| Outline of Final Research Achievements |
Nakanokamishima, located in the Yaeyama Islands, is the breeding habitat for six seabird species. The long-term population trends of the Brown Booby and some parameters, being breeding success (79%) and annual survival rate of adult (92%), for the simple model of its trends were analyzed. Based on bio-logging, habitat of breeding was within radius of ca. 100km, and habitats of the non-breeding was from the southern Philippines to Papua New Guinea, or on the Yellow Sea. Although, the logger was attached to fledglings to explain the low survival during young (survival rate before breeding; 28%), we could not recapture them which returned to the island. Furthermore, non-breeding habitat of the Brown Noddy and the geological variation of the body size of the Streaked Shearwater were explained. It is necessary to elucidate the habitats of small species for the conservation of the island ecosystem in the future.
