Justification of Red List category
This species has undergone extreme population size fluctuations at major colonies in Chile, but there are considerable uncertainties in the population size and trend. Observed declines in Peruvian colonies and an overall reduction in the number of breeding colonies indicate that there is probably an ongoing, underlying rapid decline in numbers. The species consequently qualifies as Vulnerable. However, if the Chilean population, which comprises the majority of the global population, is found to be stable, the species will warrant downlisting in the future.
