Inventory of Birds in American Memorial Park, Saipan, Commonwealth of the Northern Mariana Islands, with Special Emphasis on the Status of the Endangered Mariana Moorhen

Reports were scanned in black and white at a resolution of 600 dots per inch and were converted to text using Adobe Paper Capture Plug-in.An inventory of aquatic and forest birds was conducted in the natural areas of American Memorial Park, Saipan, to determine their abundance with emphasis on the status of the endangered Mariana Moorhen (Gallinula chloropus guami). For 12 days in July 2009, 72 stations were surveyed using point counts with variable circular plot methodology. A total of 946 bird observations of 17 species were found within the park. This total included 15 moorhens, four endangered Nightingale Reed-warblers (Acrocephalus luscinia), and ten Mariana Swiftlets (Aerodramus bartschi). The most common species were Bridled White-eyes (Zosterops conspicillatus), Micronesian Honeyeaters (Myzomela rubratra), Golden White-eyes (Cleptornis marchei), and Rufous Fantails (Rhipidura rufifrons saipanensis). This survey confirmed the expansion of the Orangecheeked Waxbill (Estrilda melpoda), an introduced species, into the park as well

Inventory and monitoring of seabirds in National Park of American Samoa

Reports were scanned in black and white at a resolution of 600 dots per inch and were converted to text using Adobe Paper Capture Plug-in.This first island-wide inventory and preliminary monitoring of American Samoa seabird populations has produced several significant results. The beginning of a seabird colony catalog has been established in a digital format. The protocol for surveying seabirds around Tutuila Island by boat is described, and future efforts can be compared to baseline results reported here. A detailed survey of the National Park lands around Tutuila is mapped and photographed and seabird distributions found in the 2000 round-island survey and 2003 partial-island survey are discussed. Our results support anecdotal evidence that the inaccessible north shore of Tutuila supports the majority of that island’s resident seabirds. Greater than 90% of Red-footed Boobies and Great Frigatebird observations during the Tutuila round-island survey were made in NPSA areas. The north shore areas are important for coastal cliff nesters such as Brown, Black Noddies and Blue Noddies, a species of international significance. Bridled Terns are extending their pan tropical range to include Tutuila, including Park areas. White Terns and White-tailed Tropicbirds are more evenly distributed across forests in Tutuila within as well as outside NPSA areas.National Park Service Contract No. 8036 2 900

The Tahiti petrels: night on Mount Lata, Ta'u, National Park of American Samoa

Recordings were originally burned to CD. They were converted into mp3 file format.This CD is an aural window into the ancient past when Polynesia was only populated with seabirds, fruit bats and other things that go bump in the night. Recorded in December 2001 and 2002 using a parabolic dish to amplify calls below the cliff. Surf and wind noise have been filtered out so the birds' calls can be more readily heard. Taped and produced by Mark J. Rauzon with support from the US Fish & Wildlife Service and the University of Hawaii

Invasive mammal eradication on islands results in substantial conservation gains

More than US$21 billion is spent annually on biodiversity conservation. Despite their importance for preventing or slowing extinctions and preserving biodiversity, conservation interventions are rarely assessed systematically for their global impact. Islands house a disproportionately higher amount of biodiversity compared with mainlands, much of which is highly threatened with extinction. Indeed, island species make up nearly two-thirds of recent extinctions. Islands therefore are critical targets of conservation. We used an extensive literature and database review paired with expert interviews to estimate the global benefits of an increasingly used conservation action to stem biodiversity loss: eradication of invasive mammals on islands. We found 236 native terrestrial insular faunal species (596 populations) that benefitted through positive demographic and/or distributional responses from 251 eradications of invasive mammals on 181 islands. Seven native species (eight populations) were negatively impacted by invasive mammal eradication. Four threatened species had their International Union for the Conservation of Nature (IUCN) Red List extinction-risk categories reduced as a direct result of invasive mammal eradication, and no species moved to a higher extinction-risk category. We predict that 107 highly threatened birds, mammals, and reptiles on the IUCN Red List-6% of all these highly threatened species-likely have benefitted from invasive mammal eradications on islands. Because monitoring of eradication outcomes is sporadic and limited, the impacts of global eradications are likely greater than we report here. Our results highlight the importance of invasive mammal eradication on islands for protecting the world's most imperiled fauna
