Our goal is to enhance the understanding of seabird ecology in the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. We study the breeding biology, survival, and foraging and spatial ecology of nearshore and pelagic seabirds at sea or on their breeding grounds.

Our most recent studies focus on distributions and habitat use at sea, including foraging trip characteristics and how these differ throughout the annual cycle, foraging site fidelity at sea, migration routes, interactions of seabirds with energy infrastructure in the offshore environment, and use of Marine Protected Areas. We do this by using the full range of tracking technologies that are available including satellite tags, geolocators, GPS, as well as color banding and molecular markings.

We work closely with the Atlantic Marine Bird Cooperative, the Gulf of Mexico Avian Monitoring Network and BirdsCaribbean. Together, our research extends from the South Atlantic Bight of the U.S. through the Caribbean and Gulf of Mexico. The birds we study disperse throughout the North Atlantic and, as such, our research uniquely covers a significant portion of our Earth's oceans.
