This seabird is a small gadfly petrel that lives in the waters of the north west Pacific and nests on islands south of Japan and in the Northwestern Hawaiian Islands. Both, like the Hawaiian petrel, nest in the Hawaiian archipelago but they forage in different regions of the ocean, which will provide further information to examine ocean-wide trends. Seabirds - Hawaiian Islands - U.S. They are usually only seen near land during their breeding season (March to October). The top model in predicting Hawaiian Petrel nest site selection was influenced by increasing slopes, an understory dominated by native vegetation, and open canopy. Shearwaters and petrels nest colonially in crevices, burrows, and under vegetation at mid to high elevations. Millions of central Pacific seabirds congregate on the Hawaiian Islands National Wildlife Refuge to breed. After chicks leave the nest burrow, Hawaiian Petrels and many other seabirds typically spend several years foraging on the high seas as they mature to breeding age, then return to breed at the site where they fledged.

Adults are 16 inches long from head to tail and fly on narrow wings that span three feet. Adults are primarily blackish-brown and have a sharply defined narrow white band across rump area. The Hawaiian petrel (Pterodroma sandwichensis) is actually an endemic seabird merely viewed in Hawaii, where it is threatened and threatened through savage felines that interrupt its nesting reasons. The Hawaiian Petrel is a medium to large seabird that breeds in high elevations on the Hawaiian Islands. HABITAT: Nests in burrows or rock crevices in remote, rugged, high-altitude areas of island interiors The Hawaiian Petrel is called 'Ua'u in Hawaiian for its haunting call, “oo ah oo,” heard after sunset near its nesting colonies. Depredated Hawaiian Petrels are found outside of nest entrances, and carcasses are mostly consumed except for wings, feathers, legs and most of the head. The seabirds were believed to nest on Kauai based on observations of juvenile populations along the coast, but nesting sites had never been found. The 'ua'u, or Hawaiian petrel (Pterodroma sandwichensis), is a federally endangered native seabird. They currently breed on other Hawaiian islands including Kauai and Maui, but were both believed to have extirpated from Oahu prior to European contact in 1778; biologists believed that occasional records from the island were birds thrown off-course at night by city lights.

However, most folks aren't aware that we have petrels on Hawai'i Island as well. On Maui, these petrels are known to nest on Haleakala Crater on East Maui; however, it is not known with certainty whether they also nest in the West Maui mountains in the project vicinity. For some species, it is their only breeding site. Wildlife biologists estimate that only 50 to 60 breeding pairs are left here. nest density and reproductive (fledgling) success in known Hawaiian petrel colonies, (2) what are the long-term trends in colony distribution and density monitored in approximate 5-year intervals, and (3) are these affected by predator control?

The last grounding in the park was in 2006. Their head, wings and tail are a sooty color with a slightly paler back and their forehead and underparts are white with a short tail. Hawaiian Petrel chicks imprint on their birth colony the first time they emerge from their burrows and see the night sky, and they will return to breed at the same colony as adults. Some species are solid and uniform in color, while others have mottled plumage, or feathers. Nests in burrows, crevices, or cracks in lava tubes; nest chamber can be from one to nine meters (3 - … Once grounded, it is difficult for 'ua'u to take flight—leaving them extremely vulnerable to cats, dogs and mongooses. ‘Ua‘u (Hawaiian petrel) nest in colonies, form long-term pair bonds, and return to the same nest site year after year. Seabirds Nest in Alpine Burrows The 'ua'u, or Hawaiian petrel, is a federally endangered native seabird. The Hawaiian petrel (Pterodroma sandwichensis) -- Native Hawaiian name ‘ua‘u-- is a pelagic seabird that spends most of its life in the open ocean, but nests on the main Hawaiian islands, including several national parks.Because its numbers plunged to alarmingly low levels in historic times (it was once considered possibly extinct), the Hawaiian petrel has been federally protected since 1967. To feed their young, adult petrels glide low over the dark ocean, snatching squid from the surface. comm.). In 1987, Hawai'i Volcanoes National Park was designated a World Heritage Site due in part to the high number of endemic species, like the Hawaiian petrel, it protects. They currently breed on other Hawaiian islands including Kauai and Maui, but were both believed to have extirpated from Oahu prior to European contact in 1778; biologists believed that occasional records from the island were birds thrown off-course at night by city lights. Taking turns, both parents incubate the egg for 60 days and feed the chick for an additional four months. nest density and reproductive (fledgling) success in known Hawaiian petrel colonies, (2) what are the long-term trends in colony distribution and density monitored in approximate 5-year intervals, and (3) are these affected by predator control?

This species prefers to nest in burrows underground. "People might be aware of the petrels on Maui since there are many more birds up at Haleakalā National Park, in the thousands. While a primary threat on other islands, groundings are not as common on Hawai'i Island, likely due to a much smaller population of 'ua'u combined with minimal urban lighting, particularly in and around the national park. To help prevent potentially deadly groundings, Hawai'i Volcanoes has modified its outdoor lights to be downcast and shielded on the top. It's a precarious time for one of our rarest endemic seabird species, and the national park is keeping a watchful eye on its small, remaining population.

These birds live in somewhat varied habitats depending on the species. To study and conserve the Newell’s Shearwater, Hawaiian Petrel, and Band-rumped Storm-Petrel, the Kauaʻi Endangered Seabird Recovery Project uses a number of different research and survey methodologies every year. Their diet consists of 50–75% squid, and smaller percentages of fish and crustaceans. LIHUE A cat has been terrorizing Hawaiian petrel burrows in the mountains of the Hono NaPali Natural Area Reserve, and its latest kill was a chick involved in a scientific tracking project. In November, young 'ua'u leave their nests for the first time and fly at night to the ocean searching for food. The birds nest in burrows or rock crevices. The female lays one white egg. The data sets included 993 locations for Newell’s Shearwater on Kauai and 2,545 locations for Hawaiian Petrel on Kauai and Maui. Their head, wings and tail are a sooty color with a slightly paler back and their forehead and underparts are white with a short tail.

'Ua'u were found at nesting at all elevations, including sea level. A primary threat to fledglings are bright urban lights that cause them to become disoriented and fall to the ground or collide with structures. It is believed that the species is monogamous and lives in pairs. After chicks leave the nest burrow, Hawaiian Petrels and many other seabirds typically spend several years foraging on the high seas as they mature to breeding age, then return to breed at the site where they fledged.

Bright urban lights can cause these night-flying birds to become disoriented, collide with structures, or fall to the ground. This returning Hawaiian Petrel appears to have done just that. In the past, considerable amounts of the Hawaiian Petrel’s habitat were converted for livestock, however as the majority of colonies are now protected, this represents a much reduced threat. The seabirds were believed to nest on Kauai based on observations of juvenile populations along the coast, but nesting sites had never been found. If you find a grounded seabird in the national park, please contact dispatch at (808) 985-6170. SPECIES INFORMATION: The ‘akē‘akē or band-rumped storm-petrel is a medium sized, highly pelagic storm-petrel (Family: Hydrobatidae), and is the smallest and rarest seabird that breeds in Hawai‘i.

The majority of known nests on Hawai'i Island are within Hawai'i Volcanoes National Park on the lower alpine and subalpine slopes of Mauna Loa. Hawaiian Petrel Breeding: 70% Success Rate. 'Ua'u numbers are so low here that the odds of encountering them are rare. All new lighting must meet specific requirements to minimize disorientation of night-flying petrels. Hawaiian Petrels first breed after an estimated six years This foraging flight may take two days, even a week.
