Justification of Red List Category
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.
The global population size has not been accurately quantified, but the species is described as common to abundant in much of its range (del Hoyo et al. 2006). Densities of 10-20 singing birds/ha in the Nile Delta, Egypt, suggest more than 100,000 breeding pairs there (Snow and Perrins 1998) and densities seem similarly high through much of its range (Kennerley and Pearson 2010).
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
