海鹦，又名海鹦鹉，即海鹦属（Fratercula）鸟类。牠们是远洋海鸟，会潜入水中觅食。牠们会一大群的在悬崖或岛屿上繁殖，并会在石缝间或泥土中筑巢。其下的花魁鸟及角海鹦都是分布在北太平洋，而北极海鹦则分布在北大西洋。在冰岛上，就住有约1000万只北极海鹦。最大的群落是在冰岛的韦斯特曼纳群岛。于2009年，科学家估计当地就有110万个巢穴，而其数量就达400万只。

所有海鹦主要都是呈黑色或黑白色，身体粗壮，喙很大。繁殖季节时，牠们的喙会变得鲜艳；过后喙会变得细小及沉色。牠们短小的翼适合游泳。牠们在空中会频密的拍动双翼，达至每分钟400次。

Puffins are any of three small species of alcids (auks) in the bird genus Fratercula with a brightly coloured beak during the breeding season. These are pelagic seabirds that feed primarily by diving in the water. They breed in large colonies on coastal cliffs or offshore islands, nesting in crevices among rocks or in burrows in the soil. Two species, the tufted puffin and horned puffin, are found in the North Pacific Ocean, while the Atlantic puffin is found in the North Atlantic Ocean.
