Identificación

The short-billed leaftosser is a stocky bird with a short tail, and has the shortest bill of the Sclerurus leaftossers. It is 15 to 16 cm (5.9 to 6.3 in) long and weighs 19 to 25 g (0.67 to 0.88 oz). The sexes are alike. The nominate subspecies S. r. rufigularis has a dark brown face, sometimes with paler lores and supercilium. Its crown is dark brown with a reddish cast. Its back is dark reddish brown, its rump chestnut-brown, and its uppertail coverts darker chestnut-brown. Its wings are dark reddish brown and its tail is sooty blackish with some faint reddish brown. Its throat and malar are dull orange-rufous that darkens and becomes richer on its upper breast, which has narrow pale streaks. The rest of its breast is darker still and becomes less chestnut to the rich reddish brown belly and flanks. Its iris is dark gray-brown to brown, its maxilla black to gray, its mandible bicolored, and its legs and feet black, brownish, or gray. Juveniles have a duller and browner rump but are otherwise like adults.<p>Subspecies S. r. fulvigularis is more olive-brown than reddish brown. It has a paler throat throat than the nominate and a darker upper breast with wider rufous streaks. S. r. brunnescens is similar to fulvigularis but darker and even less reddish. S. r. furfurosus is overall paler than the nominate.
