Borneo Kocaağzı Batrachostomus mixtus

Small stout frogmouth with a face full of wispy whiskers. Males are dark brown overall; females are bright rufous. Restricted to Borneo’s central and southern mountain ranges, where it inhabits foothill and lower montane forest. Similarly-sized Sunda Frogmouth mostly found in lowland forest. Blyth’s Frogmouth is proportionally longer-tailed, with stronger white markings on the wings and underparts. Vocalizations vary and are poorly understood; frequently gives a mournful descending whistle and a fluid, rippling, downslurred trill.
