White-bellied blue robin
The white-bellied blue robin (''Myiomela albiventris'') refers to a kind of bird in the family Muscicapidae endemic to the Shola forests of the higher hills of southern India. The Nilgiri blue robin and this species were once considered separate species, later lumped as sub-species of a single species (''major'') and elevated again to full species in 2005 by Pamela C. Rasmussen. The genus placement remains uncertain although ''Brachypteryx'' is thought to be incorrect due to the lack of marked sexual dimorphism. This small bird is found on the forest floor and undergrowth of dense forest patches sheltered in the valleys of montane grassland, a restricted and threatened habitat.
==Description==
This chat-like bird is long-legged and appears chunky with its short tail and wing. Although sharing similar habits and shape, the two species differ in plumage and both may show slight sexual dimorphism. Differences in iris colour between the females have been suggested for ''M. albiventris''.〔
The white-bellied blue robin (''M. albiventris'') has a black face mask with a short whitish brow. The upperside and breast are slaty blue grading to grey on the flanks. The centre of the belly and vent is white. This can appear somewhat like the male of the syntopic white-bellied blue flycatcher (''Cyornis pallipes'') but can be distinguished by behaviour apart from the longer legs and greyer colouration.〔 Although the plumage is identical between males and females, males are slightly longer winged and have longer tarsi.
