New records of waterbirds for the interior of Jalisco State: case Laguna de Sayula, Mexico

Abstract

Knowledge about birds in Mexico and their distribution is the result of many years of explorations in specific areas; despite of the effort done, in some regions of Mexico it is still unknown the composition and distribution; that is the case for inland wetlands, which represent wintering sites and migration routes for a great variety of waterbirds and terrestrial from Neartic region, as well as nesting sites for resident species. We highlight observations performed at Laguna de Sayula, Ramsar Site that are part of the results of a long term bird study with monthly sampling during five winter seasons. It is reported for the first time six new records at the wetland and some for the inland of Jalisco State (Dendrocygna autumnalis, Branta Canadensis, Sula leucogaster, Pelecanus occidentalis, Pluvialis squatarola and Charadrius semipalmatus) and reports of Anser albifrons and Anser rossii with few published records for the zone.
