Norway rats (Rattus norvegicus) were introduced to the Falkland Islands and are detrimental to native passerines. Rat eradication programs are being used to help protect the avifauna. The present study assesses the effectiveness of eradication programs while using this conservation practice as a natural experiment to explore the ecological resistance, resilience, and homeostasis of bird communities. We conducted bird surveys on 230 islands: 85 in the presence of rats, 108 that were historically free of rats, and 37 from which rats had been eradicated. Bird detection data were used to build occupancy models for each species and estimate species-area relationships. Count data were used to estimate relative abundance and community structure. Islands with invasive rats had reduced species richness of passerines and a different community structure than islands on which rats were historically absent. Although the species richness of native passerines was remarkably similar on eradicated and historically rat-free ... : Detected_Species_Richness_for_each_IslandThis file contains the species detected on each island and information about the island. A species was detected if a '1' appears for that species on that island. The species was not detected if a '0' appears for that species on that island.DetectedS.csvRelative_Abunance_of_each_species_on_each_islandThis file contains the relative abundance values for each species on each island. Values for each species represent the number of individuals counted per kilometers of transect. Metadata associated with each island are also included.Relative_Abunance.csv ...
