The sapsucker is a type of woodpecker that notches rows of small holes in trees, causing sap to well out. The birds eat the sugary liquid flowing from these sapwells. Tree sap is similar in sugar content to the nectar hummingbirds take from flowers. And it is no coincidence that just as…

Of all American presidents, just one might have halted the playing of “Hail to the Chief” so he could listen to an Orchard Oriole singing — Theodore Roosevelt, “the conservation president.” During his presidency, Roosevelt helped establish 51 preserves for birds, five national parks, 18…

A Mourning Dove lies belly down on the soil of a garden bed. It fluffs its feathers, then relaxes its wings, draping them outward to expose fully its back and rump to the morning sun. A great many birds sun themselves, often in postures that give maximum sun exposure to the head, neck, and…

The Scissor-tailed Flycatcher nests in the open country of Texas, Oklahoma, and the south-central region. It's an elegant bird with a slender, deeply forked tail longer than its body. Agile in flight, it can spread and fold its tail, altering the surface area, like an extra pair of wings…

One of the most ethereal of spring sounds is that made by the Wilson's Snipe. Much as if they were playing a reed instrument, the male snipe produces a winnowing sound in flight by metering, with his wings, the flow of air over his tail-feathers. Among the most venerable of practical jokes…

Most birds molt and regrow their flight or wing feathers—one at a time along each wing—to stay in prime condition for flying. But for a Wandering Albatross, with a whopping 10- to 12-foot wingspan, that’s a big job! It takes the large albatrosses a full year to molt, and they have to put…

Rossini’s 1815 opera, The Thieving Magpie, tells of a household maid who nearly goes to the gallows for stealing silver from her employers. At the last instant, it’s revealed that the thief was actually a magpie. The opera was so popular in its day that it’s believed to have helped cement…

Tricolored Blackbirds nest primarily in California, but smaller groups breed from the state of Washington to Mexico’s Baja California. They look a lot like Red-winged Blackbirds, except Tricolored males have dark red epaulets and white bars on their wings instead of scarlet epaulets and…

In higher animals, the brain is like a Lamborghini — amazing engineering, but expensive to run. In a human, the brain uses about 10 times more energy than other organs. A bird's system is exquisitely attuned to this expense. Several species, including Black-capped Chickadees, have adapted…

Few backyard birds are as beloved as the Black-capped Chickadee. The boldly patterned chickadee is perky, trusting – and it seems to introduce itself by calling its name – chick-a-dee. But when a chickadee voices its namesake call – using a host of variations – it’s most likely maintaining…
