Why does Typhoon Tian appear rare birds?

He Xin, an associate researcher at the Shanghai Nature Museum, introduced that among the birds of birds, people often call some birds who mainly live in the sea and rarely fly to the sea as seabirds.鲣, 鲣 鹱 以及 鹱, and some marine ternovies.

In the process of typhoon movement, the seabird may be affected by the enhancement of the wind of the typhoon. Before the typhoon comes, it can still find the windshield when flying actively. This is why some seabirds appear on the coast a few days before the typhoon came.

Another case is that when the seabirds can no longer avoid the typhoon and are unable to fly against the wind, they will be involved in the typhoon cantilever. At this time, in order to save their lives, they may work hard to fly smoothly until they enter the typhoon eye area with relatively weakened wind power. And with the typhoon eyes, they finally landed.

After landing, the wind of typhoon weakened, and these seabirds had the opportunity to escape the control of typhoons and find a suitable area rest on land. At this time, waters with large area, good environment, and safe stops have become their best choices for their rest and replenishment of physical strength.

Although the Century Park is not close to the seaside, the green area is large enough, and the water surface of Jingtian Lake is wide, so in addition to some common birds, rare birds appear from time to time.
