Dark Batis Batis crypta

This species has a very large range, and hence does not 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 appears to be stable, and hence the species does not approach the thresholds for Vulnerable 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.

Taxonomic source(s)

Taxonomic note
Batis mixta (Sibley and Monroe 1990, 1993) has been split into B. mixta and B. crypta following Fjeldså et al. (2006). B. reichenowi (Sibley and Monroe 1990, 1993) has been lumped into B. mixta following Dowsett and Forbes-Watson (1993). This latter treatment is under review by the BirdLife Taxonomic Working Group.

Distribution and population
This species occurs in southern and central Tanzania and extreme north-western Malawi, where it is patchily distributed in montane areas.

Population justification
The global population size has not been quantified, but the species is described as often highly abundant (del Hoyo et al. 2006).

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

The species is found in evergreen forests at 540-2,160 m, moving to miombo woodlands and other wooded areas in lower foothills in the non-breeding season. It is also known to persist in degraded forest and small forest patches (Fjeldså et al. 2006).
