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. Following the discovery, we analyzed nest site preferences of the Band-rumped Storm-Petrel at this site using a paired design. or so. (Puffinus pacificus) Hawaiian Name: ʻUaʻu kani The Wedge-tailed Shearwater is a very wide-ranging seabird, and one of the most common seabirds in Hawaiʻi. These birds live in somewhat varied habitats depending on the species. LIFE CYCLE: The incubation period for the Hawaiian petrel is 55 days. 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.

Then the petrel flies back to the nest at night, crossing above the surf line, [surf line] ascending to the mountaintop nest burrow. Breeding populations of this species occur on ocean islands throughout the tropical Indian and Pacific Oceans from Madagascar to Mexico. All new lighting must meet specific requirements to minimize disorientation of night-flying petrels. To help prevent potentially deadly groundings, Hawai'i Volcanoes has modified its outdoor lights to be downcast and shielded on the top. Fish and Wildlife Service The Hawaiian petrel returns to the same nest site year after year. 'Ua'u numbers are so low here that the odds of encountering them are rare. At HAVO there are 162 known active nests in three subcolonies (Kapapala, Central, Keauhou) having a total area of 717 hectares (17 72 acres) , of 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. 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. They sometimes have downy feathers, as seen on the head of this bird. Each is dark grey on top and white below.
