On the shore of a saltwater bay, the tide goes out, revealing a broad expanse of dark, glistening mudflat. Mudflats are rich in nutrients, such as decomposing organic matter and minerals. Far from wastelands, mudflats also support a bounty of life including vast quantities of tiny snails…

Despite its name, the Burrowing Owl doesn’t do much digging. It’s better known for its hair-raising hiss, which may have evolved to mimic the warning of a cornered rattlesnake. The sonic threat of a venomous reptile could be just enough to warn away most unwanted visitors from the owl’s…

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.

One of the things airplane pilots worry about most is birds colliding with their planes, possibly causing an accident. Preventing bird strikes is a serious concern. Many airports resort to killing birds that might pose a threat. But the airport in Edmonton, Alberta, has found a more humane…

The purpose of anting remains something of a mystery, although most experts agree it has to do with transferring the ants’ secretions to the bird’s body. It’s likely that the ants’ formic acid helps the bird control feather-mites and other parasites. An avian spa treatment!

In the black water of a Louisiana bayou, the water ripples where a slender form glides just beneath the surface. It appears to be a snake, but look closer at the long, narrow spike of a beak. It’s a Snakebird, a colloquial name for the Anhinga, swimming with just its head and neck above…

The Northeast population of Roseate Terns is endangered. Each summer, roughly twenty-five hundred Roseate Terns are found on Ram Island, a 2.5-acre island off the coast of Massachusetts. In the 1960s and 70s, gull numbers surged. Gulls drove terns off of Ram Island, until biologists began…
