The pectoral sparrow is sexually dimorphic, and, as the name implies, sparrow-sized, at 15 cm (5.9 in) in length and 24 g (0.85 oz) in weight. Its upperparts are pale green, becoming yellow near the bend of the wing. The head is black, with white on its throat and as stripes on its crown. Its underparts are white in males and creamy in females, with males also having a broad black band going across its breast (a pectoral band). The beak is also black, roughly 14–15 mm (0.55–0.59 in) long for both males and females. Tails are 58–60 and 64–67 mm (2.3–2.4 and 2.5–2. Voice: The song of the pectoral sparrow is a high-pitched buzz, consisting of very short tzik notes (initial tzik note may be slightly faster, and lower in pitch.) and usually followed by 2-4 longer, almost identical tzzzzzz notes. The entire song lasts for 2–3 seconds, at a pitch of 8 kilohertz.

Saffron-billed Sparrow

Arremon flavirostris

Small26 gForest

The saffron-billed sparrow's name comes from its "striking orange bill". The adult male's head is mostly black, with a white supercilium from above the eye to the back of the head. The neck is gray and the back, wings, and tail are green. Its underside is white with grayish edges and a narrow black band across the upper chest. The adult female is similar but duller overall. The female's underparts are buffy with brown flanks. Juveniles are similar to the adults but duller. The species' length is from 15 to 16.5 cm (5.9 to 6.5 in). Voice: The song of the saffron-billed sparrow is a series of rapid notes variously described as "tsit, tsee-tsi-tsi, tseép-seép-tseép" and "sidsidlidsidlsidli". Its call is an insect-like "tseet". It vocalizes on or near the ground.
