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…

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…

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…

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…
