Beavers are well known as ecosystem engineers in North America. In Australia, lyrebirds play a big role in shaping their environment when they use their toes to dig in the ground for food. A single lyrebird can shift 11 dump truck loads of soil and leaves — each year! That’s thought to be more than

For most birds, keen eyesight is critical for survival. But many birds lead lives that can be very hard on the eyes — like flying at breakneck speed, racing for cover into a dense thicket, or diving under water to capture prey. Imagine how the chips fly as this Pileated Woodpecker chisels a cavity

Nothing says summer like a day at the beach. Whether you’re lounging by a lake or enjoying a seaside vacation, listen to this episode to learn five things you can do to share the shore with birds. BirdNote is supported by Jim and Birte Falconer of Seattle, Washington — and generous listeners around

When they migrate, tiny songbirds that spend most of their lives on land fly hundreds of miles over the ocean at a stretch – and they get tired. Research suggests that birds migrating over busy shipping routes in the Mediterranean Sea may use the decks of sea vessels as places to catch their breath

Los zarapitos pico largo ( Numenius americanus) son las aves playeras más grandes de América del Norte. En su ritual de cortejo, el macho vuela trazando una serie de arcos en el cielo mientras emite sus llamados. Fuera de la temporada de reproducción, se posan y buscan alimento en parvadas mixtas

Why does the American Dipper dip? One possibility is that the dipper's repetitive bobbing, against a background of turbulent water, helps conceal the bird's image from predators. A second theory asserts that dipping helps the bird spot prey beneath the surface of the water. But this theory about why

Just off the southern coast of Iceland, the Westman Islands are home to many of the country’s several million Atlantic Puffins. When puffin hatchlings, known as pufflings, get confused by the lights of the city, volunteers of all ages search for wayward pufflings on the street and bring them in for

August 22 is the birthday of renowned French composer, Claude Debussy. Born in 1862, Debussy is known for his impressionistic sonic portraits, like La Mer, about the sea. But one of his best known works is an earlier piano piece, Clair de Lune. The song is quiet and haunting. Which got us thinking

Lark Buntings are migratory sparrows that live in grasslands from south central Canada to the northern plateaus of Mexico. For most of the year, the buntings are brown, white and streaky. They spend the winter traveling in large, nomadic flocks in search of seeds and insects. But as spring

Former Washington Governor Jay Inslee made the fight against climate change a major priority during his three terms in office. In this episode, Inslee explains how his love of birds helped motivate those efforts.

If you’ve already done things around the home with birds in mind, consider one more action that might be less obvious. Turning the thermostat down a degree or two in the colder months and up a degree in the warmer months might seem more about personal preference or energy bills than birds. But

El extraordinario órgano vocal que tienen la mayoría de las aves — la siringe — tiene dos lados, cada uno controlado por distintos músculos y nervios. Eso permite que algunas aves cantoras canten dos melodías distintas al mismo tiempo. El zorzal canelo ( Catharus fuscescens) incluso puede cantar una

Osprey are birds of prey with a wingspan more than 5 feet across. These large raptors construct huge stick nests that get up to 6 feet wide and 12 feet tall! While the Ospreys only occupy the upper portions of this structure, other birds have been observed taking up residence in the nooks and

Small, tern-like Bonaparte's Gulls often form a chorus-line at the water's edge. Side by side, in half an inch of water, they stomp their feet as fast as they can. Under this pummeling, a smorgasbord of shrimp is stirred up for the gulls to harvest. Is this a learned behavior, or were these gulls

During migration, some birds change orientation and travel almost the same distance — but in the opposite direction — as the rest of their species. The phenomenon is called misorientation. First-year birds are particularly susceptible. Many vagrant birds never find their way back on course, but some

By carrying more people in a single vehicle, mass transit can use less energy than cars. Taking steps to reduce greenhouse gas emissions can help the hundreds of bird species put at risk by climate change. Not to mention, you can do a little birding on the commute – on the way to the bus or train

Helmeted Guineafowl are known for moving in frantic flocks, often running and squawking about. In their native range – from Senegal to South Africa – these chicken-sized birds are favored prey of wild cats and Martial Eagles, so they need to be alert! Because they’re also spooked by unfamiliar

When a Northern Saw-whet Owl spreads its wings, many birds can see something our human eyes can’t: the owl’s flight feathers glow with ultraviolet light. It’s invisible to humans without the help of a UV blacklight. While the glowing feathers on parrots might help them attract mates, the reason for

Although American Crows may seem blasé about pillaging another bird's nest, they regard a threat to their own young as a punishable offense. To protect their nest, adult crows dive-bomb people, cats, other animals, and even other birds. Young crows fledge when they are around five or six weeks old

En un día caluroso de verano, observa con atención aves como el cuervo, o como esta águila cabeza blanca. Nunca los verás sudar, porque las aves no tienen glándulas sudoríparas. Entonces, ¿cómo se mantienen frescas? Una forma es jadeando. Cuando respiran con rapidez, el calor se expulsa del cuerpo a

Author Christian Cooper is never not birding — even at the movies. For season 8 of the Bring Birds Back, Christian shares the story of a bird out of place in the 2006 film Apocalypto. Listen to the full episode about birds on screen here and in your favorite podcast app.

Common Swifts in Europe nest in eaves and under roof tiles and gables. But modern construction doesn’t have these nooks and crannies, and populations of swifts have been declining. However, there’s a solution called the “swift brick,” a small nesting box that fits right into the wall of a house or

Immature Bald Eagles look so different from mature Bald Eagles that early ornithologists thought they were a different species entirely! Sitting about three feet tall, these majestic birds have wingspans of more than six feet. Stretch your arms as far as you can, and imagine a bird whose reach is

At this time of year, a very young male Bewick's Wren is beginning to learn how to sing. His father sings a crisp well-defined song, separated by pauses, but the young bird's song is fuzzy, unfocused, a little rambling. Each adult male Bewick's Wren has his own set of unique songs. A young wren

Bird voices can vary tremendously. Learning to describe how a bird sounds will make it easier to figure out who’s singing. This episode shares a few common terms to start birding by ear.
