This study was conducted for the purpose of understanding the variations in the characteristics of geese (Anser spp.) resting and feeding in the Nakdong Estuary area, Korea during the 1990s and 2000s. The dataset was collected through two long-term monitoring periods, one of which was in the early 1990s (May 1989-April 1993) and the other is in the mid-2000s (May 2002-April 2008). During both periods, a total of 4 species and 82,239 individuals of geese (Anser spp.) were observed: 74 Swan Geese (Anser cygnoides), 73,374 Bean Geese (Anser fabalis), 8,786 Greater White-fronted Geese (Anser albifrons), and 5 Snow Geese (Anser caerulescens), respectively. In the early 1990s, 14,860 individuals were observed: 3 Swan Geese, 11,270 Bean Geese, and 3,587 Greater White-fronted Geese. In the mid-2000s, 67,379 individuals were observed: 71 Swan Geese, 62,104 Bean Geese (Anser fabalis), 5,199 Greater White-fronted Geese, and 5 Snow Geese. The average numbers of observed individuals in five different areas were 9089.67 in Daemadeung, 381.83 in Jangja-Shinjado, 97.00 in Saja-Doyodeung, 1412.67 in Lower Ulsukdo and 248.67 in Ulsukdo, respectively. The total average of these 5 areas was 2,245.97. There was a significant difference among the monitoring areas (Kruskal-Wallis test, x<SUP>2</SUP> =17.693, P<0.05). In particular, the observed individuals were larger in Daemadeung and Lower Ulsukdo than in the other three areas.
