American Samoa wildlife investigations: bird studies
Seamon JO. 1997. American Samoa wildlife investigations: bird studies. Annual report FY1997. Department of Marine and Wildlife Resources. Pago Pago, AS
Annual report about bird surveys on abundance, distribution, and habitat that were conducted on Tutuila, American Samoa during October 1996 to Septermber 1997. Bird studies (Ducula pacifica) of demographic patterns among sites indicate significant differences among some of the sites in average abundance, and sites with greater abundances had higher population growth rates. However, the trajectories among sites with similar abundances were not correlated, suggesting that processes (perhaps temporal patterns of availability of specific resources) unique to each site influence temporal patterns of abundance.
