Family

Description

7-7 1/2" (18-19 cm). Light earth-brown above, with heavy, dark streaking; buff below, with lighter streaking. Outer tail feathers and belly white. Elongated crown feathers sometimes raised in small rounded crest.

Voice

Utters a beautiful, trilling song high in the sky that may last for several minutes. Calls trly or prrit. Also mimics other birds.

Habitat

Grasslands and fields.

Range

Native to Eurasia, northern Africa. Introduced to southern Vancouver Island in British Columbia and San Juan Islands of Washington.

Discussion

The dense rain-forest habitat of much of the Northwest prevents the Sky Lark (often called the Eurasian Skylark) from spreading far from Vancouver Island, where a few pairs were introduced early in this century; it has colonized only the grassy slopes of the neighboring San Juan Islands. This bird's most notable feature is its clear, trilling, often canary-like song. Rising in arcs ever higher until almost out of sight, the songster flutters and sings continuously for three or four minutes, then folds his wings and falls like a stone toward the center of his territory.

Nesting

3 or 4 brown-spotted whitish eggs in a grass nest in a ground scrape.
