The Black-billed Magpie is a familiar sight throughout much of the west. The magpie's bulky nest is a rough sphere of sticks nearly three feet across, with entrance ports on the sides. Take a field trip with your local Audubon and see what you can see!

This month, we’re celebrating BirdNote’s 20th anniversary. Twenty years is a long time, but we can’t hold a candle to Wisdom the albatross, the world’s oldest-known wild bird who is at least 74 years old. Here’s to many more years — for BirdNote, and for Wisdom.

Tree Swallows and bluebirds — like this Western Bluebird — are among the earliest northbound migrants to arrive, heralding spring a month before the equinox. These species will nest only in cavities, such as old woodpecker holes or man-made nest boxes. But the supply of specialized nest…

One of the most difficult skills to pick up as a birder is how to identify birds in flight. You have to sort through a series of visual clues all at once, at high speed: silhouette, wing shape, how fast it flaps, and patterning. An experienced birder will take in all these and other clues…

Most wrens in North America are small, furtive birds that stay deep in the vegetation. But the Cactus Wren is large, bold, and brassy. These wrens are well adapted to the desert and can get all the moisture they need from their food. Cactus Wren nests are a regular sight in their range of…

It’s winter in North America — a good time to head for the subtropical realms of South Florida and listen to the region’s birds, such as the secretive Mangrove Cuckoo pictured here. Rarely seen, it sings sporadically in winter. When it does, you’re sure to take notice. A sweeter voice…

For some birds, love is in the air. When a pair of White-throated Swifts wants to get to know each other, they meet up — on the wing — high above the ground. The birds grasp one another and, clinging together, tumble downward, for over 500 feet. Just before striking the earth, they…

Woodpeckers, as a group, eat far more ants than most other birds do. Many other vertebrates tend to avoid ants because of their stings or because of the noxious chemicals they contain, like formic acid. But woodpeckers just love them. A Pileated Woodpecker’s diet may include up to 50% ants…

The idea of the "swan song" recurs from Aesop to Ovid to Plato to Tennyson. Ovid described it, "There, she poured out her words of grief, tearfully, in faint tones, in harmony with sadness, just as the swan sings once, in dying, its own funeral song." But it's based on a sweet fallacy –…

In winter, when snow blankets the northern states, nearly all of the songbirds that graced the days of summer are gone. But there’s one special winter visitor that fills the absence: the Bohemian Waxwing. In autumn, waxwings wander south from the boreal forest into the northern states and…
