Summary:

Once common in Hawaii, with large colonies located on all of the main islands, the Hawaiian Dark-rumped Petrel (Pterodroma phaeopygia sandwichensis), or Uau, is an endangered petrel whose numbers have been reduced to several small relict populations. Over 85 percent of the breeding birds known today nest in and around the Haleakala National Park on the island of Maui, the site of a three-year study that began in 1979. During this study, the breeding biology, behavior, and conservation needs of this poorly known species were done. This was accomplished by using specially designed event recorders and a closed circuit television system with a night vision scope. Variations in the birds' reproductive success, that occurred naturally and as a result of varying levels of predation by introduced mammals, was documented. Through these observations, it was believed that predation was the primary threat to the birds' survival. With this being the case, it was felt that if this could be controlled, that the remaining populations should thrive.
