I am interested in how the spatial distribution of resources and conditions may affect patterns of territory settlement and fecundity in birds. My current research examines these patterns in Ash-throated Flycatchers (Myiarchus cinerascens) among four vegetation types in the eastern Mojave Desert. In this system, I am determining how the distribution of food, nest sites, climate, and nest predators vary between and within these four vegetation types. My goal is to determine whether important differences that account for patterns of settlement and fecundity occur within or between these vegetation types.
