Sundaschnäpperdrossel Cochoa azurea

Slow-moving and highly elusive chunky Javan endemic, found only in montane and foothill forests. Generally scarce and difficult to pick out in the dark forest due to its coloration and inactive behavior. Males are entirely blue, with some paler highlights on the crown and wings. Female has a mostly dark brownish body with blue most evident in the wings, tail, and crown. Combination of size, shape, and behavior serve to distinguish this infrequently-encountered species from other dark blue forest birds, such as Javan Whistling-Thrush and the Javan subspecies of Sunda Robin. Vocalizations include high, thin whistles and harsh chattering.
