Population justification: Data from the Atlas of the Breeding Birds of Arabia (Jennings 2010) provides a population estimate of c.10,000 pairs. Therefore, the population size is placed here in the range 10,000-19,999 mature individuals.

Trend justification: There are no new data on population trends; however, the species is suspected to be declining slowly, owing to habitat loss and degradation. Studies in Asir, Saudi Arabia, show that the population has undergone a decline however this could be owing to temporary factors such as a recent drought in the region (M. Jennings in litt. 2016). The evidence for a declining population trend overall in not clear and further studies are required (M. Jennings in litt. 2016).
