Mangrove Cuckoo found in Florida in winter

Winter Birds of Southern Florida

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 White-throated Swifts, Love Is in the Air

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 Love Ants

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…
Mute Swan resting head on its neck

Swan Song

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 –…
Bohemian Waxwing taking a break from eating Hawthorn berries

Bohemian Waxwings Wander South

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…
Northern Flicker at suet cage

Winter Birds Love Suet

Birds at a suet feeder... What a burst of vitality on a chilly morning! What's the attraction? A cake of suet, suspended from a branch in a small wire feeder. Suet is beef fat, a high-energy food critical for birds' survival in the colder months. Suet is an especially strong magnet for…
Alpine Swifts in flight against a blue sky

Alpine Swifts Fly Nonstop

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 Eagle

The Harpy Eagle Is a Huge, Powerful Hunter

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…
Verdin's winter nest

The Verdin’s Winter Roosts

For small songbirds, surviving a cold winter night can be challenging. Their bodies lose heat faster than those of larger birds. So little birds have found resourceful ways to stay warm — like huddling close together with other birds. But the Verdin, a tiny bird of the Southwest, does…
Kentucky Warbler singing

Kentucky Warbler

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’…
