Our sustainability project has two sites. One of them is the secondary forest. It was farmland more than ten years ago. It was abandoned and became the secondary forest. There are so many thin trees and the forest is relatively dark. For two years, we have thinned some trees to make the forest light and airy.

As you can see and listen to the above video, many birds are living there.

One of my favorite birds is the Japanese green pigeon.

You can listen to her song at the beginning of the video. Her song is a unique and beautiful color she has.(wikipedia)

Please enjoy the songs of our friends in the forest for a while.
