Before the high-tech gadgets used to track bird migration today, there was moon-watching: a technique dreamed up in the 1940s by ornithologist George Lowery. Using telescopes pointed at the moon to see the silhouettes of migratory birds, Lowery helped show that birds regularly migrate…

Williamson's Sapsuckers nest in western mountain forests. The radically different plumages of the male and female so confounded 19th-century naturalists that, for nearly a decade, the birds were thought to be of different species. Sapsuckers are unique among woodpeckers in drilling neat…

The Bicknell’s Thrush is known for scarcity… and promiscuity. Unlike most songbirds, the female thrush establishes a territory and then mates with males that happen by. She then lays eggs that have been fertilized by multiple different males. Many of those males will stick around and help…

Ornithologist Bill Evans has helped us better understand the sounds that birds make as they migrate at night. Known as nocturnal flight calls, many species can be identified based on their signature sound. Using special handmade microphones left outside overnight, Evans, his colleagues and…

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…

Longtime baseball announcer Red Barber often described a player in a winning situation as "sitting in the catbird seat." So what is "sitting in the catbird seat"? And what is a catbird? The Gray Catbird is a cousin of the mockingbird, and it does sound a little like a cat. During breeding…

In 1956, the Eisenhower Administration announced plans for the nation’s new interstate highway system. Planners foresaw 41,000 miles of superior highways, with a grassy border on either side and down the middle. The grassy areas created ribbons of wildlife habitat occupied by small mammals…

In the desert Southwest, water can be scarce. Yet some birds, like this Black-throated Sparrow, thrive in a scorching landscape. The birds obtain moisture from foods like nectar and fruit, as well as insects and other prey. They tuck into the shade in the heat of the day, so they won’t…

Long-billed Curlews are the largest shorebirds in North America. In his courtship display, the male Long-billed Curlew flies a series of arcs across the sky, calling as he goes. Outside of the breeding season, they roost and forage in mixed flocks. When the flock is disturbed, the curlews’…
