黃蹼洋海燕（學名：Oceanites oceanicus）是海燕科的一種小型海鳥。是全球最廣為分佈的鳥類之一，主要生活在南半球的極地附近，夏季也會向北遷徙到北半球。估計全球有超過五千萬對黃蹼洋海燕。^[2]黃蹼洋海燕的英文名為Wilson's storm petrel，用以紀念一位美籍蘇格蘭鳥類學家Alexander Wilson。

外觀

黃蹼洋海燕是一種小型海鳥，體長16-18.5厘米，翼展38-42厘米。除了臀部和側腹部為白色之外，其餘全身羽毛均為深棕色。黃蹼洋海燕的翼下有明顯的淺色條帶狀紋路。^[3]指間的蹼呈黃色，亞成體的蹼上有黑色斑點。^[4]^[5]

分佈

黃蹼洋海燕在南極洲的海岸線及附近島嶼上繁殖。非繁殖期時，他們則是生活在大海上，當南半球的冬季來臨時則會北上。相比太平洋，他們在大西洋更加常見。在非繁殖期時，黃蹼洋海燕是一種典型的遠洋鳥類，再加上他們的繁殖地處南極，因此人們平時很難在陸地上看到他們。

行為

和其他很多鸌類一樣，黃蹼洋海燕常貼近海平面低飛，捕食海面附近的獵物。即使風平浪靜，他們也能利用海浪鼓起的微風飛行，並使用長腿幫助穩定身形。^[6]黃蹼洋海燕是高度群居的動物，也會跟隨海船飛行。當他們覓食時會發出輕微的吱吱聲。他們主要以海面的浮游無脊椎動物為食，很少跳入水裏抓捕獵物。有時也會捕獵3-8厘米的小魚。^[7]

黃蹼洋海燕的平均體重為40克，是南極最小的溫血動物。^[8]他們在靠近大海的岩縫或小洞穴里築巢繁殖，一次只產一枚卵。^[9]有時候，鳥巢會被積雪覆蓋而被毀，甚至有時幼鳥也會因此死亡。在繁殖地，黃蹼洋海燕是嚴格的夜行性動物，甚至還會避免在月光明亮的夜晚外出，以逃避鷗和賊鷗的捕食。雌雄親鳥均會餵養幼鳥。成鳥可以通過氣味在黑暗中找到自己的巢。
