The Hawaii Distinct Population Segment (DPS) of the ʻakēʻakē (band-rumped storm-petrel, Oceanodroma castro) is an endangered seabird that is found throughout the Pacific Ocean basin, and nests in the Hawaiian Islands. Band-rumped storm-petrels are a small seabird measuring approximately 8 inches (20 centimeters) long with a wingspan of 19 in (47 cm), and weighing about 2 ounces (50 grams). The tail is only slightly notched and is almost square in appearance. Plumage is an overall blackish-brown with a white band across the rump, just above the tail. This species typically flies with a relatively shallow wing-beat and glides on slightly bowed wings as a regular part of flight (Slotterback 2002, p. 2). Both sexes are alike in size and appearance. Vocalizations at breeding colonies can be used to further distinguish this species from other Procellariiformes seabirds (albatrosses and petrels) found throughout Hawaii (Allan 1962, p. 279; James and Robertson 1985, pp. 391-392). Band-rumped storm-petrels are long-lived (15 to 20 years). When not at nesting sites, adults spend their time foraging on the open ocean for small fish, squid, and crustaceans
