My research focuses on the ecology and behavior of migratory passerine birds in their north temperate breeding areas in New England and their neotropical wintering quarters in the Caribbean and Central America. Our current research examines climate effect on bird distribution, abundance, and demography and will contribute to our understanding of the factors affecting neotropical migrant bird populations, some of which are currently declining.
