In order to know the ecological groups and diversity of birds in the Furong Island, the species, ecological groups, geographical types, residence types and diversity of the birds in the Furong Island are studied based on the bird investigation in the Furong Island in September 2019 by means of site observation method. The results show that a total of 31 species of 15 families and 5 orders of birds were recorded in the investigation, of which 7 species belong to the national second-level protected birds and 1 species is listed in the Appendix III of the The convention on international trade in endangered species of wild fauna and flora resolutions in effect of the conference of the parties.

The dominant species of birds in the Furong Island are mainly Larus ridibundus, Hirundo rustica and Passer montanus.
