Wetlands are one of the most important ecosystems worldwide due to the great biologic diversity that they harbor and the resources and ecosystem services that they provide; however, their conservation is seriously threatened. Waterfowl are one of the most representative components of wetland biodiversity and the study of their communities is necessary to establish protection priorities appropriately. In this study, we describe the species richness and relative abundance of the waterfowl community of an artificial wetland in Mexico State which we visited from August 2010 to August 2011. We found 23 species, most of which belong to the Anatidae (ducks) and Ardeidae (herons) families and we recorded an accumulated abundance of 25,220 individuals. We performed an accumulation curve and we used Clench’s model which estimated 24 species; thus, we observed 95% of the predicted species. The arrival of migratory species contributed substantially to the increase of the species richness and the abundance of individuals, especially from October to March. We consider that the species richness and the abundance that we recorded, including observations of rare species, species reproducing, and species under a conservation category, are indicative of the great ecological value of this wetland despite its limited size. Therefore, it is relevant to assess ecological features of natural and artificial wetlands, including waterfowl communities, in order to improve the conservation actions in this region.
