Justification of Red List category
This species has been uplisted to Endangered as key colonies in South Africa and Namibia are estimated to have undergone very rapid population declines over the past three generations. Declines are primarily believed to have been driven by collapsing pelagic fish stocks, but the species is also susceptible to oiling and avian cholera outbreaks. This trend currently shows no sign of reversing, and immediate conservation action is required to prevent further declines.
