Long-term monitoring of the Galapagos Penguin (Spheniscus mendiculus) indicates that the population is fluctuating, primarily as a result of marine perturbations that may be becoming more extreme through climate change. These perturbations have caused an overall very rapid population reduction over the last three generations (31 years). In addition, the species has a small population and is restricted to a very small range, with breeding confined to a few locations. These factors qualify it as Endangered.
