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.

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...

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 week...

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 ha...

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 .

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 ...

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...

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.

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 .

There are promising signs that a native Hawaiian bird called the ulūlu is on the way to recovery. Also known as the Millerbird, this small gray songbird nearly disappeared when invasive species including rabbits destroyed most of their habitats on the island of Laysan in the early 1900s. In the 2010s, biologists brought 50 individuals from the Nihoa population and reintroduced them to Laysan. From these humble beginnings, the population grew steadily, now sustaining itself at several hundred ind...

A slim, sleek bird with a spiky crest, Phainopepla comes from the Greek for “shining cloak.” The name refers to the male’s glistening, inky black feathers, which are set off by piercing red eyes. And if the Greek name isn’t helping you picture it, a common nickname might: the goth cardinal. From February to April, they nest in pairs in the arid Sonoran Desert. From May to July, they form nesting colonies in leafy oak and sycamore canyons to escape the summer heat. More info and transcript at Bir...

Although some of the Turkey Vulture's habits may evoke our disgust, these remarkable birds also inspire our awe. With wingspans approaching six feet, Turkey Vultures ride currents of air to make their spring and fall journeys, and to cover the miles of their home range in summer. Gliding on updrafts, or pushed along by weather fronts, Turkey Vultures rarely need to flap their wings more than ten times in a row. To rise above storms, they ride upward on thermals.

A young crossbill starts life with a wedge-shaped beak. As it grows up and starts to feed itself by removing conifer seeds from their tough packaging, the tips of its bill begin to grow rapidly — and then they cross. By the time the bird is a month and a half old, the tips of its bill become fully crossed. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter.

Horned Larks rival meadowlarks as the most colorful birds of North American grasslands. They live in prairies, fields, and tundra, but agriculture and development now intrude on many of the Horned Lark's traditional nesting areas. The farmland Conservation Reserve Program encourages agricultural landowners to plant resource-conserving vegetation. This practice protects topsoil and provides habitat for birds like the Horned Lark, as well as other wildlife. More info and transcript at BirdNote.org...

In the arid Arizona desert, where cacti thrive but trees are scarce, the Gila Woodpecker and Gilded Flicker carve out nest cavities in living saguaros. Tall, old saguaros may be pocked with twenty or more nest holes, bearing witness to decades of woodpecker families. The woodpeckers excavate a new nest every year, leaving the old, now-empty cavities behind. But they don't stay empty for long. Elf Owls, Ferruginous Pygmy-Owls, Purple Martins, and Brown-crested Flycatchers all find the slightly us...

A male Buff-breasted Sandpiper courts a female on their breeding grounds far north of the Arctic Circle. He raises his wings, flashing their silvery-white undersides, as he sings his clicking serenade. These birds spend much of the year on grasslands in Argentina, migrating to the Arctic in late spring. In the lower 48, September is a good time to look for this long-distance traveler. During migration, they show a distinct preference for grassy expanses such as pastures and rice fields. Purchasi...

If long migratory flights are amazing, what goes on inside a bird’s body during those flights seems absolutely astonishing. To store fat, birds may eat three times as much and forage over many more hours than normal, as they prepare for long-distance travel. Blackpoll Warblers double their weight in the lead-up to migration. Wilson’s Phalaropes may put on so much fat that they actually have to lose weight to get their fat-loaded bodies into the air. Some birds may need a long running start to ta...

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 en...

New Zealand was once home to a massive parrot that stood three feet tall, about hip-high to most adult humans. It’s estimated that the bird weighed around fifteen pounds, and it probably didn’t fly. But it didn’t need to, because there were no land predators at that time — between 16- and 19-million-years ago! More info and transcript at BirdNote.org . Want more BirdNote?

The flocking movements of homing pigeons are governed by a pecking order. Higher-ranked birds have more influence over how the flock moves. Leading birds change directions first, and followers swiftly copy the leader's movements. And birds at the front of the flock tend to make the navigational decisions. In other words, the pigeons follow the leader. Or leaders . More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter. Sign up for BirdNote+ to get ad-fr...

We often think of birds migrating south in the fall. But many species kick off their big trips surprisingly early in the year. Shorebirds nesting in the Arctic tundra are an extreme example. Birds like the American Golden-Plover have a small window of time to build a nest, find a mate, and lay eggs in the short Arctic growing season. Golden-plovers actually leave their juvenile young behind to begin flying south in mid-summer. The juveniles find their own way to South America later in the year! ...
