Aplomado Falcons were once widespread residents of the American Southwest, but by the 1950s, they'd disappeared entirely from the region. Loss of habitat, loss of prey, and pesticides all played a role. But in the 1980s, a group called The Peregrine Fund began breeding captive Aplomado Falcons. Over the next 25 years, 1,500 fledglings were set free in South Texas. At the same time, conservation pacts with private landowners provided more than two million acres of habitat.

Red-tailed Hawks typically have a nesting territory of about a half-mile to a full square mile, depending on how much food there is. Bald Eagles’ nesting territories range from 2½ square miles to as much as 15 square miles, for the same reason. But the Gyrfalcons in Finland and Scandinavia really need their space!

Trumpeter Swans land in a plowed field to forage for remnant potatoes, grain, and other waste crops. This swan is among the largest of all waterfowl; the Tundra Swan is somewhat smaller. These swans migrate in family groups each fall from nesting sites in Canada and Alaska. Learn more about these swans, and view a map to the Skagit Flats of Washington where you can see them. When you go, please be courteous, and if you stop, pull completely off the roadway. Always respect private property.

Palmyra Atoll is a ring-shaped island encircling a lagoon in the South Pacific. The atoll lost many native trees due to U.S. military activity during World War II. Conservationists have worked to restore the ecosystem. Seabirds such as Black Noddies and Red-footed Boobies nest in the island’s rainforest. Their guano enriches the soil, and the soil’s nutrients help support the coral ecosystem that provides fish for the birds. Learn more at BirdNote.org.

When a bird of prey flies over, a flock of crows may dive-bomb the predator and give it a noisy escort out of town. An Eastern Kingbird, like this one, will clamp its feet onto the back of a hawk to send it packing. How do they know which birds to chase off and which to ignore? By genetic wiring, or instinct, but also learning. By watching their parents in the act of mobbing, youngsters gain critical knowledge that may save their own skin. Learn more at BirdNote.org.

Author Nick Belardes was walking at a park near his home in San Luis Obispo, California, when he saw a man who seemed in tune with birds. Belardes asked him what the coolest bird around was, and the man replied Vermilion Flycatcher. Belardes and his wife soon went out looking for the ruby-like bird, finally spotting it through rain and mist. He remembers that sighting as a turning point that drew him deeper into the world of birds. Learn more at BirdNote.org.

When you first glimpse a male Gadwall, you might think you're looking at a female Mallard. But take a closer look, and you'll see plumage as richly and subtly colored as an English gentleman's tweed jacket. For a closer look, click Enlarge under the photo. The Gadwall now nests all across the northern US and into Canada. You can probably see one of these handsome birds on a pond or in a marsh near you. Some may even breed in your neighborhood.

Birds that depend on flies for food have many creative ways of catching their prey. Swallows execute sharp turns and quick changes of speed. Bluebirds watch from a perch, pouncing when the time is right. A Chuck-will’s-widow flies with its scoop-like mouth wide open, engulfing moths and other insects. A Merlin snares dragonflies in its talons. Hummingbirds dart into swarms of midges. Learn more at BirdNote.org.

Not long ago, the only hummingbird that someone living in the eastern United States and Canada could hope to see was the Ruby-throated Hummingbird. But things have changed. Today, more and more hummingbird species — such as this Broad-tailed Hummingbird — have been discovered beyond their “normal” ranges. Why is this colorful explosion happening now? Climate change is one possible factor. So are shifts in migration routes. Or it could just be that more people are on the lookout for these relative newcomers. Learn more at BirdNote.org.

When you think of habitat, think of home. For a jay that lives in the forest, the forest is its habitat – where it finds food, water, shelter, and the company of other jays. Or it might live in your back yard or the bank parking lot down the street. Some birds live in different habitats at different times of year. Many sandpipers summer on the Arctic tundra, but during the rest of the year, they live on coastal tide flats. Learn more at BirdNote.org.
