Nest success and predation data for Mariana swiftlets (Aerodramus bartschi), Hawai'i, USA, 2006-2010

This study examined the reproductive biology of the Mariana Swiftlet over five annual cycles on the island of O‘ahu in the Hawaiian Islands. This introduced population used a human-made tunnel for roosting and nesting, and was studied as a surrogate to negate interference with the endangered populations in the Mariana Islands. Active nests (N = 478) were observed in every month of the year. Data recorded included: nest visit dates, date nests were identified, number of visits to each nest; nest stage, nest fate, nest failure status, number of rat traps present, number of rats captures, daily rainfall, and nest ages.
