Passerina versicolor
The Varied Bunting, *Passerina versicolor*, is a strikingly sexually dimorphic songbird famed for the iridescent, variable plumage of its male. Males display a deep purplish-blue head and back, contrasting sharply with a bright crimson nape and rump, and a darker, often blackish body, which can appear entirely black in poor light but erupts with color when viewed correctly. Females are a plain, unstreaked warm brown, making them considerably harder to identify in the field. Measuring 11-13 cm...
Found in arid and semi-arid regions, the Varied Bunting prefers thorny scrub, mesquite woodlands, riparian thickets, and dense shrubby arroyos. It typically occurs at low to mid-elevations, from sea level up to 2500 meters in parts of its range.
The diet of the Varied Bunting consists primarily of small insects, including caterpillars, grasshoppers, and beetles, supplemented with a variety of small seeds from grasses and forbs. They forage mainly by gleaning insects from foliage and picking seeds from the ground.

Males are highly territorial during the breeding season, delivering their distinctive, rapid, jumbled song from elevated, often concealed, perches to proclaim ownership and attract m...

Its distribution continues into parts of Central America, including Guatemala. North...
