Every spring and summer, birders go in search of the superbly colorful birds that come back to the temperate US from tropical regions — including the Painted Bunting. It just doesn’t seem possible that one bird could pack so much visual impact onto a body that’s only slightly larger than a…

In July, the female Rufous Hummingbird has fledged her first two nestlings and is just about to fledge another. The chick is now as big as its mother, making the walls of the walnut-sized nest bulge outwards at maximum capacity. It takes about 40 days to fledge each brood, from egg-laying…

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…

Great Horned Owls have a lot to say! When a pair of Great Horned Owls calls in a duet, the female usually hoots first, and the male replies at a lower pitch. Great Horned Owls may also pierce the darkness with an eerie shriek, which may signal a hungry owlet begging for food or a female…

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…
