Identification

Field Identification

Total length 16.5–18 mm (1). A large, bulky, flat-headed sparrow with a pointed, all-black bill (2, 1). Adults of both sexes have a black face and a creamy white supercilium. The sides of the crown are chestnut with black streaks, and the median crown stripe is gray, streaked with black. The pale gray underparts become white on the throat and are washed buff on the flanks (1). Juveniles are similar in coloration but have a yellowish bill, a much duller head pattern, less neatly-marked upperparts, and spotted flanks (1).

Generally rather shy when seen (2), but also described as noisy and conspicuous (1).

Similar Species

Superficially similar to Stripe-headed Sparrow (Peucaea ruficauda), but Striped Sparrow (adult and juvenile) is readily separated from that species by its entirely black bill and brown crown with a less obvious median stripe (2, 1).

Distinguished from Rusty Sparrow (Aimophila rufescens), Rufous-crowned Sparrow (Aimophila ruficeps), and Oaxaca Sparrow (Aimophila notosticta) by its completely white supercilium (including the postocular portion), blackish mask (auriculars), and paler underparts (1).
