Assessment rationale/justification
The species is listed as Least Concern in the UAE in view of its wide distribution, presumed large population and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations outside the UAE is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012).
