Gulf of Mexico oil spill: 20110414-LAPS209_copy

Tulane University population ecologist Jessica Henkel sets up a net to catch migrating birds for blood, fecal and feather samples on Fourchon Beach in Port Fourchon, La., as part of a research project that is looking for long-term, not-immediately lethal effects from the oil spill on birds that stop along the Gulf Coast during their migration. “It's much easier to see a dead pelican on the beach” than it is to see more chronic population-wide effects, Henkel said.
