Justification of Red List category
Although this species has a small range and a relatively small population size, there are no threats acting in its range thought to be causing declines in population size, occurrence/occupancy, or habitat area. It therefore does not meet or approach either 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 criterion (>30% decline over ten years or three generations), or 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 it is assessed as Least Concern.

Population size: 10000-20000 mature individuals

Population trend: stable

Extent of occurrence (breeding/resident): 3,375 km2

Country endemic: yes
