At lower spatial and temporal scales, I am interested in studying how human disturbances (e.g., fragmentation of of otherwise "good" forests, urbanization, general degradation of habitats, availability of supplemental food) affect birds as individuals, populations and communities. Ecological (e.g., radio-tracking, surveys) and genetics techniques are combined to probe such questions.
