Green-winged Teal are North America's smallest dabbling duck, at just over a foot long and weighing less than a pound. The male has a cinnamon brown head with a band of green behind the eye. Both males and females have a green bar on the wing that gleams like an emerald when the sun strikes it. During courtship, up to 25 males may court a single female at once.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

The eerie sound of the Great Tinamou can be heard in the lowland jungle throughout much of Central and South America.

With invasive species and climate change, Hawai‘i has experienced so much loss and extinction since Western colonists arrived. But Sam ‘Ohu Gon, the Senior Scientist and Cultural Advisor for the Nature Conservancy of Hawai‘i, is native Hawaiian, and he has done a lot of work connecting Hawaiian culture and tradition to conservation ecology. He hopes that one day, Hawai‘i can be not just a microcosm of ecology, but of conservation as well.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

When Cliff Swallows arrive on the breeding grounds in North America, the dirty work begins. The swallows scoop up mud in their beaks and carefully build a gourd-shaped nest with a tapered opening. They add a lining of dry grass to keep eggs warm. It takes days of work and a thousand mouthfuls of mud to finish a single nest—and it’s just one part of a large colony.More info and transcript at BirdNote.org. Want more BirdNote?

One of the biggest threats to birds is the decline in biodiversity due to habitat loss — and the traditional, manicured lawn isn’t helping. Growing native plants in your yard allows you to protect birds at home, says ecologist Douglas Tallamy, who co-founded an organization called Homegrown National Park® to help people transform their lawns into havens for wildlife.More info and transcript at BirdNote.org.

Northern Cardinals have vocal abilities that surpass even the most accomplished human singers. When cardinals sing, they sweep their voices from the high to low end of their ranges many times in just seconds. The secret is in the clever way cardinals use their two-sided vocal organ, called the syrinx. By dividing their vocal range between the two sides, cardinals can sing complex songs rapidly.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Loons are built for life in the water – so much so that their legs don’t work well on land. During migration, loons sometimes mistake wet pavement for the reflective surface of deep water and try to land there, then become unable to take flight again. If you see a stranded loon on a road or parking lot, calling a wildlife rehabilitator can help start the process of returning that bird to safety and back on their migratory journey.More info and transcript at BirdNote.org.

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.

When writer Lee Ann Roripaugh visited the annual staging grounds of Sandhill Cranes in Nebraska, she was in awe of the birds. During their spring migration, hundreds of thousands of cranes roost on sandbars in the Platte River. The sound and sight of these birds is breathtaking; Lee Ann captures it beautifully in her poem “:: #sandhillcranes #string of beads ::.”More info and transcript at BirdNote.org. Want more BirdNote?

A hummingbird's brilliant throat feathers are called a "gorget," a term applied in past centuries to the metallic swatch protecting the throat of a knight-in-armor. Light waves reflect and refract off the throat feathers, creating color in the manner of sun glinting off a film of oil on water. The gorget of this Rufous Hummingbird is stunning!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.
