The overall objective of this research project is to provide a better understanding of population variation and the behavioral mechanisms of winter population regulation of neotropical migratory birds wintering in three habitats across an altitudinal gradient in the Dominican Republic. The specific objective of this research project is to address the need for habitat-specific demographies in a study of migrants wintering in three critically threatened and migrant-rich habitats—coastal spine forest, dry broadleaf forest, and pine forest—along an altitudinal gradient in Hispaniola.Approach:
In each habitat, specific fitness indices such as home range size, site fidelity, overwinter turnover, and annual return rates will be quantified and compared by species, sex, and age class. I also will use behavioral observations to determine what foraging and social strategies are used by migrants in these habitats, whether these vary by sex and age class, and how social behavior (particularly association with mixed-species foraging flocks) relates to measures of fitness. These measures will allow us to compare fitness values between habitats on Hispaniola and other study islands.Supplemental Keywords:
