Specimens (a downy fledgling and a hatch-year juvenile) and nocturnal calling of the Band-rumped Storm-Petrel (Oceanodroma castro) are evidence that this rare seabird breeds on the island of Hawaii. Noctumal calling over land and sightings near the coast indicate that populations nest on the southwest rift and possibly the upper western slope of Mauna Loa.
