説明

As a basic study on biological concentration of organochlorine compounds and heavy metals in the Eastern Great White Egret, Egretta alba modesta, the present investigation was carried out to examine the biometry of growth and food of young during the period from the inward (April) to outward (August) migration in Korea. In the chicks, the body weight, whole body lipid and moisture content and relation of tissue and organ weights to the body weight changed with growth, especially with flapping and flying activity. In the adults, body weight, whole body lipid and moisture content fluctuated widely owing to migration and breeding; the relationship of tissue and organ weights to the body weight was nearly constant through the period. The chicks fed mainly on loaches in addition to frogs and insects; the size of the loaches eaten by the chicks increased as they grew, indicating that the more the chicks grew, the larger fishes they selected.
