Mapping waterbird distribution and migration in South America

Knowledge about the distribution and migration of waterfowl in South America is scarce. A considerable amount of information was produced over the past 15 years, although in general it is unpublished, disperse, and not easily accessible to technicians and decision makers who work in wildlife management and in particular in the monitoring of avian influenza in our region.


Action Description:


The objective of this action was to contribute to Global Avian Influenza Network for Surveillance (GAINS), with updated information on the distribution and migration of waterfowl in South America, through the mapping of 25 key species.

For that purpose, first we selected 25 species of waterbird, whose ecological and behavioral characteristics make them likely to sick and spread the disease (high-risk species). To compile information on these species we gathered information from countings, mainly based on the Neotropical Waterbird Census (1990-2006), but also incorporating other sources of information, such as literature, unpublished reports, specialist consultations, country lists, etc. Finally, the information collected was standardized and then used for mapping the distribution and abundance, seasonality and migration.

More information about the drawing up the maps process can be found in the Introductory Report.

The maps and factsheets of species are available in English, will soon be in Spanish. To access them you can use the following links:
