BirdNote Daily

Through all of spring and summer, swallows dart and sail overhead, their airborne grace a wonder to behold. But by October, the skies seem empty. Most swallows have flown south, in search of insects. The eight species of swallows that nest in the U.S. — including the Cliff Swallow — migrate south to Central or even South America. Watch for them again next spring!

In Lafayette Park in St. Louis, Missouri, a dozen or so Eurasian Tree Sparrows from Germany were released. But unlike other introduced species such as the similar-looking House Sparrow, they did not spread very far and remained in a limited area in the Midwest. It’s not fully clear why, but it’s possible that they just behave differently. And the aggressive House Sparrow may have helped prevent the tree sparrows from spreading further by competing for the same nesting sites.

In general, the bigger the bird, the higher the number of feathers. Someone counted the feathers on a Tundra Swan and came up with 25,216. At least 80% were on the swan’s neck. Penguins, on the other hand, have lots of small feathers all over their bodies. The largest species is the Emperor Penguin, and one project counted around 80,000 feathers on a single bird. That’s nearly sixty per square inch – keeping the penguin insulated and waterproof in harsh climates. But the most feathered creature ever? It may have been a dinosaur!

Compared to many birds, Great Horned Owls remain with their parents a long time. They hatched in early March, from eggs laid in late January. By April, both parents were hunting through the night to feed their young. But for the last two weeks, the adults have not fed the young. The owlets have learned the skills they need to hunt for themselves. And any night now, the young owls will strike out on their own.

Birds called prions have an especially creative approach to getting their food. They pass seawater through their mouths and filter it to catch tiny animals such as krill and other small crustaceans. It’s similar to how baleen whales feed, leading to the prion’s nickname: the whale-bird. The sides of their bills have comb-like structures. Small food items get trapped in the combs as water flows past. In Greek, the word “prion” means saw, which refers to the bird’s highly specialized mouth.

American Goldfinches are one of our most familiar birds, but they lead lives that are anything but ordinary. These birds will sometimes raise two broods a year, have a secret weapon against cowbirds, and have the ability to distinguish between songs that — to our ears — sound the same. Backyard birds they may be, but American Goldfinches never cease to amaze.

At a glance, swallows and swifts, both graceful fliers, look much alike. But swifts — like this Chimney Swift — have longer, slimmer wings and short bodies, enabling them to glide for long periods. Their glides are punctuated by rapid, stiff bursts of wing-beats. Swallows, on the other hand, flex and flap their wings. Why do swifts have such a peculiar, stiff wing stroke? Picture a bird wing, with two halves jointed in the middle. Swift wings have a short inner “half” and a long outer half. This causes the stiffness.

At the end of summer, the once-bright feathers of a male American Goldfinch look ragged. Growing new flight feathers in a process called molting makes him more vulnerable to predators. Before migrating to wintering grounds, many songbirds stop at a secondary location to undergo the awkward phase of feather replacement. It’s called molt migration. The places birds go to molt could be important targets for conservation efforts.

Once abundant around San Francisco Bay, the Ridgway’s Rail — formerly known as the California Clapper Rail — is now endangered. In the 19th Century, unregulated hunting plundered the species. In the 20th Century, rampant development reduced salt marsh habitat by 85%. But in the 21st Century, the Ridgway’s Rail has allies. Restoration is under way to increase healthy saltmarsh habitat for these endangered birds. Also, efforts to control the number of predatory cats are improving the chances for the Ridgway’s Rail to survive.

Superb Fairy-wrens teach their embryonic chicks a secret code. This "incubation call" contains a special note that will later serve as a password. When the chicks have hatched, this password enables the adult birds to identify their babies in the darkness of their domed nest. A species of Australian cuckoo lays its eggs in the wren’s nest, hoping to pawn off the task of parenting. But wren chicks learn their mother’s song and incorporate the password note into their begging calls.

Let’s talk about nests. Every spring, robins build their cup-shaped nests using grass and mud. Orioles weave a hanging sack. It’s hard work, and yet once the chicks fledge, the structures probably won’t be reused. But bigger birds, such as herons, hawks, and eagles, often reuse a nest for many years. Europe’s migratory White Storks — like those pictured here — get the award for best reuse. One nest site, still used in 1930 and likely seeing many repairs, dated back to 1549. That’s a continuous series of stork pairs nesting in one spot for 381 years!

Keas are large alpine parrots from New Zealand. Intelligent and social, they have olive-green plumage, a red rump, and a long, curved beak. Keas produce a distinct warbling call, a “play call,” that sounds — and functions — much like a human’s contagious laughter. Scientists made recordings of captive Keas making warbling calls, then played them for wild Keas. They began playing harder and even engaged birds that hadn’t been playing. Hearing it seemed to put them in a playful mood, even when they were alone.

In the summer of 2026, conservation photographer Gerrit Vyn visited a remote wilderness called the National Petroleum Reserve in Alaska. He spent much of June at Teshekpuk Lake, just 6 miles south of the Arctic Ocean. The vast wetlands in this region are critical for millions of birds that come from around the world to breed every year. In this episode, Gerrit shares the sights and sounds of three standout shorebirds: Dunlins, Semipalmated Sandpipers, and Pectoral Sandpipers.

By early August, the rich yellow of the feathers of the Wilson's Warbler seems to flash in every forest thicket. Despite predators and weather, many pairs of adults have raised four young, which now flit about on their own. The young males hatched this spring learned their father's songs this summer. Next spring, they, too, will sing those songs. By buying shade-grown coffee, you can help preserve the wintering grounds of this bird and many others.

In September, this Arctic Tern flies from Alaska all the way to Antarctica. Rufous Hummingbirds follow pathways of mountain wildflowers, from as far north as Alaska south to Mexico. Ruby-crowned Kinglets, migrate attitudinally from the mountains to the lowlands. Each of these birds migrates, but on a very different course. All make the most of food and breeding opportunities that change with the seasons.

A tern or gull plunges headfirst into the water, then bounces aloft grasping a small fish in its bill. But before the bird can swallow its catch, a Parasitic Jaeger swoops in. The jaeger nips the bird's wing, and it drops its hard-won fish. The pirate catches the fish in mid-air and gulps it down. The jaeger, which is German for hunter, is built for sprinting speed and predatory feats.

With their excellent sense of smell, pigs are renowned for sniffing out truffles, a fungus that grows underground and is prized for its taste. But it turns out that some bird species can also find their way to a truffle treat. Researchers working in the Patagonia region of Chile had noticed truffles with little beak-sized bite marks, and even watched a bird eat a truffle. They found truffle DNA in the birds’ droppings, suggesting that truffles are a staple of the birds’ diet. Some of the fungi species eaten by the Patagonian birds look like berries that grow locally, whic...

You don’t need fancy binoculars or lavish trips abroad to look for birds. In fact, you don’t even have to leave home — you can enjoy the birds out the window every day. And you don’t actually have to physically go anywhere to find birds. You can use a smartphone or computer to go birding. There are several websites where you can view live feeds of nests. Or you can even have your own bird feeder camera to give you a close-up view of the birds at your feeder.

Many people would tell you that hearing birdsong puts them in a good mood. Recently, scientists have tried to put numbers to this effect that many of us have noticed. One study found that people who spent a few minutes immersed in the sounds of birds had lower levels of paranoia and anxiety than those who only listened to traffic noise.

Some cloudless night in September, when the air is clear, you may see birds flying across the yellow face of the moon! September is peak migration time for millions of songbirds heading south from North America to more tropical latitudes. Nocturnal migrants of the same species, such as orioles, warblers, sparrows, and tanagers, call as they fly, enabling flock-mates to stick together. Many of these flight calls are distinctive, enabling those with an excellent ear to identify them as they pass.

Though half the size of a robin, the Carolina Wren has a powerful singing voice that seems to come from a much bigger bird. Many people remember their song with the phrase, “teakettle-teakettle-teakettle!” When these secretive birds venture into the open, look for their cocked tail, bright white eyebrows, tan breasts, and golden-brown backs. One reason these wrens thrive in cityscapes is their ability to build a nest in creative places: everything from an old boot to a window flower box to an engine block are potential places to raise their brood.

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 any other digging animal. Lyrebirds are best known for their spot-on imitations of other birds’ songs and calls.

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. Fortunately, birds have evolved a structure for protecting their eyes. Beneath the outer eyelids lies an extra eyelid, called the nictitating membrane. It helps keep the eye moist and clean while guarding it from wind, dust, and hazards.

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 when the weather turns bad.

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 dippers dip holds the most promise: Dipping may be a mode of visual communication between these birds in their noisy environment.
