Appearance

Distinguishing Characteristics

The Buff-throated Saltator is a large bird with a convex bill. The bird is olive above and grayish below, with a cinnamon buff crissum. It also has a short white supercilium, white chin and upper throat, and buff lower throat with black malar stripe that borders buff throat.

Similar Species

The Buff-throated Saltator is similar to the Black-headed Saltator (Saltator atriceps); the distributions of these two species overlap from Mexico south to Panama. The Black-headed Saltator is larger, with a black crown and a white throat. Another similar species is the Green-winged Saltator (Saltator similis), which overlaps with Buff-throated Saltator in eastern Bolivia and south central Brazil. The Green-winged Saltator, however, has grayer upperparts and an entirely white throat. The distribution of the Buff-throated Saltator also broadly overlaps that of the Grayish Saltator (Saltator coerulescens), but the Grayish Saltator has an entirely white throat, and the upperparts are gray, not olive.

Detailed Description

The following description is based on Ridgway (1901), and refers to subspecies magnoides:

Adult: Forecrown and crown sooty blackish, becoming dusky grayish on nape. Rest of upperparts (back, rump, wing coverts) "plain bright yellowish olive-green." Narrow white supercilium, terminating behind eye. Sides of head plain dull gray. Malar and band across breast black. Chin and upper throat white' lower throat (just above black breast band) ochraceous buff.  Underparts mostly plain light grayish, paler and tinged with buffy on belly; flanks may be tinged with olive. Undertail coverts ochraceous or buffy. Sexes similar.


Juveniles: The juveniles do not acquire the adult plumage until 3-4 months of age. In the juvenile the whitish chin and throat are mottled; supercilium tinged olive; the crown is a dull olive-green; and underparts include a buffy or brownish tinge (Stiles and Skutch 1989).
