Hokkaido is one of the important stopover points for migratory shorebirds such as sandpipers and plovers. Epidemic research on West Nile virus and haematozoa infections in migratory shorebirds was conducted between 2006 and 2010 in marshes and lakes in Hokkaido. Shorebirds were captured using mist nets and released once samples were collected. This data set provides 282 occurrence data of 35 avian species.Sampling Description
Study Extent
Shorebirds were captured in marshes and lakes in Hokkaido during summer and autumn from 2006 to 2010. Mist nets were set at Lake Komuke, Shunkunitai, Kushiro-shitsugen, and Lake Utonai. Two individuals of Scolopax rusticola from Cape Erimo and Shirahama Akkeshi-cho were also included in the data set.Sampling
Shorebirds were captured using mist nets with authorization from Ministry of the Environment, Japan. The nets were set at night to make them nearly invisible. To ensure the safety for captured birds, the nets were checked every 30 minutes to 2 hours according to weather conditions and temperatures as well as tidal variations. Birds were released as soon as samples were collected. Dates that we opened mist nets were recorded as captured dates. The data set includes two individuals of Scolopax rusticola, which were a dead bird found in Cape Erimo and a weakened bird found in Shirahama Akkeshi-cho.Quality Control
Georeferencing instructions and recommmendations by Chapman and Wieczorek (2006) were used to estimate uncertainties of geographical coordinates.Method steps
- Individual records consisted of 1,737 banded and 37 non-banded birds were organized into species occurrence data using a MySQL database. Same species captured in the same locality at the same event date/period (1 to 3 days) were added up as "individualCount". The individuals banded and recaptured on the same event date/period were counted as 1. Geographic coordinates and uncertainties were calculated using gazetteers such as Google Maps and the Geospatial Information Authority of Japan Map following procedures described in Chapman and Wieczorek (2006). A centroid of a polygon calculated with ArcGIS 10 was used as geographic coordinates for Lake Komuke and Lake Utonai, since polygon data for lakes were available at the National Land Numerical Information download service (Ministry of Land, Infrastructure, Transport and Tourism, Japan).
