The Hawaiian Petrel, or `Ua`u, nests in small numbers on sub-alpine lava flows within Hawai`i Volcanoes National Park and on each of the main Hawaiian Islands. The species has suffered a drastic decline because of numerous threats. Seth Judge, from the University of Hawaii-Hilo Tropical Conservation Biology and Environmental Science program presents his graduate research. Seth collected data on the traits of this rare seabird from colonies on Hawai`i Island, Maui, Lana`i and Kaua`i. Vocalizations, breeding cycles and the size of petrels from each island are unique. Seth presents the seabird paradox, where a highly mobile species display variation in small geographic areas. The species' instinct to return to natal sites to breed contributes to the isolation of petrel colonies. Join Seth for an amazing evening with one of the rarest of native seabirds.
