By early August, the rich yellow of the feathers of the Wilson's Warbler seems to flash in every forest thicket. Despite predators and weather, many pairs of adults have raised four young, which now flit about on their own. The young males hatched this spring learned their father's songs…

During late summer, these Sooty Shearwaters will join a vast migration, when millions of seabirds fly over the Pacific and Atlantic Oceans. Jaegers that nested on the Arctic tundra are flying south to tropical oceans. Arctic Terns and skuas make an epic journey to Antarctic waters…

Gyrfalcons are circumpolar, nesting in the far north of Asia, North America, and Europe, including Iceland and Greenland. They evolved as a distinct species in the Pleistocene Era, around 100,000 years ago. Their large size and warm feathering gave them an edge for nesting high in the…

For us, an eagle in flight is an image of beauty and power. But for the ancient Greeks, an eagle in flight was an omen - a message from the gods. In Homer's epic, The Iliad, the Greeks have vowed to conquer Troy. But midway through the siege, mighty Hector and the Trojans battle them to…

The Audubon’s Oriole can be heard in the dense woodlands of South Texas, including the Lower Rio Grande Valley. Most of its range lies in Mexico, where it’s known as Calandria Capucha Negra, or lark with a black hood. Dense woodland habitats where the orioles breed have become more…

Sapsuckers, a specialized group of woodpeckers (that includes this Red-naped Sapsucker), don’t actually suck sap. After pecking neat rows of small holes in trees to cause the sugary liquid to flow, the birds lick it up with tongues tipped with stiff hairs. So why doesn’t a sapsucker’s beak…

Farmers have used chemicals to fight insect pests for centuries. Chemical use took on a startling face in the 1940s with the creation of DDT, which had horrifying effects on bird populations. But today, the Wild Farm Alliance is out to prove that farmers don’t have to resort to pesticides…

In summer, the grasslands of southern Saskatchewan resound with bird song. This Bobolink is among the birds that combine their voices in a rich, ringing chorus. Through these grasslands flows the Frenchman River, twisting and looping — the epitome of a meandering river. The southern…

True to its name, the Ruddy Turnstone can turn stones -- and lots of other things along the shore -- in search of food. The bird bends its legs to half their length, places its bill beneath the object to be turned, and with a sudden quick jerk of its head flips it over. For larger objects…

The Flammulated Owl is a study in camouflaged grays and browns, with cinnamon-brown shoulder straps and large brown eyes. This astute aerial predator stands a little more than six and a half inches tall, from its sharp-clawed feet to its stubby, ear-like tufts. It winters in southern…
