This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of The Clements Checklist of Birds of the World, 2022 edition.
These birds are adapted to an aquatic existence with webbed feet, flattened bills, and feathers that are excellent at shedding water due to an oily coating.
Order: Caprimulgiformes Family: Apodidae Swifts are small birds which spend the majority of their lives flying.
They are small to medium-sized birds with compact bodies, short, thick necks and long, usually pointed, wings.
Variation in length of legs and bills enables multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.
Terns are a group of generally medium to large seabirds typically with grey or white plumage, often with black markings on the head.
Order: Phaethontiformes Family: Phaethontidae Tropicbirds are slender white birds of tropical oceans, with exceptionally long central tail feathers.
Order: Procellariiformes Family: Oceanitidae The southern storm-petrels are relatives of the petrels and are the smallest seabirds.
Order: Procellariiformes Family: Procellariidae The procellariids are the main group of medium-sized "true petrels", characterised by united nostrils with medium septum and a long outer functional primary.
Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.
Members of Ardeidae fly with their necks retracted, unlike other long-necked birds such as storks, ibises and spoonbills.
Order: Coraciiformes Family: Alcedinidae Kingfishers are medium-sized birds with large heads, long pointed bills, short legs and stubby tails.
Old World parrots are found from Africa east across south and southeast Asia and Oceania to Australia and New Zealand.
The family occurs mostly in southern to western Eurasia and surroundings, but it also ranges far into the Pacific, with some species in Africa.
Order: Passeriformes Family: Estrildidae The estrildid finches are small passerine birds of the Old World tropics and Australasia.
