资源简介：
Waterbirds were observed during breeding season in the Copper River Delta Area of Alaska. These data include 14 unique taxa observed over a seven-year period. In 1964, an earthquake changed the wetlands of this area, uplifting them by 1.9 meters and draining large areas. Goose breeding populations have since been in decline. These data provide occurrence information at nests.
