Лінивка-чорнопер червонодзьоба Monasa nigrifrons

Fairly large, dark bird in lowland forest and forest edge. Bold red bill is striking. Similar to White-fronted Nunbird, but has a black face and is typically found in younger forest and forest edge rather than mature forest. Perches on open branches in the middle and upper levels of forest, sometimes remaining still for long periods. Often travels in pairs or groups, which frequently erupt into a cacophony of noisy, parrotlike warbles.
