Spark Bird: Walter and Patch

BirdNote Daily ·

2024/09/10

Sculptor and musician Walter Kitundu first became enraptured by birds in 2005 when a Red-tailed Hawk flew four feet above his head. He named the bird Patch, after the white patch on the back of her head, and kept returning to the park to see her. Patch became used to Walter, accepting him as part of the landscape. He documented her transition from juvenile to adult, learning her quirks and mannerisms.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter

Birds as Pollinators

BirdNote Daily ·

2024/09/09

Birds are part of the complex web of Nature, and each fits into this web in its own way. Some even pollinate flowers! While feeding at a flower, this Rainbow Lorikeet gets pollen on its forehead and throat. When it visits another flower of the same species, it transfers the pollen to that flower. The pollen fertilizes the plant's eggs to produce its seeds, and the plant's reproduction is assured.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Ridgway's Rails on San Francisco Bay

BirdNote Daily ·

2024/09/08

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

Truffle-Hunting Birds

BirdNote Daily ·

2024/09/07

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

Are Birds Nests Reused?

BirdNote Daily ·

2024/09/06

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

The Secret Lives of Goldfinches

BirdNote Daily ·

2024/09/05

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.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Migration: Long, Short, and In-Between

BirdNote Daily ·

2024/09/03

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 altitudinally 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.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter

Can Crows Laugh at Me?

BirdNote Daily ·

2024/09/02

The American Crow’s rattle call is uncommon, and researchers aren’t sure what it means. It could be a gathering call, a predator alarm, or a call between mates. But if you hear it, you might think it sounds like cackling laughter. However, no one has identified a crow noise that indicates glee at the expense of another creature. It’s just a coincidence that the rattle sounds like a laugh. However, crows can play pranks on other animals: egging on cats to fight and yanking on dog tails for their own

Does a Robin Hear Its Worm?

BirdNote Daily ·

2024/09/01

How does a robin know a worm is in one exact spot? Does it see the worm or hear it? Smell it? Sense its movements through its feet? To find the answer, researchers buried worms in soil in a tray. They covered the soil with a thin but opaque sheet of cardboard, followed by more soil, so the robin couldn’t see the worms. Still, the robin found them with ease. The scientists concluded the birds are listening for their prey. There’s always more to learn about birds!More info and transcript at

Catching Insects

BirdNote Daily ·

2024/08/31

Birds that depend on flies for food have many creative ways of catching their prey. Swallows execute sharp turns and quick changes of speed. Bluebirds watch from a perch, pouncing when the time is right. A Chuck-will’s-widow flies with its scoop-like mouth wide open, engulfing moths and other insects. A Merlin snares dragonflies in its talons. Hummingbirds dart into swarms of midges.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter. Sign up for

Warning Eggs About a Warming World

BirdNote Daily ·

2024/08/30

For birds, learning starts early. Birds listen to their parents’ songs and calls from inside the egg. Recent findings have shown that calls from Zebra Finch parents can even prepare their chicks for warmer temperatures before they hatch. Researchers noticed that Zebra Finches make a special high-pitched call, called a heat call, when sitting on their eggs on hot days. Once out of the egg, chicks whose parents made heat calls grow more slowly in the heat. As adults, they seek out warmer spots for

Migrations: Molt Migration

BirdNote Daily ·

2024/08/29

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 indignities of molting. It’s called molt migration. The places birds go to molt could be important targets for conservation efforts.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly

Do Woodpeckers Suffer Brain Injuries?

BirdNote Daily ·

2024/08/28

When woodpeckers drum, they slam their beaks against bark many times per second. Scientists have long hypothesized that woodpeckers have a way of protecting their brains from injury. However, more recent work provides a different picture. High-speed cameras showed scientists that woodpeckers aren’t softening the impacts to their skulls. And researchers also have found signs of cellular damage in woodpecker brains. However, woodpeckers could be protecting themselves in other ways, and may even have

Wood Ducks Succeed

BirdNote Daily ·

2024/08/27

Your eye may be drawn to the gorgeous male Wood Duck, but it is the call of the modestly plumaged female you’ll hear. This call tells the male where his mate is, important as the pair stays together through much of the winter and spring. Wood Ducks are among a small number of North American waterfowl that nest in cavities, and many of them nest in boxes we provide for them.More info and transcript at BirdNote.org. Want more BirdNote?

The Broad-tailed Hummingbird’s Dazzling Dives

BirdNote Daily ·

2024/08/26

Broad-tailed Hummingbirds are small but hardy creatures built for life in the mountains. They survive freezing cold nights by slowing their heart rate and metabolism. And they perform a death-defying stunt for potential mates. Male Broad-tailed Hummingbirds begin their performance by flying up 60 feet or more in the air. Then they dive toward the earth, reaching speeds of up to 50 miles per hour! At the last moment, they pull out of their dive and fly horizontally past the female they’re trying to

Swallow or Swift?

BirdNote Daily ·

2024/08/25

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

What’s a Beak Made Of?

BirdNote Daily ·

2024/08/24

Bird beaks, or bills, come in many shapes and sizes. And birds use them for just about everything: to collect food, preen, fight, court (as this pair of Laysan Albatrosses is doing), chop holes in trees, weave nests, and more. In order for a bird to fly, its beak must weigh as little as possible. Beaks are covered with a sheath of a tough material called keratin, which grows continuously because a beak wears down with use.More info and transcript at BirdNote.org. Want more BirdNote?

2024/08/23

Many people take an interest in birds as they get older. But others start very early, like one young BirdNote listener named Ben Bradmon. He has been learning how to identify birds by their calls. His favorite is the Tufted Titmouse. He has also begun deepening his knowledge of birds by sketching them, letting him focus on details of the birds’ appearance and their habitats.More info and transcript at BirdNote.org.

The Brown Thrasher's Never-Ending Songbook

BirdNote Daily ·

2024/08/22

The Northern Mockingbird isn’t the only mimic bird in town. Brown Thrashers also learn songs from nearby birds and add them to their repertoire. The species has been documented singing over 1,100 different songs: a mix of imitations and invented little melodies. While mockingbirds usually repeat a song or phrase three or more times before moving on, Brown Thrashers tend to repeat a phrase only twice.More info and transcript at BirdNote.org.
