Why did the first-class protected animal bustard "move" from Hancheng to Huayin?

On January 15, the reporter received news from the Huayin Forestry Bureau that more than 300 great bustards, a national first-class protected animal, were found near the Changjian River, a tributary of Nanshan In Huayin City. According to experts, about 300 bustards migrate to Shaanxi every year, most of which previously spent the winter in the Zhichuan section of the Yellow River wetland Hancheng. Therefore, the previous migration site of the great bustard population found in Huayin may have been in the Hancheng section of the Yellow River wetland.

This year's migration season, why do migratory birds fly to Huayin? The reporter learned that Hancheng City recently launched the construction of the Yellow River bank control and guidance project in the core area of the Yellow River wetland, so it has a certain impact on the beach area where migratory birds are active.

It is understood that if migratory birds are affected by the surrounding environment and fly to other areas, it is difficult to return to their original places thereafter. Some bird protectors pointed out that it is feasible to implement staggered peak activities and carry out construction after the end of the migratory bird migration season?

The Hancheng section of the Yellow River wetland is one of the important migratory bird migration sites in China, and before that, there were gray cranes, bustards and other nationally protected animals migrating here every year for winter. However, in recent years, the number of local migratory birds has decreased, and most of them have flown to Shanxi, a tributary of the Yellow River such as the Wei River, and on the east bank of the Yellow River to feed.

It is understood that Hancheng City implements strict control over the core area of the Yellow River wetland, and does not allow crops to be planted in the core area of the Yellow River wetland, while the great bustard and the gray crane waiting birds feed on crops such as wheat seedlings and beans.

Relevant experts pointed out that the focus of wetland protection is to crack down on illegal sand dredging and illegal construction in wetlands, but it cannot be overcorrected and closed, and moderate cultivation will help the survival of migratory birds, so that the wetland ecosystem can reach a certain balance.
