Common Kingfisher

Biomimicry - Japanese Trains Mimic Kingfisher

In the 1990s, train engineers in Japan built trains able to travel nearly 170 miles per hour. The problem was that when the trains exited a tunnel, the air in front of their bullet-shaped noses expanded rapidly, creating a loud “tunnel boom.” The chief engineer, a birder, looked to the…

Strange Sounds

What an amazing array of sounds birds have to offer! The call of a male Yellow Rail sounds like someone tapping two small stones together. And Turkey Vultures hissing at one another over a carcass sound like a snarling lion. The duet between the male and female Barred Owls seen here is…
American Coot and its chick

Eavesdropping on Babies

Around this time of year, many baby birds are begging their parents for food. A Hairy Woodpecker chick calls from its nest carved deep within a dying tree. A Great Horned Owl juvenile reminds his parents "Hey! I'm over here! Feed me!" Moving from forest to water, we find this American Coot…

How Birds Produce Sound

Nearly all birds produce sound through an organ unique to birds, the syrinx. In many songbirds, the syrinx is not much bigger than a raindrop. Extremely efficient, it uses nearly all the air that passes through it. By contrast, a human creates sound using only 2% of the air exhaled through…
Song Sparrow

Learning to Listen - Patterns in Songs of the Song Sparrow

Heidi Hoelting, a musician, listens carefully to the songs of birds. In her piano studio at her home in the woods, she wrote down several variations of the different sounds a Song Sparrow makes. In this BirdNote, Nancy Rumbel plays some of those variations on a bamboo whistle. Listen to…
Great Blue Heron pair building nest

A Heron Nest Starts with Just One Stick

During winter and early spring, Great Blue Herons build their nests high in the treetops. The male delivers the supplies to the nest site stick by stick, as the female arranges things. It’s the perfect childhood home for their young, made without blueprints, architects or engineers. But by…
Great Horned Owl fledgling

Great Horned Owls Calling

A fledgling Great Horned Owl calls to be fed. Judging from the young bird's persistence, the parents seem to be responding only with calls, not with food. These entreaties can go on for weeks. Both parents let the fledgling know that it's time for him to feed himself. They've been bringing…

Bird Sound Types and Qualities Part I

Since it’s often hard to see a bird, veteran birders characterize the sounds of birds in order to identify them. So what words do they use? Well, they use “whistle,” for example, to describe the sound of this Olive-sided Flycatcher. And "rattle" for that of the Belted Kingfisher. There's…
Swainson's Thrush

Bird Sound Types and Qualities Part III

When it's just too hard to see the bird you hear, let your ears take over! Listen for the qualities of the sound as well as the pattern. A flute-like and upward-spiraling sound is characteristic of this Swainson's Thrush. Quite a contrast to the plaintively whistled notes of a Black-capped…

Wood Buffalo National Park - Birthplace of Whooping Cranes

In Canada, where Alberta meets The Northwest Territories, lies Wood Buffalo National Park, where endangered Whooping Cranes dance, nest, and raise their young. It's a "place of superlatives,” says park superintendent Rob Kent. “Visitors can see pristine ecosystems, 5,000 bison, 150-pound…
