Human expansion has negatively impacted biodiversity. Oceanic islands have some of the most diverse, endemic biodiversity. Endemism leads to vulnerability due to the isolated and discrete nature of oceanic islands. Birds are indicator species that adapt to change very quickly. By analyzing birds, we can investigate how changes in behavior and abundance may occur for different species in the future. Nine passerine bird species were studied with automated acoustic recording devices. Recording devices were places in agricultural, forest, and mixed habitats. Three invasive species preferred agriculture areas and low canopy cover, based on call frequency and detection probability. Native bird detectability was significantly lower than invasive bird detectability. Occupancy was above 0.8 for all species, except for the gray-green fruit dove that was >0.6. Native bird populations are at risk, based on their calling number and detection probability.
This is a submission to PeerJ for review.
