Rufous-winged Sparrow

The rufous-winged sparrow is about 15 cm (6 in) long and weighs about 12 to 17 g (0.42 to 0.60 oz). The sexes have the same plumage. Adults of the nominate subspecies have two wide rufous streaks with a thin grayish line between them on the crown. They have whitish lores that become a wide grayish supercilium, a indistinct whitish eye-ring, a rufous stripe behind the eye, and grayish ear coverts with a black stripe below them. Their nape has a grayish collar that the rufous streaks intrude into. Their upperparts are brownish gray with rufous-edged dark brown streaks on the back and scapulars. Voice: Only male rufous-winged sparrows sing. They sing year-round but more frequently in the breeding season, and mostly in the morning. The species' primary song is highly variable and generally begins with introductory notes followed by a trill. One description is "an accelerating series of chips and a few chips followed by a rapid trill". The species' calls include "tzeet, tzlip, and pip" notes.
