While many songbirds are accomplished soloists, some of the bird world’s most impressive performances are actually duets. In North America, breeding pairs of Carolina Wrens sing duets to strengthen their bond and defend territory. More info and transcript at BirdNote.org. Want more BirdNote?

Tree Swallows glisten in the June sunlight, as they swoop and glide, their arcs interlacing in the air. When a white feather flutters down among them, one swallow snatches the feather in its bill and flies upward, as another gives chase. After a moment, the lead bird lets loose the feather, which drifts lazily, until the second bird swoops to catch it in midair. Loose feathers are important for...

Yellow-billed Magpies are clever, colorful birds — and they’re only found in central California. Their hefty bodies are boldly patterned in black, white, and iridescent blue. Like their crow and jay cousins, these corvids are adventurous eaters that often forage on the ground in noisy groups. In California’s oak-dominated woods and grasslands, you’ll find them feasting on acorns, insects, grains,...

Golden-cheeked Warblers, Black-throated Green Warblers, Townsend’s Warblers, and Hermit Warblers share similar songs and plumage. Though they all breed in different areas of North America, they can often be found flocking together on wintering grounds in Central America. Genetic studies have confirmed what their family resemblance suggests: these four warblers are closely related and likely...

Tropical rainforests are stunning places. Despite covering a small part of the Earth’s surface, they support half of the world’s biodiversity. The variety of lifeforms stands out visually in stunning color, and in sound through the strange and beautiful calls of birds. Today is World Rainforest Day, which recognizes the importance of safeguarding rainforests for future generations. More info and...

In marshes across the country, birds awaken on a summer morning. Tall dense grasses and reeds often make marsh birds hard to see, but their voices carry easily across the lush, green landscape. You can hear birds like the Redhead, the Sora, the American Bittern, the Ruddy Duck, this Yellow-headed Blackbird, and many more. More info and transcript at BirdNote.org. Want more BirdNote?

Organized by the Cornell Lab of Ornithology and by Birds Canada, volunteers for Project NestWatch observe local nesting birds and track whether they’re successful in raising their young. Because the nest-watching volunteers monitor birds over a huge area, they cover way more ground than a small team of scientists ever could. Data from Project NestWatch helped scientists reveal that cold snaps and...

Waved Albatrosses produce such slow-growing, needy offspring that females lay only a single egg every two years. And both parents need to share the load until youngsters can hunt on their own. Albatrosses tend to pair for life, and reunited pairs go through an elaborate, synchronized ritual of braying, wing spreading, and bill tapping to reaffirm their bonds.

In the spring, Rufous Hummingbirds journey from Mexico to the northwest U.S., some as far north as Alaska! That’s almost 1,000 miles one way for a bird measuring just under four inches beak to tail, making this the longest migration of any bird relative to body length. Not long after arriving, they bulk up on nectar and bugs for the scenic return trip over the Rocky Mountains. More info and...

White-tailed Kites are distinctive birds of prey. They only live in a few states in the U.S., but they’re common in grasslands throughout much of Central and South America where they hunt for rodents and small prey. Though White-tailed Kites are globally abundant, they still face threats from habitat loss across the Americas. We can support these graceful raptors by preserving the grasslands they...
