Bahamas National Trust and Wildlife Biologists assess the Seabirds of the Cay Sal Bank, The Bahamas

Recently the Society for the Conservation and Study of Caribbean Birds, Biodiversity Research Institute (BRI) and the Bahamas National Trust (BNT) came together in a major effort to assess the seabirds of the Cay Sal Bank—the Nassau Guardian reports.

The Cay Sal Bank, a remote and rarely visited island group in the southwestern corner of the Bahamas archipelago, is one of the largest atolls in the world. Human inhabitants have established permanent settlements on only two of the hundreds of cays and rocks on the Bank. Biodiversity Research Institute( BRI) instituted a special Science Expedition from May 26 – June 1, 2012 this year to allow scientists and volunteers to estimate the number of breeding seabirds on the Cay Sal Bank.

The Seabirds of the Cay Sal Bank Expedition was BRI’s inaugural Ecotour BRI’s unique new Ecotour program will allow participants to join research biologists on scientific expeditions in locales around the world. Groups will include a mix of experienced wildlife biologists and interested participants

Participants lived aboard the Sea Explorer, a 65-foot sailboat, chartered by Blackbeard’s Cruises, that accommodated 18 passengers in rustic, bunk-style sleep quarters. The ship’s crew provided three meals a day plus beverages.

Working alongside Biodiversity Research Institutes’ wildlife biologists and ornithologists, as well as guest biologists and conservation experts, the expedition participants make important contributions to science while exploring breathtakingly beautiful islands.

Caribbean Seabirds

Thousands of seabirds nest on the Cay Sal Bank; the area is designated as an Important Bird Area by the Bahamas National Trust and Birdlife International The seabird colonies here have never been properly documented, however they include significant portions of the region’s seabird populations. As we strive to halt the decline of seabirds in the Caribbean, it is critical for us to know the size and status of these large populations.

The goal of the expedition was to locate and carefully estimate current numbers of breeding seabirds, including: Audubon’s Shearwaters, Brown Boobies, Sooty Terns, Bridled Terns, Brown Noddies, Least Terns, Roseate Terns, Royal Terns, and Sandwich Terns.

The expedition, visited three major island groups—Cotton and Anguilla Cays in the southeast corner of the Bank, the Double-Headed Shot Cays on the western side, and the Elbow Cays in the southwestern corner. At each stop, the group divided into teams, each led by an experienced field biologist. Teams set up permanent census plots to document the populations and enable monitoring of the health of the populations with future surveys. All of the fieldwork was voluntary.

The expedition was led by:

William A. Mackin, Ph.D., who specializes in the conservation of Caribbean seabirds. He earned his doctorate (UNC-Chapel Hill) studying the behavior of Audubon’s Shearwaters and other seabirds in the Exuma Cays. In 2010, he worked in The Bahamas to determine if oil from the Gulf of Mexico was polluting the Cay Sal Bank; that experience inspired him to promote ecotourism to this amazing island group.

Lisa F. Eggert, M.S. is the director of BRI’s coastal bird program and a Ph.D. candidate at Clemson University. Since 2010, Lisa has been leading studies of health and movement of seabirds affected by the DeepWater Horizon oil spill. She and her Ph.D. advisor, Dr. Patrick Jodice, have partnered with Dr. Mackin to track the movements and health of seabird populations in the Bahamas since 2008.

Also participating in the expedition were BNT Science Officer Predensa Moore and BNT Warden (Grand Bahama) David Cleare. Volunteer biologists and conservation professionals included Lisa Sorenson PhD and Ann Sutton PhD of the Society for the Conservation and Study of Caribbean Birds, Michael Sorenson PhD, Boston University, and Jeff Gerbacht Cornell Lab Ornithology.

  1. I was on the navy ship hms ulster in 1957 when we visited cay sal and then it was not a place to be due to sand flys etc,how is it now?
