Habitat: <\/strong><\/p>\n\n\n\n

Behavior:<\/strong>\u00a0The Stripe-headed Sparrow is not particularly shy, but its habitat of often dense thorny shrubs, cacti, and agaves in dry canyons can make it difficult to see nevertheless; it tends to avoid hillsides and riparian areas. Stripe-headed Sparrows feed as pairs or in small flocks presumably including non-breeding first-cycle birds. Most foraging takes place in open patches on the ground, though they also glean insect prey from the leaves of trees and, less often, low shrubs. <\/p>\n\n\n\n

Most flights are short-range, though some very long flights can cover as much as 100 yards. The flight is direct and strong, without obvious fluttering or tail movement.\u00a0<\/p>\n\n\n\n

Voice:\u00a0\u00a0<\/strong>Stripe-headed Sparrows are fairly noisy, frequently giving soft zsee <\/em>calls and, when alarmed, loud nasal tchumk <\/em>notes, the latter sometimes in a long, slightly accelerating series. <\/p>\n\n\n\n

Males sing two different songs. One, the \u201cpechew\u201d song, comprises a brief, abrupt one- or two-syllable introduction followed by a cheerfully frantic phrase of five or six squeaky doubled notes, chew\u2014che-pechew-pechew-pechew-pechew. <\/em>They also sing a chattering song, sometimes joined by the female, whose contribution to the duet may be less varied than the male\u2019s notes.<\/p>\n\n\n\n
