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…

From their cheerful melodies to their vibrant color and skillful acrobatics, there’s a lot to love about Eastern Bluebirds. Look for them along country roads, city parks, and other open woodlands with plenty of grassy patches where they can hunt for snacks. Today’s show is in memory of Bud…

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…

In this episode of BirdNoir, the Private Eye sees some suspicious activity: a House Sparrow tries to steal a nestbox from Tree Swallows, but then flees the scene in terror. He stakes out the nestbox to see what the Tree Swallows are doing to keep intruders away.

When smaller birds join forces to ward off larger birds, it's called mobbing. This behavior — like calling your family for help — is used by many bird species. The best time to observe mobbing is spring and early summer, when breeding birds are trying to protect their nests and young…

How long can a bird fly without touching the earth? To find out, Swiss scientists attached sensors to Alpine Swifts. The sensors showed long periods when the swifts were gliding and not flapping their wings. Were the birds asleep? Scientists don’t know for sure. It could be that Alpine…

Harpy Eagles spend their lives in tall, remote tropical forests in Central and South America, flying from tree to tree in search of food. The eagles are named for the Harpies of Greek mythology, women with the bodies of birds who, on Zeus’s command, snatched people from the earth. Since it…

Kentucky Warblers nest in forested regions in much of the East, preferring woodlands with a dense understory, often near streams or other wetlands. These birds can use our help. As their forest habitat shrinks, it’s easier for Brown-headed Cowbirds to find and parasitize the warblers’…
