Surveys were conducted during 1991 and 1992 to determine the abundance and distribution of the native landbirds of Tutuila, American Samoa. Emphasized are the Pacific pigeon (Ducula pacifica), many-colored fruit dove (Ptilinopus perousii), and the purple-capped fruit dove (Ptilinopus porphyraceus). These data were compared with baseline surveys from 1986. Declines in numbers of almost all landbird species are apparent; and agroforest and plantation land was shown to be marginal habitat for all three pigeon and dove species. The many-colored fruit dove population on Tutuila is critically low, numbering less than fifty individuals.
