In summer, across much of North America, a sudden flash of orange and black in the treetops usually means one thing: orioles. Baltimore Orioles (like this one) in the East, Bullock’s Orioles in the West, and Hooded Orioles in the Southwest and California. These vividly colored birds return…

Generations of birders have puzzled over how to tell Downy Woodpeckers from Hairy Woodpeckers. The two species’ patterns of black and white feathers are so alike that it was long thought they were the closest of relatives. The two live in similar woods, nest in similar trees, and eat many…

The real James Bond was born in Philadelphia in 1900 and worked as a banker after college. But his first love was the natural world. Eventually, he kissed the banking world goodbye and dedicated the rest of his life to exploring and documenting birds and nature.

The Field Sparrow was the first bird song Aldo Leopold awoke to on his farm in the 1940s. In his Sand County Almanac, a classic of conservation and nature writing, Leopold brought to life scenes of nature, a month at a time. Field Sparrows aren't as common today as they were in Aldo…

More than 20 years ago, Professor Ed Rubel of the University of Washington discovered that chickens could repair their own damaged hearing. The birds regrow tiny structures in the inner ear, known as auditory hair cells. Most vertebrates can regenerate these cells - but mammals cannot…

In June 1853, Thoreau wrote of an enchanting encounter with the Wood Thrush: "This is the only bird whose note affects me like music. It lifts and exhilarates me. It is inspiring. It changes all hours to an eternal morning." Wood Thrushes thrive in large expanses of forest. And their…

Each year, the plaintive song of the Eastern Wood-Pewee carries through the forests of eastern North America. For the past 25 years, the number of Wood-Pewees has fallen. But providing economic incentives for private landowners to save forests can help. So can enacting policies that…

The song of this male Black-headed Grosbeak has been described as that of a drunken or scat-singing robin. Compare the songs of both birds, and draw your own conclusion! Singing Black-headed Grosbeaks can be heard from May well into summer, especially in streamside woods. This page is…

The oriole’s name comes from the Latin oriolus, (or-ee-OH-lus) meaning “the golden one.” Despite their similar names, the Eurasian Golden Oriole and the Baltimore Oriole aren’t related at all. Each belongs to a family unique to its side of the Atlantic. As Europeans arrived in North…

In Alaska’s Aleutian Islands, thousands of Whiskered Auklets — miniature relatives of puffins and murres — nest in deep rock crevices. The birds owe their name to the white plumes that sprout from their heads each summer. These fancy “whiskers” likely play a role in courtship. But they're…
