Long-Term Trends of ‘ua‘u at Haleakalā National Park

Josh Adams, Jackie Chistolini, and Emma Kelsey (USGS Western Ecological Research Center), in collaboration with Joy Tamayose (Haleakalā National Park) have been analyzing long-term records of ‘ua‘u (Hawaiian Petrel, Pterodroma sandwichensis) at Haleakalā National Park. The objectives of the effort are to determine long-term trends in ‘ua‘u nest occupancy and reproductive output as well as to summarize long-term trends in ‘ua‘u mortality.
