Descriptive names can be a great help when you’re getting to know a new bird. Some species have common names that put their plumage pattern front and center – like the Five-striped Sparrow. If you encounter a bird described as flammulated, lineated, banded, or barred, keep an eye out for their namesake stripes and streaks!BirdNote is grateful to the many contributions of Dr. Gordon Orians, and...

Elegant Black Terns breed in summer on secluded wetlands across the northern states and Canada. Because of major losses of wetlands in their breeding range — especially in Canada's prairie provinces — Black Tern numbers have dropped dramatically since the 1960s. The future of this beautiful bird depends on protecting and restoring high-quality wetlands. Recent research shows that artificial nest...

Skateboarder and birder Dave Mull remembers the first time he heard a Steller’s Jay imitating a Red-tailed Hawk. “These Steller's Jays were pretending to be something they were not, kind of tricking the world,” he says. It got him into the mindset that he could attempt a terrifying new skateboard trick called the “stump jump.”Music in today's episode is by Dave Mull, inspired by the endemic...

Roosters don’t need to set an alarm to tell them when it’s time to crow — their internal circadian clock lets them anticipate sunrise with remarkable accuracy. To us sleepy humans, it may seem like they all start crowing at once. But scientists have found that roosters follow a strict social hierarchy: only the top bird can issue the first cock-a-doodle-doo of the day!More info and transcript at...

Hudsonian Godwits are tough birds to find, and they were once thought extinct due to overhunting. After nesting at sites scattered in the High Arctic, they migrate south on a route that takes them over the ocean from Canada to South America. In spring, they head north through the Great Plains. Populations are estimated to be in the tens of thousands today, but like many arctic nesters, they are a...

In August 2008, Kasatochi Island erupted in the middle of auklet breeding season, burying tens of thousands of chicks in hot ash. At first, the auklets’ future on the island appeared bleak. But in just a few years, the birds had returned in force. Thousands nested within the innumerable chambers left behind by sea-cooled lava.More info and transcript at BirdNote.org.Want more BirdNote?

Beaks suited for opening tough, hard seeds — thick, conical beaks — evolved in more than one lineage of birds. Rose-breasted Grosbeaks are related to cardinals, which also have powerful beaks. Evening Grosbeaks belong to the finch family, which includes goldfinches and crossbills — an entire family of seedeaters. But both these grosbeaks were named before their family connections were fully...

We make it a habit to detail the broad and beautiful spectrum of bird colors, but iridescent feathers are undoubtedly among the most mesmerizing. When sunlight hits the Bufflehead’s dark head feathers at the right angle, their colors transform into shades of the rainbow, from deep violet to green and gold. Common Grackles, caught in natural light, gleam gold, green and blue-purple. Starlings,...

Ross’s Geese and Snow Geese are both white-bodied waterfowl with black wingtips that can be difficult to tell apart. The pair are a great example of what science calls sister species, which occur when a portion of one species takes an evolutionary step away from the rest, resulting in a species split. In this case, genetic studies suggest that the Ross’s Goose branched away from their Snow Goose...

Found in the Sierra Madre, the Arizona Woodpecker has a special connection to the mountain range. Sharing mid-elevation pine and oaks with fellow border straddlers, these small brown birds with white and brown cheeks stand out from other Woodpeckers with their heavily marked white underparts. Uniquely, they forage by flying to the base of a tree and then spiraling up the trunk. And in courtship,...
