Geographic Range [top]
Range Description: Spenocichla roberti occurs in north-east India from eastern Arunachal Pradesh south to Assam, Nagaland and north Manipur, north Myanmar and adjacent China (western Yunnan). Although it appears to be rare throughout, this impression is at least partly exaggerated because of the infrequency with which its range is visited by ornithologists.
Countries occurrence:
Native:
China; India; Myanmar

Population [top]
Population: The population size is preliminarily estimated to fall into the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.
Trend Justification: The species is suspected to be declining at a slow to moderate rate, owing to logging and habitat degradation resulting from shifting cultivation.
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: 2500-9999 ? Continuing decline of mature individuals: Unknown
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
Habitat and Ecology [top]
Habitat and Ecology: It occurs in evergreen forest with large trees and bamboo on the edge of dense jungle, at 300-2,010 m. It occurs in small parties and feeds on insects, particularly woodlice and boring beetles. It breeds in May-June; its nest is a pad of moss.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Unknown
Generation Length (years): 4.4
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): While the high altitudes favoured by this species are relatively free from habitat loss, shifting cultivation and logging are nevertheless reducing forest cover, at least in north-east India and north Myanmar.
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
None are known.
Conservation Actions Proposed
Study its ecological requirements and its tolerance of habitat degradation. Monitor trends in habitat loss. Protect large areas of suitable habitat at key sites, in both strictly protected areas and community-managed multiple use areas.
