List of birds of the Cayman Islands
This is a list of the bird species recorded in the Cayman Islands. The avifauna of the Cayman Islands include a total of 258 species, according to Bird Checklists of the World as of June 2018. Of them, 156 are rare or accidental and nine are introduced. One species (Grand Cayman thrush) was endemic to the islands but is now extinct, and one species (Jamaican oriole) has been extirpated. One additional accidental species has been added through eBird. BirdLife International has reclassified Grand Cayman's endemic Cuban bullfinch subspecies as a full species, the Grand Cayman bullfinch, but Clements has not yet accepted this. In addition, the islands hold most of the world population of vitelline warbler which otherwise occurs only on the Swan Islands in Honduras. There are 17 endemic subspecies belonging to 14 different species.
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, 2018 edition.
The following tags have been used to highlight several categories of occurrence.
- (A) Accidental - a species that rarely or accidentally occurs in the Cayman Islands
- (E) Endemic - a species endemic to the Cayman Islands
- (I) Introduced - a species introduced by humans either directly to Barbados or elsewhere in the New World

Most terns hunt fish by diving but some pick insects off the surface of fresh water. Terns are generally long-lived birds, with several species known to live in excess of 30 years. Skimmers are a small family of tropical tern-like birds. They have an elongated lower mandible which they use to feed by flying low over the water surface and skimming the water for small fish.

Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.
- Magnificent frigatebird, Fregata magnificens
Anhingas are often called "snake-birds" because of their long thin neck, which gives a snake-like appearance when they swim with their bodies submerged. The males have black and dark-brown plumage, an erectile crest on the nape, and a larger bill than the female. The females have much paler plumage especially on the neck and underparts. The darters have completely webbed feet and their legs are short and set far back on the body. Their plumage is somewhat permeable, like that of cormorants, and they spread their wings to dry after diving.
