Songbirds delight us with their music, but at times they might sound repetitive. That’s because songbirds have to practice their singing to keep performing at their best. Researchers studying Zebra Finches found that females preferred the songs of males that had been practicing consistently compared

Songbirds delight us with their music, but at times they might sound repetitive. That’s because songbirds have to practice their singing to keep performing at their best. Researchers studying Zebra Finches found that females preferred the songs of males that had been practicing consistently compared to males that had taken a break from singing for …

The Northern Shrike breeds in the tundra and taiga of the north, but migrates south into the lower 48 for the winter. It has a pleasing and rhythmical song, which it sings even in winter. But its song belies a rather bloodthirsty feeding habit. The shrike impales its prey on sharp thorns or barbed

The Northern Shrike breeds in the tundra and taiga of the north, but migrates south into the lower 48 for the winter. It has a pleasing and rhythmical song, which it sings even in winter. But its song belies a rather bloodthirsty feeding habit. The shrike impales its prey on sharp thorns or barbed wire, where it can pull it apart and consume it. Mo…

Holiday cards often feature gorgeous red cardinals against a snowy landscape. So it’s easy to assume the birds have always been a colorful presence in bleak Northern winters. But cardinals used to be Southern birds. By the second half of the 20th century, though, they were nesting as far north as

Holiday cards often feature gorgeous red cardinals against a snowy landscape. So it’s easy to assume the birds have always been a colorful presence in bleak Northern winters. But cardinals used to be Southern birds. By the second half of the 20th century, though, they were nesting as far north as Maine, the northern Midwest, and even southern Canad…

Hummingbirds such as this Buff-tailed Sicklebill specialize in nectar feeding. But other species of birds, less specialized to nectar, also visit flowers for a taste of the sweet stuff. The flowers they visit likely have a more open shape, with nectar more accessible to a non-specialist’s bill. The

The Scaly-breasted Wren lives in Central and South America, and has a lengthy song of whistled notes separated by pauses. By analyzing song recordings, researchers found that Scaly-breasted Wrens can precisely measure out pauses — even as they increase to several seconds. The findings suggest that

The Scaly-breasted Wren lives in Central and South America, and has a lengthy song of whistled notes separated by pauses. By analyzing song recordings, researchers found that Scaly-breasted Wrens can precisely measure out pauses — even as they increase to several seconds. The findings suggest that the wrens have an internal metronome as accurate as…

Boreal Chickadees live in the boreal forest year-round. How do they survive the harsh winter? First, during summer, they cache a great deal of food, both insects and seeds. Then in fall, they put on fresh, heavier plumage. And their feathers are denser than most birds', creating a comfy down parka

In the boreal forest, winter temperatures routinely drop to 30 degrees below zero. Birds that spend the winter in this harsh domain rely on remarkable adaptations to survive. The Spruce Grouse is one such bird. Most Spruce Grouse remain here all year. In the snow-free summer, they forage on the ground, eating fresh greenery, insects, and berries. B…

You may have heard that feeding birds makes them dependent on humans for food, but it’s just not true. Even if you see your local birds ravenously eating at your feeder, those same birds are also finding wild sources of food from elsewhere at other times of the day. That being said, a humble bird

You may have heard that feeding birds makes them dependent on humans for food, but it’s just not true. Even if you see your local birds ravenously eating at your feeder, those same birds are also finding wild sources of food from elsewhere at other times of the day. That being said, a humble bird feeder during a winter cold snap could really help o…

On the north Atlantic coast, a slate-gray sandpiper picks among the barnacles and mussels that encrust a jetty’s massive boulders. At the same moment, a parallel scene unfolds on the north Pacific Coast. A slate-colored sandpiper emerges from the salt spray to forage over a windswept jetty. These

On the north Atlantic coast, a slate-gray sandpiper picks among the barnacles and mussels that encrust a jetty’s massive boulders. At the same moment, a parallel scene unfolds on the north Pacific Coast. A slate-colored sandpiper emerges from the salt spray to forage over a windswept jetty. These look-alikes are the Purple Sandpiper of the Atlantic…

Great Horned Owls have a lot to say! When a pair of Great Horned Owls calls in a duet, the female usually hoots first, and the male replies at a lower pitch. Great Horned Owls may also pierce the darkness with an eerie shriek, which may signal a hungry owlet begging for food or a female defending

Great Horned Owls have a lot to say! When a pair of Great Horned Owls calls in a duet, the female usually hoots first, and the male replies at a lower pitch. Great Horned Owls may also pierce the darkness with an eerie shriek, which may signal a hungry owlet begging for food or a female defending its nest. They can also hiss, pop, meow, coo, and sn…

Screech-owls are opportunistic diners. In the Pacific Northwest, they’ll prey on small birds, crayfish, large ants, or earthworms. In Arizona, pocket mice and pack rats. And in Ohio, biologists who noticed a fishy smell around Eastern Screech-Owl nest boxes found the remains of dozens of shad. It’s
