The Golden-winged Warbler builds its nest in thickets beneath an open sky, which was a rare habitat in the old-growth forests of eastern North America. But the chestnut blight at the turn of the 20th century wiped out billions of trees, an estimated one fourth of the forest in Appalachia…

Dowitchers are a common type of sandpiper seen across North America. Two species, the Short-billed and the Long-billed, stop to feed busily on wetlands during migration from their Arctic breeding grounds to their wintering areas. The origin of the name is unknown. Theories include that it…

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…

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 songs on this show, in order, are: * Bird on a Wire, sung by Judy Collins * Selection from Igor Stravinsky's Firebird Suite * Selection from Lynyrd Skynyrd's Free Bird * Selection from the Trashmen's Surfin' Bird. Thanks to Lori Tingey for her photo of a funky chicken.

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…

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…

Have you ever seen a Peregrine Falcon attack a flock of shorebirds, igniting a breathtaking aerial display? The late falcon researcher Steve Herman called this pattern of evasion "instantaneous synchronicity." The shorebird flock will often form a cone, with the sharpest point shifting…

Unlike mammals, birds have no external ear structures. Their ear openings are hidden beneath feathers on the side of the head, just behind and slightly below the eyes. (It's easy to imagine where this House Finch's ear is, isn't it?) In mammals, the external ear structure helps funnel…
