Abstract
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.
