Abstract

|
|
|
The changes of pectoral muscle size (as an index of protein reserves) and fat reserves (as an index of lipid) were measured in wintering Dunlin during 1988 -1989 on two estuaries located in the south coast of Korea. The mean of lean mass of February population was greater(11.8%) than that of October population. SMI of October population was greater(4.5%) than that of February population and lipid index of October population also greater(1.6%) than that of February population. This show that the body condition of October population is better than February population. The mean of fat and protein reserves of 22 % of Dunlin arriving on October for their wintering were higher than that of others, this group seems to continue their migration to south further and 11% of the wintering population seems to starve during winter.
