Resumen

Knowledge of the temporal distribution of waterbirds species is essential to take measures for the conservation of their habitat, since they and their environment are the fundamental natural resource for environmental sustainability. The present study was made in the section called "vado" from the San Pedro River in Meoqui town; this river is included in the List of Wetlands of International Importance. A multivariate analysis was realized to determine the association between environmental variables and the frequency of distribution of species, analyzing the variability in the distribution of birds and environmental conditions of preference, and for potential clusters of bird species. With the total of 30 species observed, belonging to 19 genus, it was observed that the month with the highest abundance was January due to the arrival of winter migratory birds. It can be seen that the species (Agelaius phoeniceus, Anas acuta y Butorides virescens) they are birds with different behavior, as they are species that prefer warm temperatures with high precipitation. Temperature, wind speed and precipitation are the main environmental variables, which determine the temporal distribution of waterbirds. So the conclusion is exists an association between the frequency of sightings of waterfowl and months of the year.
