This is Bird Note.

The song of the canyon run in the American West.

It's a cascade of silvery, whistle notes, what a musician calls a glissando.

The canyon run makes its home in steep, rocky outcrops and vertical stone cliffs.

The birds are found from Mexico all the way through southern British Columbia.

They live among the rocks all year long, nesting in rock piles and beneath overhangs.

Rusty brown feathers give the rent superb camouflage against the rocks.

And its long, slender bill and flattened crown are ideally shaped for probing into deep crevices

for insects and spiders.

With their relatively large feet and strong curved sharp claws, they can clamor up or down

sheer rock faces, or even cling upside down to the ceiling of a cave.

But it's the brilliant song of the canyon run that most people remember best.

A song perfectly suited to echo across the stony realms it calls home.
