In 1974, Eurasian Collared-Doves escaped from captivity in the Bahamas and began to breed in the wild. Soon, they colonized southern Florida. They began expanding in a northwesterly direction, and by the year 2000, they had arrived in the Pacific Northwest. They thrive where backyard trees…

Beginning in 1911, miners in Great Britain carried a canary in a cage with them down into the mines. Why? Carbon monoxide can build to deadly levels, and it has no smell. If the canary weakened or stopped singing, miners knew to get out of the mine — and quickly. Why use a bird instead of…

Gull-watching is pretty tame along the coasts most of the summer. Many gull species retreat north to nest; a few others nest inland. Along the Atlantic, it’s mostly nesting Herring and Laughing Gulls (like this one) that stick around through summer. On the Pacific Coast, it’s Glaucous…

In The Wind Birds: Shorebirds of North America, nature writer and novelist Peter Matthiessen wrote: “The restlessness of shorebirds, their kinship with the distance and swift seasons, the wistful signal of their voices down the long coastlines of the world make them, for me, the most…

Strolling at sunset along the ocean beach at California's Morro Bay or Washington's Leadbetter Point, you hear a male Snowy Plover. At Milford Point in Connecticut, you might hear a Piping Plover. Plovers are threatened in much of their coastal ranges. Conservation efforts are afoot on the…

Nature shows set in Africa often show rhinos and other large mammals with small birds on their backs. They're oxpeckers — like the Yellow-billed Oxpecker pictured here. This relationship was long held up as a textbook example of mutualism. Oxpeckers feed almost exclusively on whatever they…

Even though it’s been known for many years that birds spit out caterpillars they find repellent, little research has been devoted to birds’ sense of taste. It wasn’t until the 1970s that a scientist found taste buds on the inside of a duck’s bill — more than 400 of them. An experiment with…

Every year, the change from winter to spring brings millions of Cliff Swallows from Argentina to North America. Since the early 1800s, swallows had returned, year after year, to the Mission of San Juan Capistrano. But during a restoration project in the 1990s, the venerable mud nests were…

The Northern Flicker is a woodpecker, but one that hardly looks the part. Where most woodpeckers are a reliable mix of black, white, and bits of red, the Northern Flicker is buffy tan overall. The undersides of its wings and tail-feathers flash with coppery-red, giving the bird the…
