[BIRD NOTE THEME]

GELLERMAN: Today's Birdnote® takes us to the U.S. West - and profiles a bird that delights many who hike the region’s canyons. Here's Mary McCann.

[WHITE-THROATED SWIFTS CHATTERING IN FLIGHT]

MCCANN: A torrent of shrill notes ricochets off the sheer, stone walls of a Western canyon.

[WHITE-THROATED SWIFTS CHATTERING IN FLIGHT]

MCCANN: A pair of White-throated Swifts careens by at high speed, revealing boldly patterned bodies. They twist and turn, sailing through the air on black, scimitar-shaped wings spanning 15 inches. Dashing headlong across the canyon toward an unyielding wall, the birds disappear at the last second into a slender crevice.

MCCANN: This swift is aptly named – and doubly so. Flying at tremendous speed, the White-throated Swift is indeed swift, among the fastest of all birds. And its lyrical, scientific name suits it perfectly: Aeronautes saxatalis* – sailor of the air who dwells in the rocks.

MCCANN: Swifts leave the air only to nest or roost in a cavity. You’ll never see one perched. They do everything else while airborne. Ornithologist Percy Taverner said of them, “When mating, a pair meet…high in the air, cling together as though embracing for a moment …drop down hundreds of feet, then separate and catch themselves on their wings…”
