Abstract

The importance of Laguna de Bustillos, Chihuahua, Mexico for waterbirds was evaluated during the 2011–2012 nonbreeding season. Thirty-seven percent of all birds were light geese (Chen caerulescens and C. rossii) and 44% consisted of three other species (Anas clypeata, Grus Canadensis, and Anser albifrons). Our data contrast with the historical counts of birds by the U.S. Fish and Wildlife Service using aerial surveys and may reflect recent land-use changes. Given the fact we observed some species in numbers that were far greater than previously recorded, our results provide evidence of the increasing importance of Laguna de Bustillos for wintering waterfowl.
