Justification of Red List category
This species is listed as Vulnerable because its population breeds at a small number of wetland locations in arid regions that could be strongly influenced by changes in climate. With such a restricted breeding distribution it is therefore susceptible to stochastic effects and human impacts. The population is also thought to be declining as a result of reclamation of coastal wetlands for development, and human disturbance on breeding grounds that has caused increased mortality of eggs and chicks.
10000-19999 mature individuals
