Bugun Liocichla

The Bugun liocichla is a small laughingthrush (20 cm (7.9 in)) with olive-grey plumage and a black cap. The face is marked with prominent orange-yellow lores, and the wings have yellow, red and white patches. The tail is black with crimson coloured undertail coverts and red tips. The feet are pink and the bill is black at the face fading to pale white. A second duller individual was mist netted, which was probably the female. The voice is described as fluty and distinctive. A study of the evolution of the species within the genus Liocichla based on mitochondrial DNA sequence similarity showed that the species is most closely related to L. omeiensis with the Hengduan Mountains possibly acting as the isolating barrier between the two.

All sightings of the species have been at an altitude of 2,000 m (6,600 ft) on disturbed hillsides covered with shrubs and small trees, with the exception of one sighting on the edge of primary forest. It lives in a territory similar to that of the Emei Shan liocichla. Small flocks were observed during January, whereas pairs were observed in May, with an estimated total of 14 individuals. It is thought that pairs may hold and defend territories. The Bugun liocichla is only currently known from just one location. Populations may be discovered in other areas of Arunachal Pradesh or neighbouring Bhutan. Attempts have been made to identify new locations where the species could occur based on identification of suitable habitats using computational models.
