🐦Arctic Tern
北極燕鷗（學名：Sterna paradisaea）是屬於燕鷗科的一種海鳥。分佈於北極及附近地區，並於北極、歐洲、亞洲和北美洲靠近北極的地方進行繁殖。北極燕鷗是候鳥，每年经历兩個夏季，從其北部的繁殖區南遷至南極洲附近的海洋，之後再北遷回繁殖區（約24,000英里），這是已知的動物中遷徙路線最長的。 北極燕鷗體型中等，一般長33到39公分，翼展76到85公分。其羽毛主要呈灰色與白色，喙和兩腳呈紅色，前額呈白色，頭頂和頸背呈黑色，腮幫子呈白色。其灰色翅膀為305毫米，肩羽帶棕色。上面的冀背呈灰色，帶白色羽緣，頸部呈純白色，其帶灰色羽瓣的叉狀尾部亦然。其後面的耳覆羽呈黑色。 北極燕鷗只會照料和保護小部分的幼鳥。成體會長期養牠們的幼鳥，並幫助牠們飛往南方過冬。北極燕鷗壽命很長，大部分可活上20年。牠們主要吃魚和水生的無脊椎動物。此物種數量很多，約為一百萬個個體。
