Varied Bunting

The Varied Bunting is a small, richly but subtly colored songbird of arid borderland scrub, closely related to the more familiar Indigo and Painted Buntings. Adult males show a complex, iridescent mix of deep purple, blue, and reddish tones that shift dramatically with the angle of light, often appearing almost black in shade but glowing with rosy-pink on the nape and a deep blue crown and rump in direct sunlight. Females and immature birds are a plain grayish-brown overall, lacking any obvious field marks, among the plainest of all the buntings.

A bird of thorny desert washes and brushy canyons along the U.S.-Mexico borderlands, the Varied Bunting is less commonly encountered than its relatives and often stays low and hidden within dense, thorny vegetation.

Key Field Marks

• Adult male: appears blackish at a distance, but shows deep purple-blue body, a rosy-red patch on the nape, and a blue crown and rump in good light
• Female/immature: plain grayish-brown overall, unmarked face, no wingbars
• Small, stocky build with a short conical bill

Similar Species

• Indigo Bunting males are a brighter, more uniform blue without the rosy nape patch or purple iridescence.
• Painted Bunting males show a clean blue head, green back, and red underparts, quite different from the more uniformly dark, iridescent Varied Bunting male.
• Female Varied Buntings are extremely plain and best identified by range, habitat, and association with a male.

Habitat

Favors dense, thorny desert scrub, brushy arroyos and washes, and streamside thickets in arid canyons, typically at lower elevations of desert borderlands.

Range

Breeds in the southwestern United States (southern Arizona, New Mexico, and Texas) south through Mexico to Central America.

Migration

Most U.S. breeders migrate south into Mexico for winter, though the species is resident year-round in parts of its more southern range.

Behavior

Varied Buntings tend to stay low and secretive within dense, thorny cover, making them harder to observe than other buntings despite the male's striking coloration in good light.

Voice

The song is a bright, warbling series of notes similar to other Passerina buntings, though often described as softer and more variable; the call is a sharp, thin "chip."

Feeding

Feeds on seeds and insects, foraging low in dense brush and on the ground.

Nesting & Breeding

The female builds a compact cup nest low in dense, thorny shrubs, providing protection from predators. She incubates the eggs alone, and pairs may raise multiple broods during the summer rainy season in parts of the range.
