The climate of the earth is changing rapidly, and birds are responding accordingly. Of the 305 species found in North America in winter, nearly 60% have shifted their ranges northward by an average of 35 miles. As some places become unsuitable for the birds now living there, new areas will…

There are a dozen species of hanging-parrots — also known as bat parrots — in the tropical forests of southern Asia and Indonesia. Clad in bright greens, blues, and reds, they sleep —and sometimes bathe — upside down. No other birds sleep like this. This bizarre behavior probably protects…

Where have the birds of summer gone? The Swainson's Thrush is wintering in Central or South America, maybe as far south as Bolivia. Warbling Vireos are now spread through much of Central America, while Black-headed Grosbeaks have migrated to Mexico. This Orange-crowned Warbler also makes…

Long-distance migration can be hard on a bird’s body. For example, this Swainson’s Thrush might migrate between northern Canada and South America, twice a year. In the weeks before such a long journey and during key stopovers en route, the thrush eats like crazy to put on fat. But during…

The Northern Goshawk is one of the most fearsome and admired of all birds of prey — and the largest hawk of the northern forest. Since at least medieval times, falconers have regarded the goshawk as a bird of great distinction. Attila the Hun even wore its image on his helmet. The boreal…

The Pileated Woodpecker makes loud, hard whacks, as it leans back and then slams its bill into the side of a living tree. Sounds painful, if not downright disabling! How does the woodpecker's brain withstand it? All woodpeckers have an enlarged brain case, so the brain sits above the level…

Meet the South Polar Skua, a predatory seabird. During summer in Antarctica, South Polar Skuas feed their young on the chicks of other seabirds. And once their breeding season ends, the skuas fly to northern oceans, such as the North Atlantic, to find large flocks of shearwaters, gulls, or…

There’s at least one bird that nearly everyone knows on sight: Big Bird. He’s been a Sesame Street celebrity since 1969, cutting a colorful figure for pre-school fans and their parents across the world. Big Bird is really a big kid with a kind heart, who makes friends everywhere he goes…

BirdNote contributor Alex Chadwick visited the outskirts of Big Bend National Park in Texas to meet with Kelly Bryan, a retired park manager and biologist who spends his days placing tiny bands on hummingbirds to better know their habits. Kelly has banded more than 14,000 birds! Funding…

Carolyn Ohl-Johnson found a home — and a way of life — near Big Bend National Park. BirdNote contributor Alex Chadwick visited Carolyn at the desert oasis she created for birds such as this Rivoli's Hummingbird. But her accomplishment has required tremendous sacrifice. “I haven’t seen my…
