LC
Barlow's Lark Certhilauda barlowi

Justification
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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to 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 note
Certhilauda erythrochlamys (Sibley and Monroe 1990, 1993) has been split into C. erythrochlamys and C. barlowi following Ryan et al. (1998).

Population justification
The global population size has not been quantified, but the species is described as fairly common in areas with adequate vegetation cover (del Hoyo et al. 2004).

Trend justification
The population is estimated to be in decline following recent local extinctions, perhaps owing to overgrazing (del Hoyo et al. 2004).
