Audubon's Oriole

Audubon's Oriole

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
Western Bluebird with a pillbug

Wild Farm Alliance

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
Male Mallard duck in eclipse plumage

Male Mallards Disappear

By late summer, the male Mallard’s need for fancy feathers to attract the females has passed. These birds have molted, and their bright feathers are replaced with mottled brown ones. Subdued colors help camouflage the male ducks, protecting them from predators. Come fall, the male Mallards
screech-owl

Night Voices of Summer

At the close of a summer day, the songbirds go silent. As if on cue, the birds of the night make their voices known. In an Eastern woodland, the eerie trills and whinnies of an Eastern Screech-Owl are among the first sounds of the night. Meanwhile, as night falls west of the Rockies, a
Crows and gulls at the shore

The Crow and the Gull

Crows and gulls are opportunists - grabbing a bite wherever, whenever, however they can. Listener Nick Woodiwiss of Vancouver Island, British Columbia, wrote to BirdNote about a funny scene between an American Crow and a Glaucous-winged Gull on the beach. It seems that crows and gulls are
Grasslands of Saskatchewan

Grassland Meander

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
Northern Flicker

Woodpeckers as Keystone Species

Woodpeckers - including this Northern Flicker - are master carpenters of the bird world. They're called "keystone" species for their crucial role in creating habitat suited to other woodland wildlife. Abandoned woodpecker nest-holes become nests or roosts for small owls, cavity-nesting
Brown Thrasher

Shifts in Habitat = Shifts in Species

We asked David Sibley, creator and illustrator of The Sibley Guide to Birds, how changes in the environment are affecting birds such as this Brown Thrasher. He says, “A shift of habitat has caused a shift in the species” he's observed in the Northeastern US. For example, Wild Turkeys
Red-tailed Hawk in flight

Soaring with Redtails

A Red-tailed Hawk soars on broad, rounded wings, the epitome of effortless flight. Without flapping, it traces a leisurely, rising circle. The hawk is riding a thermal, a column of warm rising air generated near the earth's surface by heat from the sun. The Red-tail periodically circles to
Indigo Bunting

Indigo Bunting - Bird of the Ecotone

Many birds – like this Indigo Bunting – can be found in ecotones, the borders between two habitats. Indigo Buntings breed in the ecotone between forest and meadow. They are common at Muscatatuck National Wildlife Refuge in Indiana, where grassland and forest are interspersed to produce
