Why is the crow in Chongwenmen, Beijing missing?

There is no clear official information about the reasons for the disappearance of crows in Chongwenmen, Beijing. But there are some possible explanations: 1. Environmental change: the crow's habitat may have changed, which may be due to the increase of buildings, the decrease of greening and the decrease of food sources in this area, which affected the crow's habitat and led to its migration from this area.

2. Epidemic disease: It is possible that there is an epidemic disease in this area, which leads to the decrease or departure of crows.

3. Control: Another possibility is that the municipal government takes measures to control the number of crows and move crows to other areas in order to maintain the cleanliness of the urban environment and prevent crows from causing inconvenience to citizens' lives.

Whatever the reason, we should respect the change of nature and the decision of urban management, and at the same time make our own contribution to environmental protection and wildlife protection.
