Penan Bulbul

Subtly attractive tanager, fairly large with striking pale eye. Slaty gray back with olive-yellow crown and belly, dark blackish face. Usually seen in small flocks moving quickly through the understory of forests and edges, seldom sitting still for long. Sometimes joins mixed flocks. Conspicuous call is an explosive chipping, often given repeatedly.

Chunky and short-tailed rainforest wattle-eye. Males are black-and-white, with a white collar all the way around the neck and a very broad black breast band. Females are mostly chestnut, with a white belly and mostly gray head. Both sexes have bluish-purple bare skin around the eyes. Found in the understory and middle levels of rainforest and gallery forest, at middle and low elevations. The vocalizations are highly variable but consist of repeated notes, which can be clear toots or frog-like sounds. 

Medium-sized owl with a heart-shaped facial disc and deep dark eyes; in parts of its range the only Tyto owl present, but compare with larger and darker-winged African Grass-Owl where overlap occurs. Varies across a wide range, but always note white-and-black speckling on the upperparts, beautiful gray-and-tawny wings, and large round head. Color of the facial disc and underparts varies from pure white to rusty orange. Hunts in open areas by night, foraging with a slow and buoyant flight. Roosts in old buildings, tree hollows, caves, and nest boxes by day. Gives a bone-chilling, rising shriek, as well as shorter rasping calls.
