Region
Western Mexico
Typical Environment
Occurs along the Pacific slope of western and south‑central Mexico, favoring arid to semi‑arid shrublands, thorn scrub, and open oak scrub. It uses brushy hillsides, ravines, and edges of agricultural plots where native shrubs persist. The species forages mostly on or near the ground, using patches of dense cover for shelter. It tolerates moderately disturbed landscapes provided there is ample low, thorny vegetation and grassy openings.
Altitude Range
1000–2500 m
Climate Zone

This striking sparrow is named for the bold black 'bridle' pattern on its face. It keeps low in dense scrub and can be surprisingly elusive, often detected by its clear, whistled song. The species is a year‑round resident of western Mexico’s uplands and often becomes more vocal after seasonal rains.
Temperament
wary and secretive
Flight Pattern
short rapid wingbeats with low, undulating flights between shrubs
Social Behavior
Usually found singly or in pairs, sometimes in small family groups outside the breeding season. Nests are placed low in shrubs or grasses, with both sexes involved in territorial defense. Pairs maintain territories in dense scrub and keep close to cover when foraging.
Migratory Pattern
Resident
Song Description
A clear, whistled series of notes and trills delivered from low perches within scrub, often repeated at intervals. Calls include sharp chip notes and softer contact calls given while moving through cover.
Plumage
Warm brown upperparts with darker streaking, a grayish face dominated by bold black lines forming a 'bridle', and pale gray to whitish underparts with a buff wash on the flanks. The tail is fairly long and rounded, and wings show rufous‑brown tones. Overall appearance is crisp and contrasty in the head with more subdued, earthy tones on the body.
Diet
Feeds on grass and weed seeds, small grains, and a substantial portion of insects and other arthropods, especially during the breeding season. It gleanes from the ground and low vegetation, occasionally scratching leaf litter to uncover food. Berries and small fruits may be taken opportunistically when available.
Preferred Environment
Forages along brushy slopes, thorn scrub edges, and grassy openings interspersed with dense shrubs. Often keeps close to cover, moving between clumps of vegetation and open patches where seeds and invertebrates are abundant.
