Nearly all birds produce sound through an organ unique to birds, the syrinx. In many songbirds, the syrinx is not much bigger than a raindrop. Extremely efficient, it uses nearly all the air that passes through it. By contrast, a human creates sound using only 2% of the air exhaled through
If you watch backyard birds, you will likely see some characteristic behaviors. One example is "foraging" styles — the behaviors that a bird uses to find food. Some birds, such as sparrows, are famous for their "double-scratch" behavior. The bird jumps forward and back, quite quickly
One of the best studies of a North American bird ever written was published by a citizen-scientist named Margaret Morse Nice. Margaret Nice banded more than 800 Song Sparrows in a 40-acre tract in Ohio. Most of us have neither the time nor the 40 acres, but there is still much we can do
Few backyard birds in North America are more widespread than the Song Sparrow. But it was the study of this seemingly unremarkable bird that helped shape modern ornithology. In 1928, Margaret Morse Nice began carefully observing Song Sparrows near Columbus, Ohio, where she lived. For eight
By late January, some resident birds, such as the Northern Mockingbird, are beginning their spring singing. When you step outside on a particularly sunny day this winter, a Fox Sparrow like the one pictured here may be warming up for the coming spring. And as far north as British Columbia
To help backyard birds through the winter, do less. Leave the leaves or rake them under plantings. The tasty insects and spiders underneath will be food for the towhee and this Song Sparrow. Don’t deadhead. Pine Siskins and goldfinches love to snack on dead flowerheads. Make an insect
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
When he was just a kid, Gordon Orians kept notebooks about the birds he saw. And then he realized he could make discoveries – he could add to the body of knowledge and contribute to science. That opened a whole new world to him, and he has spent the rest of his life studying birds and the
By this time in September, most migratory birds have departed. Many resident birds remain, but their voices are now quiet. During fall and winter, birds don't need to sing to establish a breeding territory or attract a mate. Many songbirds lose the ability to sing. The part of the brain
Heidi Hoelting, a musician, listens carefully to the songs of birds. In her piano studio at her home in the woods, she wrote down several variations of the different sounds a Song Sparrow makes. In this BirdNote, Nancy Rumbel plays some of those variations on a bamboo whistle. Listen to
Even in winter, some birds — including Black-capped Chickadees, House Finches, and American Robins — greet the sunrise with song. We normally hear the dawn chorus in springtime, when birds sing to define territory and attract mates. But birds don’t breed by warmth alone. Day length is a
Most bird species in North America mate for a single breeding season. Some may team up again the following year, just because both stay in - or return to - the same territory. Fewer than one-fifth of Song Sparrow pairs are reunited. Hawks, eagles, and ravens have wide territories, thus few
Young male Song Sparrows learn about 10 songs from adult tutors - sometimes from their fathers, but not always. And they learn in stages: 1) "subsong," when the birds babble in a quiet and unstructured way; 2) the "plastic" stage, which contains recognizable adult syllables but is still
Some birds have a remarkable knack for staying out of sight. Often we don’t know they’re nearby, until they sing. But with a little practice, we can learn to identify birds without seeing them. Listen to the songs of the Song Sparrow, the Chipping Sparrow, and the White-throated Sparrow —
Uncle Remus told us how Br’er Rabbit fooled Br’er Fox by pleading, “Pleeeeze don’t throw me in that briar patch.” Many birds, like this Song Sparrow, thrive in dense, thorny blackberry thickets. Other birds that make these thorny thickets home include California Quails, wrens, and many
John Burroughs, one of the masters of American nature writing, wrote "The birds do indeed begin with the day. The farmer who is in the field at work while he can yet see stars catches their first matin hymns. In the longest June days the robin strikes up about half past three o'clock..."
