Taiwan Matzu, Mainland China Jiushan and Wuzishan islands are the four areas confirmed to have their breeding populations. Chinese Crested Terns co-habitat with Greater Crested Terns (T. bergii) and also migrate and over-winter together. In 2011-2014 we found both terns abandoned their breeding nests at the beginning of the breeding season, indicating the breeding population and environment are not very stable in Matzu. However, we only have very limited knowledge on their breeding population dynamics, breeding and feeding ecology, habitat selection and resources competition which caused limited effects on planning conservation policy and management strategy. Therefore, this study will be from conducting basic research, furthermore, to apply on monitoring and conservation strategies in order to maintain the tern biodiversity. This study will be conducted in Matzu Island Tern Refuge, Penghu Columnar Basalt Nature Reserve, Jiushan and Wuzishan Nature Reserve. The purposes of the study are (1) testing the breeding site selection mechanism of Chinese Crested Tern and Greater Crested Tern by social attraction and vegetation modification at four breeding sites; (2) studying the food and nest site competitions or segregation condition during breeding season between both terns; (3) constructing the population dynamic model of Chinese Crested Tern by population monitoring and banding-re-sighting records. We expect to be able to establish the base line data for both terns in terms of breeding, feeding and migration ecology, and population dynamics. Hopefully we will be able to set up and execute the conservation action plan for the terns.繁殖生態黑嘴端鳳頭燕鷗韭山列島海洋生態自然保護區五峙山列島鳥類保護區鳳頭燕鷗馬祖列島燕鷗保護區澎湖玄武岩自然保留區Breeding ecologyChinese Crested TernJiushan Nature ReserveWuzishan Nature ReserveGreater Crested TernMatzu Island Tern RefugePenghu Columnar Basalt Nature Reserve
