large duck, to which they are unrelated. Their plumage is largely grey or black, and they have spear-shaped bills. Loons swim well and fly adequately, but are almost hopeless on land, because their legs are placed towards the rear of the body. Red-throated loon, Gavia stellata Pacific loon, Gavia pacifica (A) Common loon, Gavia immer Albatrosses Order: ProcellariiformesFamily: Diomedeidae The albatrosses are among the largest of flying birds, and the great albatrosses of the genus Diomedea have the largest wingspans of any extant birds. Yellow-nosed albatross, Thalassarche chlororhynchos (A) Black-browed albatross, Thalassarche melanophris (A) Southern storm-petrels Order: ProcellariiformesFamily: Oceanitidae The storm-petrels are the smallest seabirds, relatives of the petrels, feeding on planktonic crustaceans and small fish picked from the surface, typically while hovering. The flight is fluttering and sometimes bat-like. Until 2018, this family's three species were included with the other storm-petrels in family Hydrobatidae. Wilson's storm-petrel, Oceanites oceanicus White-faced storm-petrel, Pelagodroma marina (A) Northern storm-petrels Order: ProcellariiformesFamily: Hydrobatidae Though the members of this family are similar in many respects to the southern storm-petrels, including their general appearance and habits, there are enough genetic differences to warrant their placement in a separate family. European storm-petrel, Hydrobates pelagicus (A) Leach's storm-petrel, Hydrobates leucorhous Band-rumped storm-petrel, Hydrobates castro (A) Shearwaters and petrels Order: ProcellariiformesFamily: Procellariidae The procellariids are the main group of medium-sized "true petrels", characterized by united nostrils with medium septum and a long outer functional primary. Northern fulmar, Fulmarus glacialis Bermuda petrel, Pterodroma cahow (A) Black-capped petrel, Pterodroma hasitata (A) Fea's petrel, Pterodroma feae (A) Cory's shearwater, Calonectris diomedea Sooty shearwater, Ardenna griseus Great shearwater, Ardenna gravis Manx shearwater, Puffinus puffinus Audubon's shearwater, Puffinus lherminieri (A) Barolo shearwater, Puffinus baroli (A) Storks Order: CiconiiformesFamily: Ciconiidae Storks are large, heavy, long-legged, long-necked wading birds with long stout bills and wide wingspans. They lack the powder down that other wading birds such as herons, spoonbills and ibises use to clean off fish slime. Storks lack a pharynx and are mute. Wood stork, Mycteria americana (A) Frigatebirds Order: SuliformesFamily: Fregatidae Frigatebirds are large seabirds usually found over tropical oceans. They are large, black, or black-and-white, with long wings and deeply forked tails. The males have coloured inflatable throat pouches. They do not swim or walk and cannot take off from a flat surface. Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a
