospects. More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

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.

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 esta disponible en BirdNote en Español! More info and transcript at BirdNote.org. Want more BirdNote?

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 Novaya Zemlya a compelling alternative to their traditional territory in Svalbard. It’s also possible that the Pink-footed Geese found the archipelago by following other migratory waterfowl, which could prove to be a rare example of cultural knowledge being transmitted between species.

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!

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 and the flightless, loon-like hesperornitheans. These were among several types of ancient avians preserved as both adults and hatchlings, which suggests the site was used for nesting. Just like today, these birds were likely taking advantage of the abundant food provided by the 24-hours of summer daylight. More info and transcript at BirdNote.org. Want more BirdNote?
