These days we're hearing the song of the Olive-sided Flycatcher less often. Clear-cutting and fire suppression in forests, along with acid rain, has reduced its available habitat. Pesticides affect the supply of food. American Bird Conservancy has named it a priority species for…

In 1987, when Project FeederWatch began, Evening Grosbeaks were among the most common birds at birdfeeders during the Northeast winter. Now they're completely absent in many of those same areas. In the West, too, they're showing up in reduced numbers. Why have so many Evening Grosbeaks…

On the Summer Solstice, the longest day of the year, birds across the North American continent greet the dawn — from the Florida Keys and the marshes of Chesapeake Bay, from the Rio Grande Valley of Texas, home of this Audubon's Oriole, and the great plains of North Dakota, to the…

High in the mountains of the West and North, where the long summer days stay cool, the song of the Hermit Thrush stands out. The song has been described as "ethereal," "serene," or "flutelike." Writer Ralph Hoffman writes about the song of the Hermit Thrush: "It is the opening note that…

In his poem “Trying to Fall Asleep in South Dakota,” poet Tom Gannon wrote about meadowlarks. He might have been hearing a Western Meadowlark, which nests across South Dakota in the summer. But if he’d been in the south-central part of the state, it might have been an Eastern Meadowlark…

Because many woodpeckers have pointed tongues, it was once assumed that they “harpoon” their prey. But what they actually do is more complex. Like a safe-cracker in a movie, birds like this Hairy Woodpecker use a killer combination of sensitivity and force. First, as it scales a tree trunk…

Tallgrass prairie, a sea of grass, once stretched from Manitoba to Texas, a landscape of almost unimaginable natural abundance. Heading west, Lewis and Clark came upon savannahs as far as the eye could see, covered with herds of bison, elk, pronghorn, and deer. Only a tiny fraction of the…

Woodlarks are birds of the rolling heathlands and forest glades of southern England, as well as other parts of Europe. Like most kinds of larks, Woodlarks are all but impossible to spot on the ground. Fortunately, they sing from the air, as they fly in graceful, circular patterns, their…

One of Hawaii’s rarest forest birds is this ‘Akiapola’au. Some of the roughly 1,000 'Akis left on earth live and breed in kipukas on the lower slopes of Mauna Loa, Hawaii’s largest active volcano. A kipuka is an island of native forest surrounded not by water but by recent lava flows - a…

Kakapos are large, flightless parrots unique to New Zealand. Hoping to attract females, several males gather in a “lek.” They sing at the same time, and the deep-pitched notes carry a long distance. Females may wander in from as much as a mile away. This booming competition goes on for…
