The Gulf of Mexico (GOM) contains a high density of oil and gas infrastructure and coastal development. It also has a rich assemblage of nearshore and pelagic seabirds. The region is of year-round importance to seabirds, including local breeding populations and breeders from distant locations that occur within the Gulf throughout the year. Because of its distribution patterns, behavior, and known sensitivity to chemical and oil contaminants exposure, the Brown Pelican (Pelecanus occidentalis) is a good indicator of species-level impacts from interactions with coastal and marine development. The species is widespread throughout the northern GOM and common during all phases of the annual cycle. Despite the species’ long history as a focus for conservation and restoration efforts, much of the information required to understand pelican population dynamics and habitat requirements (i.e., adult and fledgling mortality, dispersal, site fidelity, diet composition, foraging behavior, migration patterns, and nonbreeding habitat use) remains unknown or is poorly understood.
In this study, we used several unique research avenues to address questions regarding movement, habitat use, physiology, and reproductive ecology of brown pelicans. Our research encompassed six principal objectives: (1) assessing reproductive ecology; (2) assessing baseline habitat use by the species in this region, particularly individual and regional variability; (3) assessing baseline health and exposure to contaminants in this region, particularly individual and regional variability; (4) predicting overlap of pelicans with anthropogenic risk factors; (5) understanding pathways by which changes to adult movement patterns might influence reproductive ecology and how to best measure such effects in wild populations; and (6) assessing movement ecology in the context of interactions with key prey resources.
