Eastern Brown Pelicans nesting on Matagorda Bay, Texas. JLamb 2014.

Spatial ecology, breeding biology, and environmental stressors in the Eastern Brown Pelican

Our research focuses on obtaining information about populations of Brown Pelican (Pelecanus occidentalis carolinensis) breeding across the northern Gulf of Mexico and in the South Atlantic Bight of the U.S. This research is intended to address information gaps and provides baseline ecological information for Brown Pelican. 
 

To date, we have used tracking data to analyze preferred marine habitat characteristics and analyze individual and colony-wide variation in home ranges, habitat characteristics, and migratory patterns. We have also collected breeding data from several colonies across the South Atlantic Bight and Northern Gulf of Mexico including chick survival from hatch to fledge, chick body condition, chick stress levels, chick diet composition, and nestling provisioning rates. We have color-banded pelican nestlings and are conducting an ongoing citizen science effort (through the Project Pelican initiative) to re-sight color bands and investigate the dispersal patterns and survival of juveniles during their first winter.

Future analysis will focus on comparing health, contaminant loads, and stress across colony sites, determining genetic correlates of migratory behavior, and investigating drivers of local-scale variation in nesting success and chick survival.
