Hawaiian Dark-rumped Petrel Birds populations

Summary:

Once common in Hawaii, the Hawaiian dark-rumped petrel (Petrodroma phaeopygia sandwichensis) is now an endangered seabird that nests in the Hawaiian islands and ranges throughout the Pacific. However, predation by Polynesian man, introduced mammalian predators, fledgling mortality due to light-induced groundings in urban areas, and fluctuations in reproductive success, have greatly reduced the numbers of this petrel to several small relict populations. As a result, the purpose of this study was to assess the relative impact varying rates of survival, mortality, and fecundity in a population and use this knowledge to optimize management efforts. This was done via a Leslie matrix model that was used to evaluate the vulnerability of this endangered species population to the factors that have threatened its survival.
