Rufous-Bellied Pied Woodpecker, rarely seen in Korea, lives in one place the year round and some Rufous-Bellied Pied Woodpeckers fly to warm areas in winter. So, it is a mysterious phenomenon that this bird appeared on the shores of Lake Chon on Mt. Paektu which is low in temperature.

Tricolour Flycatcher has never come to the shores before.

This bird would stay in Southeast Asia in winter and come to Korea in April and May. It feeds on harmful insects while living at the foot of mountains or in the vicinity of rural villages.

It is unprecedented that such birds, which would live in comparatively warm areas, appeared on the shores of Lake Chon.

The said group confirmed that animals are able to live even in Lake Chon of Mt. Paektu, the lake formed at a volcano crater. In the course of intensifying its ecological observation, it watched in succession new animals, including seagulls which have appeared around the lake from the end of the 1980s when shoals of chars began to propagate there.

The discovery of Rufous-Bellied Pied Woodpecker and Tricolour Flycatcher added to the number of species of stationary or migratory birds found out so far by the group in the area of Mt. Paektu.

The facts go to prove that the area of Lake Chon on Mt. Paektu is turning in favor of inhabitation of animals.

At least 70 species of insects, feed of birds, can be seen on the shores of the lake in summer, and there are a lot of plankton and others.

Also, diversity of plants, including trees, and their thickness provide good conditions for bird inhabitation.
