St Helen's, Isles of Scilly of kittiwake ("Rissa tridactyla") on the eastern cliffs, while Parslow (2007) records a large colony of lesser black-backed gull ("Larus fuscus") and a small colony of puffin ("Fratercula arctica"). The Seabird 2000 breeding seabird survey recorded five occupied nests of Manx shearwater ("Puffinus puffinus"). Foreman's Island () is a low-lying island on the south side of St Helen's Pool between Teän and Tresco. It is one of a group of rocks and islets of importance for breeding seabirds. The common froghopper ("Philaenus spumarius") has been recorded on Foreman's. Men-a-vaur () is to the north-west of St Helen's and consists of
San Benedicto Island location where several seabirds of the tropical Eastern Pacific come to breed. Taxa breeding on San Benedicto are: The nearly extinct Townsend's shearwater ("Puffinus auricularis") does not seem to breed on San Benedicto, but can sometimes be seen feeding offshore. Given that there are no invasive species on San Benedicto and also no predators apart from the frigatebirds, the island might be highly suitable for establishing a new colony. Indeed, it bred here before the 1952 eruption; shearwaters are highly conservative in choosing their breeding locations, which explains why San Benedicto has not yet been recolonized.
