Bird Xiang Ji!The TAs of the Jiuzuansha were dispatched

Recently, the relevant staff of the Jiudu Sand Wetland Nature Reserve Management Affairs Center took high temperature and heat, with monitoring equipment, sitting on a simple "convertible" ship, flying in the peaks and valleys, and conducted a special survey on water birds.

Due to its lonely and unique geographical location away from the mainland, it is not easy to launch a water bird survey in the nine -stage sand. The accessability of the investigation area and the distribution of water birds are affected by the rules of the tide.

In order to more scientifically understand the number of water and birds and its cycle changes, and the results of the investigation are comparable. The investigators need to try to be as similar in the tidal conditions as much as possible. As the tide rises and the tide is rising, the sandy is hidden, and various types of water birds are playing with water, observing with the naked eye and lens, and counting birds.

In this bird survey, the staff of the Jiuzuansha followed the fixed survey route, sometimes holding the telescope, observing the water birds where the beach stopped for food, and sometimes carried a long -focus camera to capture the bird shadow flying in the sky. Sometimes Buried the professional bird illustrations and reference books, compared with the characteristics of each bird, record the birds and quantities seen on both sides of the survey route.

The survey records a total of thousands of birds, mainly categories, and there are many gulls and herons. These include the national first -level key protection wildlife black -mouth gulls and national second -level key protection wildlife Daibinba.
