Five-striped Sparrow

The Five-striped Sparrow (Amphispiza quinquestriata) is a handsome, highly localized songbird native to the rugged terrain of western Mexico and the southwestern corner of the United States. Renowned among birdwatchers for its extremely restricted US range and secretive habits, this species is a member of the New World sparrow family (Passerellidae). It is a medium-sized sparrow with a striking, high-contrast facial pattern, warm brown upperparts, and a long, dark tail that it frequently twitches. For much of the year, it remains hidden within dense, thorny undergrowth, making it a challenging but rewarding find for avid birders.

The Five-striped Sparrow is named for the distinctive pattern of five crisp white stripes that accent its dark slate-gray head:

• Two Eyebrow Stripes (Supercilia): High-contrast white lines running above each eye.
• Two Mustache Stripes (Submoustachial): Bright white lines defining the lower jaw.
• One Throat Stripe: A prominent white patch directly down the center of its dark throat.

Additional Key Marks:

• Breast Spot: A single, sharp black spot sits in the center of its clean white breast.
• Body Plumage: It features a warm, rufous-brown back and wings that contrast with its cool gray face, chest, and flanks. The underparts are mostly white.
• Tail: Long, dark brown to blackish, and square-tipped, often flicked or cocked upward.

Similar Species:

• Black-throated Sparrow (Amphispiza bilineata): Shares a similar gray and white face but lacks the central white throat stripe, instead showcasing a fully solid black throat and chest patch. It is also found in more open, flat desert scrub rather than steep canyons.

The Five-striped Sparrow has highly specific habitat requirements, strictly associating with steep, rocky hillsides and dry canyon walls choked with dense, tall thornscrub. Plant communities dominated by acacia, mimosa, ocotillo, mesquite, and various desert agaves are essential to its survival.

Geographic Range

• Core Range: The species is primarily resident along the Pacific slope of western Mexico, extending from the state of Sonora south to Jalisco.
• US Distribution: It reaches the absolute northern limit of its range in extreme southern Arizona (restricted to Santa Cruz and Pima counties). Classic locations include California Gulch, Sycamore Canyon, and Chino Canyon.
• Migration: While Mexican populations are permanent residents, Arizona populations are partially migratory or facultative altitudinal migrants, moving to lower elevations or slightly south into Mexico during the coldest winter months.

Behavior & Foraging

Outside of the breeding season, the Five-striped Sparrow is incredibly skulking and difficult to spot. It spends most of its time on the ground or deep within impenetrable thorny ticket layers, hopping quietly in search of food. When flushed, it prefers to fly low and directly into the nearest dense brush rather than taking to the open sky. Its diet changes seasonally: during the spring and summer, it feeds heavily on insects—particularly grasshoppers and caterpillars—while seeds of grasses and forbs sustain it through the dry winter months.

Voice

During the summer monsoon season (typically July through September), males lose their secretive nature and sing persistently from high, exposed perches on shrubs. The song is a variable, dry, metallic series of chips and musical phrases: chip-chip-churr-tsee-tsee-tsee-tsip. The common call note is a sharp, metallic, high-pitched tink or spink.

Breeding

Breeding is closely synchronized with the arrival of the summer monsoon rains, which prompt a flush of insect activity and new plant growth. They build a sturdy, deep cup-shaped nest made of dry grass, bark strips, and fine twigs, lined with animal hair. The nest is typically low to the ground, exceptionally well-concealed inside a dense thorn-bearing shrub or brush pile.
