How a Bird Came to Look Like a Caterpillar

The Cinereous Mourner is a small, ashy-gray bird that lives in the forest understory of the Amazon Basin. And it’s taking mimicry to the next level: when viewed from above, lying alone in its cup-shaped nest, its chick is a near match to a highly toxic caterpillar — one that snakes and monkeys won’t eat. The chick even waves its head like a caterpillar, increasing the illusion. ¡Escuche este episodio en BirdNote en Español!

Dovekie At Sea

Dovekie are robin-sized seabirds related to auks and puffins. Their compact, black-and-white bodies are perfect for life on the water. In winter, birders and boaters can sometimes spot flocks of Dovekie as far south as coastal New England. In summer, Dovekie high-tail it to the Arctic where they form massive breeding colonies on rocky islands and cliffsides. Dovekie are one of the most abundant birds in the North Atlantic, but their populations have declined drastically since the 1970s. Like many ocean species, Dovekie face lethal threats from oil spills and chemical pollution. By advocating for clean water and green energy, we can protect our global oceans for people and birds — like Dovekie. This episode is brought to you in loving memory of John Hardner, a father and educator who loved nature and public radio. More info and transcript at BirdNote.org. Want more BirdNote?

The Lustrous Purple Gallinule

What’s the most colorful bird in the U.S.? The Scarlet Tanager? Maybe the Painted Bunting? Well, consider one more lustrous candidate: the Purple Gallinule. The Purple Gallinule’s feathers are so iridescent that they might not seem real. Despite its bold style, a Purple Gallinule can be hard to spot. The colors create excellent camouflage among the greens, blues and floral highlights of a marsh.

Chestnut-collared Longspur

The cheerful-voiced Chestnut-collared Longspur shares their northern prairie breeding range with grazing cattle. Although heavy grazing can have adverse effects, breeding densities of longspurs jump by two, three, or even 10 times when ranchers graze their cattle responsibly on native prairies. Two centuries ago, the birds were probably more abundant on prairies used by bison than on untouched stands of tall grass. More info and transcript at BirdNote.org. Want more BirdNote?

Flying Dinosaurs: Leaping and Gliding

For years, scientists debated whether the first flying dinosaurs, the ancestors of modern birds, began by running and making little hops off the ground, or leapt off a tree branch to glide. It’s called the “ground up vs. trees down” debate, for short. But a newer perspective on this mystery suggests that flying dinosaurs tried taking flight from more than one place. Recent findings suggest that the ability to fly could have evolved not just once but three separate times among dinosaurs.
