Research Interest: My dissertation research focuses on the causes and consequences of nest site selection in songbirds. I am ultimately interested in fitness consequences associated with nest site choices, and I am planning on interpreting my results in the context of individual nest site fidelity in order to make inferences about the adaptiveness of nest-site preferences. I am interested in understanding the ecological and environmental basis of nest site selection, and I examine how interspecific competition, nest predation, and microclimate influence nest site selection in open-cup nesting songbirds. I study the sordida subspecies of the Orange-crowned Warbler on Santa Catalina Island. I use an experimental approach to assess the relative importance of interspecific competition and nest predation on the selection of nest sites. I also collect detailed microclimate measurements at nests to identify the potential physiological costs of nest site selection.
