中文摘要 | 本研究針對東沙島唯一留鳥白腹秧雞進行繁殖行為調查。我們利用回播反應法調查白腹秧雞繁殖對在東沙島的分布情形,並透過紅外線攝影機記錄出現在給水站的離巢幼鳥。結果發現2015年繁殖季全島至少有46對白腹秧雞配對繁殖,分布幾乎遍佈全島。紅外線攝影機錄得每窩平均離巢幼鳥數為2.8±1.5隻(n = 21),且有4個樣點曾記錄到疑似第二窩的幼鳥。東沙島白腹秧雞的繁殖季從3月一直持續到10月,遠長於其在台灣的繁殖季3-7月,這也讓第二窩的出現越發可能。至於目前在東沙島上發現的白腹秧雞都屬當地留鳥或是有一部分為候鳥則有待進一步研究調查。 |
英文摘要 | This study focuses on the reproductive behavior of the White-breasted Waterhen Amaurornis phoenicurus, the only resident bird species on Dongsha Island. We used playback and applied infrared video cameras to investigate the response of waterhen breeding pairs and monitor fledglings around birdbaths on Dongsha Island. We found at least 46 breeding pairs of White-breasted Waterhens that spread across almost the entire island. According to video recording, average fledgling number was 2.8±1.5 chicks per nest (n = 21) and suspected second broods were found at four monitoring points. The breeding season on Dongsha Island extended from March to October, three months longer than that of mainland Taiwan. The long breeding season might enhance the occurrence of second broods. However, the residence status of waterhens on Dongsha Island is still unsolved. Further study will be needed to check if any migratory population appeared on the island. |
