New records of Van Rossem’s Gull-billed Tern (Gelochelidon nilotica vanrossemi) nests in the Coast of Jalisco, Mexico

We report new nesting sites for the Van Rossem’s Gull-billed Tern (Gelochelidon nilotica vanrossemi) at the Agua Dulce and XolaParaman lagoons, in the coast of the state of Jalisco, Mexico. We first recorded the nests on 19 June, 2013 and monitored them at two-week intervals until 2 August, 2013. We found eight nests in the Agua Dulce lagoon and 16 in the Xola-Paraman lagoon. These new records expand the known nesting range of the Van Rossem’s Gull-billed Tern along the Pacific coast, from San Diego, California to the state of Colima in Mexico.
