After breeding on Arctic cliffs and tundra hillsides in summer, Rough-legged Hawks winter throughout the Northern Hemisphere. Open country is their ideal territory, where the small rodents they depend on are usually so plentiful that the hawks have enough to eat. But the rodents are cyclic, with lower populations in some years, and in those winters…

It’s winter in North America — a good time to head for the subtropical realms of South Florida and listen to the region’s birds, such as the secretive Mangrove Cuckoo pictured here. Rarely seen, it sings sporadically in winter. When it does, you’re sure to take notice. A sweeter voice belongs to the

It’s winter in North America — a good time to head for the subtropical realms of South Florida and listen to the region’s birds, such as the secretive Mangrove Cuckoo pictured here. Rarely seen, it sings sporadically in winter. When it does, you’re sure to take notice. A sweeter voice belongs to the Spot-breasted Oriole. Found in suburban neighborh…

For some birds, love is in the air. When a pair of White-throated Swifts wants to get to know each other, they meet up — on the wing — high above the ground. The birds grasp one another and, clinging together, tumble downward, for over 500 feet. Just before striking the earth, they separate, flying

For some birds, love is in the air. When a pair of White-throated Swifts wants to get to know each other, they meet up — on the wing — high above the ground. The birds grasp one another and, clinging together, tumble downward, for over 500 feet. Just before striking the earth, they separate, flying nonchalantly back up the canyon wall. Visit a West…

That’s not a distant dog barking. It’s a Black Skimmer in flight, at the Chincoteague National Wildlife Refuge in Virginia. This striking, black-and-white bird with a red bill and red feet has a most unusual way of feeding. It flies low along the surface of the water with its beak open. Closely

That’s not a distant dog barking. It’s a Black Skimmer in flight, at the Chincoteague National Wildlife Refuge in Virginia. This striking, black-and-white bird with a red bill and red feet has a most unusual way of feeding. It flies low along the surface of the water with its beak open. Closely related to terns, skimmers nest on sand islands in clo…

Invasive European Starlings are one of the most common birds in North American cities. Recent genetic research into European Starlings shows that populations in North America may have become better adapted to thrive in arid environments and colder temperatures compared to the milder climate of their

Invasive European Starlings are one of the most common birds in North American cities. Recent genetic research into European Starlings shows that populations in North America may have become better adapted to thrive in arid environments and colder temperatures compared to the milder climate of their home range in Europe. Evolution is an ongoing pro…

Woodpeckers, as a group, eat far more ants than most other birds do. Many other vertebrates tend to avoid ants because of their stings or because of the noxious chemicals they contain, like formic acid. But woodpeckers just love them. A Pileated Woodpecker’s diet may include up to 50% ants!

From their cheerful melodies to their vibrant color and skillful acrobatics, there’s a lot to love about Eastern Bluebirds. Look for them along country roads, city parks, and other open woodlands with plenty of grassy patches where they can hunt for snacks. Today’s show is in memory of Bud Oehler

Look for them along country roads, city parks, and other open woodlands with plenty of grassy patches where they can hunt for snacks.

With its rubbery-sounding rattles and clownish red eyebrows, the ptarmigan is quite the stand-out northern bird. As winter approaches, the ptarmigan’s feet grow feathers, and its claws grow longer. All that added surface area means the ptarmigan practically has its own set of snowshoes.

The idea of the "swan song" recurs from Aesop to Ovid to Plato to Tennyson. Ovid described it, "There, she poured out her words of grief, tearfully, in faint tones, in harmony with sadness, just as the swan sings once, in dying, its own funeral song." But it's based on a sweet fallacy – that a swan

The idea of the "swan song" recurs from Aesop to Ovid to Plato to Tennyson. Ovid described it, "There, she poured out her words of grief, tearfully, in faint tones, in harmony with sadness, just as the swan sings once, in dying, its own funeral song." But it's based on a sweet fallacy – that a swan sings only when it nears death. And calling the so…

Thousands of years ago, giant raptors lived on what is now Cuba. Gigantohierax is an extinct genus of eagles whose fossils have been found in local cave deposits and tar seeps.

In winter, when snow blankets the northern states, nearly all of the songbirds that graced the days of summer are gone. But there’s one special winter visitor that fills the absence: the Bohemian Waxwing. In autumn, waxwings wander south from the boreal forest into the northern states and along the Rockies.

Red-headed Woodpeckers have mastered the art of high-contrast fashion. Both males and females have deep-crimson head feathers. Their clean white body feathers are offset by large patches of ink black feathers on their neck, wings, and tail. This is why you’ll hear some folks refer to them as "flying

Their clean white body feathers are offset by large patches of ink black feathers on their neck, wings, and tail. This is why you’ll hear some folks refer to them as "flying checkerboards."

When smaller birds join forces to ward off larger birds, it's called mobbing. This behavior — like calling your family for help — is used by many bird species. The best time to observe mobbing is spring and early summer, when breeding birds are trying to protect their nests and young. Birds

How long can a bird fly without touching the earth? To find out, Swiss scientists attached sensors to Alpine Swifts. The sensors showed long periods when the swifts were gliding and not flapping their wings. Were the birds asleep? Scientists don’t know for sure. It could be that Alpine Swifts sleep

The sensors showed long periods when the swifts were gliding and not flapping their wings. Were the birds asleep? Scientists don’t know for sure. It could be that Alpine Swifts sleep during the summer breeding season — and don’t slee…
