The species is a medium-sized member of its genus, with a straight medium-length bill and a slight crest. The sexes have the same plumage but females are smaller than males.

Tyrannine Woodcreeper
Dendrocincla tyrannina
The tyrannine woodcreeper is rather larger and heavier than most others of its genus. It is 23 to 26.5 cm (9.1 to 10 in) long and weighs 40 to 64 g (1.4 to 2.3 oz). The sexes have the same plumage, though males average heavier than females. The nominate subspecies mostly warm brown, with a paler throat, faint buff streaks on its forecrown and behind the eye, and a rufescent cast to the wings and tail. Subspecies D. t. hellmayri is a more olive-brown than the nominate, and has less rufescent wings and tail. Both subspecies have a brown to bluish gray iris and gray to blackish legs and feet. Voice: The tyrannine woodcreeper typically sings from the subcanopy of a ridgetop tree. Its song is "a long stuttered rattle that gradually increases in pitch and volume before trailing off and slowing toward end". Its call is "a fast phrase of 3-6 sharp abrupt notes, e.g., 'di-di-di-di-dik!' ". It also makes "a hollow, whistled 'que-up'."
