ทูตแห่งสวรรค์ : นกกระเรียนไซบีเรียตัวเล็กๆตัวหนึ่งเปลี่ยนแปลงไต้หวัน (ฟอร์โมซา) อย่างไร-ตอนที่ 4 ของ 4 ตอน

Due to global warming and climate change, the water level gets too high or too low in the habitat, so the White Cranes can’t find enough eelgrass to eat. Then they move out of their habitat center to look for food, causing conflict between humans and the cranes. This might be the reason their appearance has been newly recorded in the last two years in Japan, Taiwan (Formosa), and Hong Kong. In Spring, the cranes start to fly to the north, leaving Poyang Lake as their winter habitat and flying for 2,000 km towards the northeast to Momege Nature Reserve in Jilin Province of Northeast China.
