The United States Geological Survey (USGS) has been working in partnership with the United Nations Food and Agricultural Organization (FAO), the Wildlife Conservation Society Global Avian Influenza Network for Surveillance (WCS-GAINS) and Wetlands International (WI) to study the role of wild birds in the geographic spread of highly pathogenic avian influenza (HPAI) H5N1. In September 2007, we partnered with the Institute of Zoology of the National Academy of Sciences of Kazakhstan for a study at Kyzykol ("Red Lake") in southern Kazakhstan. Our aim was to capture and test wild waterbirds for the presence of avian influenza virus and fit 10 ducks with satellite transmitters in order to track their movements during the autumn migration period.
During our mission to Kazakhstan we deployed satellite transmitters on 7 Mallard (Anas platyrhynchos), 2 Ruddy Shelduck (Tadorna ferruginea), and 1 Gadwall (Anas strepera). The birds were captured using mist nets, catching individuals during dawn and dusk flights. USGS scientists from the Western Ecological Research Center and Alaska Science Center will monitor the satellite movement data to better understand migration chronology, routes, and potential risk factors associated with the spread of HPAI H5N1.
