Long-term monitoring indicates that the Galapagos Penguin is undergoing severe fluctuations, primarily as a result of marine perturbations that may be becoming more extreme. These perturbations have caused an overall very rapid population reduction over the last three generations (34 years). In addition, it has a small population, and is restricted to a very small range, with nearly all birds breeding at just one location. These factors qualify it as Endangered.
