The heron is the largest bird of the egret family in Korea.
Herons are summer birds that breed throughout Korea, although some winter in the south of the peninsula and on certain islands.
They generally inhabit rice fields, streams, and tideland areas, and eat frogs, fish and snakes.
The Breeding Ground of Grey Herons in Jincheon has been a breeding ground for egrets and herons mainly around the ginkgo tree in the Nowon-ri preservation area since the 1970s.
However, the tree is dying owing to the birds’ excrement, so only five or six nests occupied by medium and large-sized herons remain, while all the other grey herons and egrets have migrated to a neighboring forest.
The Breeding Ground of Grey Herons in Jincheon has been designated as Natural Monument (No.
13) to protect it from water pollution and a fall in the number of herons due to the decline of their food sources, including frogs and loaches, etc.
