My research involves quantifying connectivity of a Neotropical migratory songbird to assist in understanding how seasonal interactions influence individual- and population-level dynamics. New technology has allowed researchers to directly determine an individual’s location throughout the year using archival light-level geolocators. My research uses geolocators (light-level, GPS tags) and other methods such as stable isotopes to describe the extent of connectivity between breeding and non-breeding populations of migratory songbirds. My research uses both tracking technology and modeling approaches to determine how seasonal interactions operate throughout the annual cycle. Identifying connectivity of populations will provide information that will assist in understanding the ecology of migratory species, as well as help focus efforts for conservation.
