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

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 bird…

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

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 researc…

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

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 …

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

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 e…

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

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 pecu…

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

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

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.

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

How much do you know about the lives of female birds? And could you identify, say, a male Scarlet Tanager from a female? This episode’s host and co-founder of the Galbatross Project, Purbita Saha, is here to explain why studying female birds is important. Joining her, ornithologist Joanna Wu details how the often overlooked and understudied female …

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 Niho…

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

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 Son…

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

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 Vultur…

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

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. T…

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
