Round Island Light, Isles of Scilly nests of Manx shearwater ("Puffinus puffinus"). Permission is needed from Trinity House to land on the island and only two botanists are known to have visited. The first, J. E. Lousley, in 1957, only recorded the invasive Hottentot fig ("Carpobrotus edulis"). Thirty years later, in 1987, Rosemary Parslow found much of the ground between the buildings and the cliff edge was covered in a carpet of purple dewplant ("Disphyma crassifolium") and Hottentot fig. She also recorded a small number of the expected coastal species. They were sea spleenwort ("Asplenium marinum"), bird's–foot trefoil ("Lotus corniculatus"), spear–leaved orache ("Atriplex prostrata"), sea beet
Black-vented shearwater central and southern California during the country's colder months. The black-vented shearwater is thought to feed on mainly small fish. This bird nests in burrows and caves; it is a colonial nester. In the past, this bird had been threatened by feral cats and other predators on its breeding islands, but the problem seems to have been largely eliminated. There is some loss of birds from commercial gill netting, and the species is classified as near threatened by the IUCN mainly due to the uncertain impact on it by the expanding fishing industry.
