Disclaimer: Lack of a statistical sampling design, differences in field methods among countries and colleagues, lack of rigorous synchronization of survey dates, changes in volunteer survey personnel, variability in personnel experience and survey effort, and changes in survey locations within countries are all limitations of the LAC Waterfowl Surveys program.  As a result, caution must be exercised in attempting to estimate and draw inferences about population trends using data from these surveys.  Any such attemps should be made in close consultation with DU and the country experts who have knowledge of specific limitations of these data for individual countries and species.
