Summary, etc. Background: Introduced parasites are a particular threat to small populations of hosts living on islands because extinction can occur before hosts have a chance to evolve effective defenses. An experimental approach in which parasite abundance is manipulated in the field can be the most informative means of assessing a parasite’s impact on the host. The parasitic fly Philornis downsi, recently introduced to the Galapagos Islands, feeds on nestling Darwin’s finches and other land birds. Several correlational studies, and one experimental study of mixed species over several years, reported that the flies reduce host fitness. Here we report the results of a larger scale experimental study of a single species at a single site over a single breeding season. Methodology/Principal Findings: We manipulated the abundance of flies in the nests of medium ground finches (Geospiza fortis) and quantified the impact of the parasites on nestling growth and fledging success. We used nylon nest liners to reduce the number of parasites in 24 nests, leaving another 24 nests as controls. A significant reduction in mean parasite abundance led to a significant increase in the number of nests that successfully fledged young. Nestlings in parasitereduced nests also tended to be larger prior to fledging. Conclusions/Significance: Our results confirm that P. downsi has significant negative effects on the fitness of medium ground finches and they may pose a serious threat to other species of Darwin’s finches. These data can help in the design of management plans for controlling P. downsi in Darwin’s finch breeding populations.
