Rapid Evolution in the Galápagos Islands

The variety of bill sizes and shapes among the sandpipers is astounding! Many sandpipers have sensitive nerve receptors in their bill tips, so they can find unseen prey through touch, odor, and pressure changes. Those sandpipers with long, straight bills — like the Long-billed Dowitcher — are often described as "stitching." As the bird probes for food, its beak moves rapidly up and down, like the needle on a sewing machine. More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Marbled Godwits stand a foot and a half tall, on slender, dark legs. Their exquisitely long bills are pink, tipped in black, and just slightly up-curved. Altogether, a stunning bird. In April, godwits are on their way north. They have wintered along the coasts, including the Texas Gulf Coast, and along the Pacific from California to Washington. While most breed in the prairie provinces of Canada, some nest as far north as Alaska's Aleutian Islands.

The savanna country of northern Australia is one of the most fire-prone natural habitats in the world, and its plants have evolved to thrive with frequent, low-intensity blazes. As flames sweep across the savanna, Black Kites watch for prey like grasshoppers and lizards that flee the fire. Indigenous Australians have long known that Black Kites aren’t just opportunists — the birds actually create some of these fires by carrying burning twigs in their talons and dropping them on a patch of savanna away from the original wildfire. The kites then pick off the escaping prey. Research suggests that setting a new area ablaze allows these "firehawks" to feed in a space where there aren’t so many rival predators.   More info and transcript at BirdNote.org.

The Keel-billed Toucan, also known as the Rainbow-billed Toucan, looks like a bird with a giant banana for a beak. They have a black body, a yellow patch from the face to the breast, and a huge rainbow-colored bill. The big beaks have more than one use: they can be used for fighting with rivals, but they can also help toucans regulate their body temperature in the tropical heat. ¡Escuche este episodio en BirdNote en Español!

The Canyon Wren and Cactus Wren share common ancestry — and they’re close neighbors in the desert southwest. Yet their songs evolved along divergent acoustic lines. The rough trilled phrases of the Cactus Wren song pulse through the dense cactus, while the clear tones of the Canyon Wren echo off the hard stone, carrying a long distance. ¡Escuche este episodio en BirdNote en Español!

The Tui is one of New Zealand’s most remarkable birds, intelligent and with iridescent feathers. Its down-curved beak fits perfectly into native flowers. But the Tui is best known for its voice. Each Tui’s complex song is slightly different, a colorful mix of musical notes and offbeat sounds. It’s one of the few birds that can imitate human speech — and even accents.
