Why Birds Stand on One Leg

Birds' legs have an adaptation called "rete mirabile" that minimizes heat loss. The arteries that transport warm blood into the legs lie in contact with the veins that return colder blood to the bird's heart. The arteries warm the veins. Because the veins also cool the arteries, the bird’s

Crow in flight

As the Crow Flies

Traveling "as the crow flies," eating "like a bird," and being "free as a bird" are just a few of the sayings we use to describe everyday human actions and feelings. But these often don't take into account the birds' real activities, relative to their size. Support for BirdNote comes from

Birds in the Winter Garden

Put your winter garden to work as a haven for birds. Leaves and brush left to compost provide foraging and roosting places, smother this year’s weeds, and feed next spring’s plant growth. Watch for juncos and towhees in the leaf litter, and wrens in the brush. Maybe even a Song Sparrow

Responsible Birdfeeding

A clean feeder is a life-and-death matter to some birds. To protect the birds at your feeder, clean it at least once a week, more often if necessary. Rake the ground underneath, too. Pine Siskins are especially prone to salmonellosis, a bacterial disease. You can learn more about feeding

Gerrit Vyn on the Lammergeier

Sound recordist and photographer, Gerrit Vyn, spent two years in the Peace Corps in the mountains of Lesotho. He worked with a chief named Ntate Letsie in the village of Selemong. His people believed that the Lammergeiers, or Bearded Vultures, that nested on the cliff near their village

Father Birds

The male hummingbird leaves the female to build the nest and raise the young alone, but other father birds are more involved. A Peregrine Falcon father shares duties almost evenly with the mother. (Stewart, seen here, nested on a Seattle skyscraper for many years.) But the male Emu of
