Justification of Red List category
This species has undergone extreme population size fluctuations, (close to one order of magnitude) at major colonies in Chile. However, an overall reduction in the number of breeding colonies indicates that there is probably an ongoing, underlying rapid decline in numbers. It consequently qualifies as Vulnerable.
