Where some noises — like TV, traffic and random conversations — can make it hard to concentrate, birdsong may make it easier. In Alder Hey Children’s Hospital in Liverpool, England, the sweet sounds of birdsong carry along the hallways. In an Amsterdam airport, a lounge plays bird sounds…

Cooper’s Hawks hunts primarily from flight, using speed and stealth to surprise prey — mostly birds like doves. But they’re adaptable and opportunistic in both what and how they’ll hunt. If a Cooper’s Hawk misses catching a sparrow on its first dive, it will sometimes walk into a bush to…

What’s the reddest bird in North America? In the East, the Scarlet Tanager or maybe the Summer Tanager. But neither is seen nearly as often as the Northern Cardinal. In the Southwest, another candidate pops out like a bright red flare on the tip of a branch: the Vermilion Flycatcher. This…

How do birds drink? A robin takes a mouthful of water and then tips its head way back to send the water down its gullet. Pigeons are among the few birds that can suck in water with their heads down. Swallows and swifts skim a beakful of water on the wing. Gulls like this Western Gull can…

The catchy name “Jackdaw” belongs to a European bird that looks like a compact crow drawn in shades of light and dark gray. They are comfortable around people, which helps explain their place in folklore. Some cultures saw the Jackdaw as a predictor of rain, others as a savior of crops. Or…

A flight of White-collared Swifts, huge swifts the size of small falcons, wing their way toward a small waterfall in Southern Mexico. Flying up to 100 miles per hour, they slice right through the waterfall into the cave beyond. White-collared Swifts are found from Mexico to Brazil. By day…

Pterosaurs—the giant, leathery flying creatures of the age of the dinosaurs—were giant reptiles, NOT dinosaurs. The pterosaurs had slim bodies and thin-walled, lightweight bones, ideal for flying. They thrived for 160 million years, passing into history after the same asteroid strike that…

The song of this Field Sparrow was the first bird song Aldo Leopold awoke to on his Wisconsin farm in the 1940s. Sadly, Field Sparrow populations are declining rapidly. You can learn more about "The State of the Birds" from National Audubon, and the plight of the Field Sparrow in…

The Vulturine Guineafowl is a striking bird. It lacks feathers on its head and neck and has a blue breast with silvery plumes. The species has a complex social structure. Distinct groups, similar to high school cliques, mingle but don’t change membership. Such a multilevel society was…

A frantic cacophony of loud, rapid birdcalls tells other birds there’s a predator on the prowl. It’s called “mobbing” as birds clamor and dart — back and forth — at the threat. An ongoing study of mobbing and other bird warning behavior suggests that some birds listen in on the warnings of…
