The islands have a seabird colony, which is particularly important for the Arctic tern, numbers of which are nationally important; the roseate tern breeds occasionally in very small numbers. In 2018 two roseate tern chicks fledged here for the first time in a decade. The following species also breed: Atlantic puffin, black-legged kittiwake, common tern, herring gull and lesser black-backed gull.
