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…

Along the Gulf of Mexico, you’ll find undeveloped sandy flats and shallow lagoons. This is prime habitat for Wilson’s Plovers to nest and raise their chicks. But life on the beach can be tough for birds. In many parts of its U.S. range on the Gulf and south Atlantic coasts, Wilson’s Plover…

Summer Tanagers snatch bees and wasps in mid-air, as they buzz about. Bug in beak, the bird flies to a perch, slams the insect against a branch until it’s dead, then wipes it against the branch to remove the stinger before eating it. Summer Tanagers will also tear open paper-like wasp…

Many of the waterbirds that winter along the coasts of the Lower 48 spend their summers breeding on tundra ponds and lakes. Loons, grebes, scoters and others call throughout the long summer days. Together, their voices create a symphony that evokes the Arctic north.

Since Killdeer don’t always pick the safest places to lay their eggs, they’ve developed a clever way to protect their young. They use the art of distraction. When it spots a predator close by, the Kildeer parent will pretend it has a broken wing - calling loudly and limping along as it…

The dawn chorus is that time when, just before sunrise, birds begin to sing. One by one, then all together, their voices join to greet the new day. But which bird sings first? The timing of when a bird joins the chorus seems to depend on how well it can see in low light. So the birds with…

It's dawn on a spring day in the Big Cypress Swamp of Florida. Mist rises from quiet water into Spanish moss hanging from the cypress branches. A Limpkin is foraging for apple snails. When it touches a big, round shell, it grabs it quickly and pulls it from the water. Then, moving to solid…

In this episode of BirdNoir, the Private Eye gets a call from his friend Frank, his eyes and ears in the neighborhood. He’s hearing a Red-shouldered Hawk call, but there’s no hawk in sight. Going through the lineup of usual suspects found in backyards, they examine the surprising talent…

Many native cavity-nesters - including this Black-capped Chickadee - will nest in an artificial birdhouse, or nestbox. Look for a nestbox that's plain wood. If the birdhouse comes with a perch, remove it. It just makes it easier for a predator bird to land and go after the eggs or young…

In spring, a male Sooty Grouse calls from a concealed perch high in a tall conifer. Known as “hooting,” it’s a very low-pitched, five or six-note thunking sound. When a female cackles in response, the male flies down and displays to her by strutting and fanning his tail. Females are…
