Abstract.--Seven species of gulls were recorded during a six-year study (1997-2003) of gull populations along the west coast of Trinidad. An estimated 4000-5000 Laughing Gulls (Larus atricilla) wintered annually in western Trinidad, with the population peaking in February and less than 10% remaining during the northern summer. Up to 13 Lesser Black-backed Gulls (L. fuscus graellsii) wintered in Trinidad, with a few lingering during summer. Very small numbers of the remaining species were recorded: Black-headed Gull (L. ridibundus), Franklin�s Gull (L. pipixcan), Kelp Gull (L. dominicanus), Ring-billed Gull (L. delawarensis) and Sabine�s Gull (Xema sabini). Trinidad�s west coast provides crucial habitat for many waterbirds and is perhaps the most important locality in northern South America for wintering gulls, which are attracted by the fishing industry. |
