- GDESC:雌雄同型。虹膜黑褐色。嘴黑細長、尖端有極細小白斑。腳黑褐色。成鳥繁殖羽全身大致為白色，體下略沾粉紅色，背及翼灰白。黑色過眼線延伸至後枕、甚為醒目。停棲時尾端約與翼尖等長。飛行時，通體幾近白色，最外側初級飛羽外緣黑色。尾羽分叉深。幼鳥頭頂夾雜細黑斑，背及翼夾雜黑褐色雜斑及鱗斑，尾羽較成鳥短。典型海洋性鳥類，喜群居，多單獨覓食，主要在海上捕食小型魚類，於空中發現獵物後即俯衝入水捕食，也會由水面撈捕獵物。甚少到淡水河流、湖泊或內陸活動。4~8月常小群或與其他燕鷗築巢於無人島嶼礁岩上，巢位簡單、多半僅在地面凹處周邊堆以小石子或草枝，每巢1~2枚蛋，少數3枚。蛋呈乳白色、具不規則深淺褐斑，雌雄鳥共同孵卵及育雛，孵化期約20~27天。
  棲地介紹：海岸、河口、魚塭。
