Preliminary Studies on the Ecological Types and Geographical Distribution of Birds in Zhejiang.

There are 410 species of birds recorded from Zhejiang, belonging to 19 orders, 63 families, and 203 genera. A zoogeographical analysis of the avifauna shows that there are three kinds of components: species beings entirely or mainly distributed in the Palaearctic realm, species beings distributed in both the Palaearctic realm and the Oriental realam, and species beings entirely or chiefly distributed in the Oriental realm. The avifauna of Zhejiang may be divided into six zoogeographical provinces: (1) the northern plain province, (2) the west-northern hill-mountain province, (3) the central basin province, (4) the eastern hill province, (5) the southern mountain province and (6) the coast-island province. It belongings to Central China Region of the Oriental realm with some transition and mixed features of North China and South China. From north to south, the species of the Palaearctic realm decrease and the species of the Oriental realm increase gradually.
