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. But in the snowy winter, the grouse live up in the trees, eating nothing but conifer needles. Lots and lots of needles. Because conifer needles are both low in protein and tough to digest, Spruce Grouse grow a bigger digestive system. A grouse's gizzard, which grinds food, may enlarge by 75%!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

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 (pictured here) and the Rock Sandpiper of the Pacific. They embrace a seemingly perilous life amid storm-tossed boulders instead of probing sheltered mudflats like so many of their kin.More info and transcript at BirdNote.org. Want more BirdNote?

It's morning on the island of New Guinea, and the lowland forests erupt with the crowing calls of Birds-of-Paradise. Male Raggiana Birds-of-Paradise perform elaborate displays to attract females, sometimes even hanging upside-down with their wings pointing upward. Forty-three species of Birds-of-Paradise are found on or near New Guinea.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.
