Justification of Red List Category
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
The global population size has not been quantified, but the species is described as locally common (del Hoyo et al. 2007).
The population is suspected to be stable since the species is tolerant of degraded habitat and occurs across a broad altitudinal range.
This species occurs in Mizoram (Lushai Hills), India and the Chin Hills of Myanmar.
This species is found in the understorey of broadleaved evergreen forest, forest edge, secondary growth, scrub, fern clumps, bamboo thickets, and tangles of grass and scrub on steep slopes near forest, at 1,300-2,800 m.
Given its broad altitudinal range and tolerance of degraded habitats, this species is unlikely to be at imminent risk from habitat loss.
