The 22-inch Great Horned Owl has two tufts of feathers that stick up from the top of its head. This owl is difficult to see, but it's often heard during dark winter evenings and pre-dawn mornings. A pair of owls may call back and forth or overlap their hoots. The male's call is slightly
Ravens are seen as tricksters in many traditions. But Common Ravens have a softer side. During courtship, a pair will often sit side by side, sometimes preening each other's feathers. And during that ritual, one or both may make soft warbling sounds. Raven nestlings sometimes make this
Where have the birds of summer gone? The Swainson's Thrush is wintering in Central or South America, maybe as far south as Bolivia. Warbling Vireos are now spread through much of Central America, while Black-headed Grosbeaks have migrated to Mexico. This Orange-crowned Warbler also makes

Swooping and diving through the air on its long slender wings, the Common Nighthawk emerges at dusk to chase down aerial insects. Nighthawks have short bills that open wide, so they can vacuum up their insect prey as they fly along.
Close kin to the Whip-poor-will, the nocturnal Common Poorwill can be heard in summer in the rocky scrublands of the West at the deep end of dusk. And the Common Poorwill's greatest claim to fame? It was the first bird confirmed to hibernate, based on evidence verified in 1946. Since then
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..."
In a tropical woodland in eastern Australia, you glimpse a Southern Cassowary, a huge flightless bird that must rate as the most prehistoric looking of all birds. Cassowaries are capable of making remarkable sounds, including the lowest known bird call in the world, barely audible to the
