In this study, the primary goal was to observe the effects of urbanization on bird species diversity and composition of native and non-native species in Arcata, California. Methods include fixed radius 75-meter point counts for ten minutes, within thirty predetermined study sites, where I counted bird species and the abundance of birds, landscape features (e.g., building density), along with noting any human activity that may occur. I hypothesized that non-native species would increase with increasing building density. In conjunction with that species diversity would decrease with building density.
