    Abstract:

    s: A highly pathogenic avian influenza (HPAI) H5N1 infected by whooper swans (Cygnus cygnus) and other wild ducks outbroke in early 2015 at Sanmenxia Reservoir Region, China. In order to strengthen the avian influenza surveillance and prevention, we summarized the data of wintering whooper swans population surveys in 2010 and 2015, and analyzed the fidelity on wintering sites based on the color making resightings of whooper swans. A total of 119 individuals resighted at Sanmenxia were confirmed from 19 lakes at the northern and central Mongolia. Meanwhile, whooper swans also showed the better fidelity to Sanmenxia wintering sites, which may be related to its habitats suitability and food richness. According to our survey results, the numbers of wintering whooper swans population at Sanmenxia increased significantly in recent years, especially reached 6,317 individuals in early 2015, and many whooper swans at other wintering site were attracted here, as a result of the better water quality through the diverting Yellow River to Sanmenxia Reservoir and abundant corn food raised by local people, so it is assumed that the HPAI outbreak maybe related to higher population density. Finally, it is suggested that the local government should take effective measures such as establishing a new suitable habitat, to promote population dispersal of whooper swans.
