You may not have seen a Northern Cardinal in the wild, but you've probably seen one on holiday cards or the cover of a bird book. During spring breeding season, biologist Eric Lind and his team capture and band birds at Constitution Marsh on the east side of the Hudson River. For eight
Is there any doubt about the identity of America's best known red bird? Surely it's the cardinal or, as you'll find it in a bird book, the Northern Cardinal. The beautiful bird seen on so many bird feeders takes its name from the cardinals found in the Vatican, whose hats and robes are red
Male Northern Cardinals, Scarlet Tanagers, and House Finches all have striking red plumage that’s thought to play a role in attracting mates. Males with the brightest red feathering tend to have the best luck with the females. Scientists think that a male’s redness signals to females that
Because she’s blind, Emily K. Michael experiences birds through their songs and calls. As a birder and poet, she describes hearing three Northern Cardinals singing to each other, as she walked her dog. April is Poetry Month in the US, and we asked Emily to share her poem, Trading Threes
Among most North American songbirds, it’s males alone who sing. But during the nesting season, we also hear female cardinals. Just when she sings and whether or not she matches his song may determine when the male brings food to the nest. Support comes from Sasquatch Books, announcing
In Texas, Pennsylvania, and elsewhere, people have reported seeing Northern Cardinals that are red on one side and brown on the other, indicating that a bird is half male and half female. This anomaly occurs in other species of birds, as well, not just cardinals. Insects, too! Scientists
The annual Great Backyard Bird Count, February 12-15, 2021, is sponsored by the Cornell Lab of Ornithology. Birdwatchers across the country count birds and then report the numbers on-line. Although it may seem that crows are everywhere, the Northern Cardinal is reported on the most lists
Holiday cards often feature gorgeous red cardinals against a snowy landscape. So it’s easy to assume the birds have always been a colorful presence in bleak Northern winters. But cardinals used to be Southern birds. By the second half of the 20th century, though, they were nesting as far
When he was just 22 years old, a young man named Samuel Clemens (who would go on to become the writer Mark Twain) signed on to train as a pilot on a Mississippi riverboat. He quickly realized that, if he volunteered for the early morning shift he could experience one of the most incredible
The male American Robin - fiercely territorial - belts out its distinctive cheery song to defend its breeding territory from invasion by other robins. Sometimes, the robin sees its own reflection as an interloper and challenges the “invader” over and over, even to the point of exhaustion
All states have an official bird, usually one that's associated with its particular region. Many state birds are quite common, although Hawaii's chosen bird, the Nene, a type of goose, is endangered. The bird chosen by the most states — seven — is the Northern Cardinal, followed by the
Birds like finches, chickadees and this Northern Cardinal love sunflower seeds, but each species uses a different strategy to extract the meat. When a finch plucks a sunflower seed from the feeder, it uses its tongue to maneuver the seed lengthwise into a groove on its beak. As it closes
At the crack of the bat, a Blue Jay flies toward first and glides around the base. Deep in left field, an Oriole pounces on the ball. He wings the ball toward second, where a fellow Oriole snares it on a hop - just as the swift Blue Jay slides toward the base in a cloud of red dust. Ahh
Tucked away in southeast Texas is one of the most remarkable enclaves of nature. Known as The Big Thicket, this region is home to ten different ecosystems, including cypress bayous, arid sandylands, palmetto thickets, pine forests, marshes, and grasslands. The variety of natural landscapes
It’s late August, and BirdNote is imagining the bird life at Garrison Keillor’s mythical Lake Wobegon. The loons are now quiet. And the Purple Martins that nested outside the Chatterbox Café? They’re headed for South America. Even the Orchard Orioles - like the pair seen here (female L
As a young boy, David Sibley often explored the outdoors with his father. He recalls turning over logs to look for mole crickets, identifying plants, and watching for birds. We asked David for ways to encourage children to connect with nature: “My advice to other parents is just to get
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
This Carolina Wren doesn't know the precise instant of the vernal equinox of course. But the wren senses the growing hours of daylight through a surge of hormones, which tell it it's time to sing. Both science and folklore tie Spring to the renewal of nature, as the world awakens from the
BirdNote listener, Betsy MacGregor, talks about finding solace in the company of birds. First a bird of the eastern US, a Northern Cardinal, and then a Hutton's Vireo, a bird of the West. The cardinal creates its pure whistle by producing sound in its left and right bronchial tubes
