Karoo Long-billed Lark Certhilauda subcoronata

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 note
Certhilauda curvirostris (Sibley and Monroe 1990, 1993) has been split into C. curvirostris (including brevirostris), C. subcoronata (including damarensis and benguelensis) and C. semitorquata by the BirdLife Taxonomic Working Group following review of museum material and the arguments presented in Ryan and Bloomer (1999). Ryan and Bloomer (1999), in addition to splitting curvirostris, subcoronata and semitorquata, propose elevating brevirostris and benguelensis to species level, but this treatment, based largely on genetic evidence, is not supported by morphological and vocal evidence from museum specimens and scientific and popular literature; there is evident ambiguity in the placement of subspecies and differences between them are slight.

Population justification
The global population size has not been quantified, but the species is described as common to very common in most of its range (del Hoyo et al. 2004).

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