Bird cage where the bird doesn't exist

It is said that the bush warbler suits the plum tree from of old. As for that, there are a lot of cases of "It is White-eye in the plum tree". The bush warbler comes to the branch for plum blossoms because it likes nectar. But it rarely shows the appearance, because a genuine bush warbler is cautious.
I feel it poor that white-eye which has a delicate appearance is mistaken for a warbler. I was surprised to read the article that White-eye with the sweet voice was sold for millions of yen the other day. I hear that "Kyoumei Association" that competes for the cry are opened in various places. Therefore, poaching will prevail, and the capture of the appreciation purpose be prohibited.
It was only White-eye now though capture for appreciation had been admitted by seven kinds of birds such as bush warblers and larks before. I hear that the buying and selling of high price will have become a gang's money source part though the person who wants to enjoy keeping it might be regrettable. With this, White-eye is also poor.
There is a story of "Bird cage where the bird doesn't exist" in Reynard's famous "Natural History Magazine".
A certain man bought the bird cage. In the cage, there is a glass where a true plate of the nest and the grass made from cotton and fresh water were put in. Nevertheless, there is no essential bird.
He says asking in this way. "When I put one bird in this cage, the one cannot escape. I would like the one be free. "It is queer resistance to the confinement of the bird in the cage.
There is a person who wants to keep, or who want to observe outdoors.
The way to express love to the bird is various for man.
The words of Mr.Nakanishi Godo who is known by wild bird research were recalled.
