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…

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…

During spring at Lostwood National Wildlife Refuge in North Dakota, male Sharp-tailed Grouse - like the one pictured here - perform their elaborate mating dances on a matted patch of ground called a lek. They stomp their feet, extend their wings, and zip around the lek. Then, in an instant…

In Canada, where Alberta meets The Northwest Territories, lies Wood Buffalo National Park, where endangered Whooping Cranes dance, nest, and raise their young. It's a "place of superlatives,” says park superintendent Rob Kent. “Visitors can see pristine ecosystems, 5,000 bison, 150-pound…

A raucous call and a bold flash of blue at your feeder means a jay has arrived. East of the Rockies, your visitor is quite likely a Blue Jay (left). Out west, you're probably seeing a Steller's Jay. These daring blue dandies sound the alarm, announcing the approach of a predator. Often the…

Bald Eagles build large stick nests in tall trees. These nests endure rough treatment. Rambunctious chicks pull sticks out and flap madly, holding on with their feet, before they fledge. Wind buffets the nest year round. But eagles reuse their nests year after year. Adult eagles break off…
