Cuckoos are birds in the Cuculidae family, the sole taxon in the order Cuculiformes. The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals, and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae, respectively. The cuckoo order Cuculiformes is one of three that make up the Otidimorphae, the other two being the turacos and the bustards. The family Cuculidae contains 150 species, which are divided into 33 genera.
The cuckoo-roller or courol is the only bird in the family Leptosomidae, which was previously often placed in the order Coraciiformes but is now placed in its own order Leptosomiformes. The cuckoo-roller is at the root of a group that contains the Trogoniformes, Bucerotiformes, Piciformes, and Coraciiformes. Despite its name, the Cuckoo-roller does not share close evolutionary origins with cuckoos or rollers at all.
The Saint Helena hoopoe, also known as the Saint Helena giant hoopoe or giant hoopoe, is an extinct species of hoopoe known exclusively from an incomplete subfossil skeleton. Once endemic to the island of Saint Helena, it was last seen around 1550, likely driven to extinction by various aspects of human activity.
The Saint Helena crake is an extinct bird species from the island of Saint Helena in the South Atlantic Ocean, one of two flightless rails which survived there until the early 16th century.
The Saint Helena rail was a large flightless rail from Saint Helena. It became extinct in the early 16th century.
Saint Helena, Ascension Island and Tristan da Cunha, as well the other uninhabited islands nearby, are a haven for wildlife in the middle of the Atlantic Ocean. The islands are or were home to much endemic flora and fauna, especially invertebrates, and many endemic fish species are found in the reef ecosystems off the islands. The islands have been identified by BirdLife International as Important Bird Areas for both their endemic landbirds and breeding seabirds.
The Saint Helena plover, locally known as the wirebird due to its thin legs, is a small wader endemic to the island of Saint Helena in the mid-Atlantic. The bird is similar in appearance to Kittlitz's plover and the Madagascar plover, but a little larger and an absence of chamois coloring. It is the national bird of St Helena and has been depicted on the country's coins. Populations in general have been declining. Threats include predation by cats, the introduction of the common myna, deforestation, off-road vehicle use, the Saint Helena Airport and a projected windfarm. In 2016, the population had recovered to about 560 mature individuals, from a previous minimum of less than 200 in 2006; consequently, the species was downlisted to Vulnerable from its previous assessment of Critically Endangered.

The Pacific long-tailed cuckoo, also known as the long-tailed cuckoo, long-tailed koel, sparrow hawk, home owl, screecher, screamer or koekoeā in Māori, is a species of the Cuculidae bird family. It is a migratory bird that spends spring and summer in New Zealand, its only breeding place, and spends winter in the Pacific islands. It is a brood parasite, laying its eggs in the nests of other bird species and leaving them to raise its chicks.

The ruddy cuckoo-dove is a species of bird in the family Columbidae. It is a medium-sized, reddish brown cuckoo-dove, found in Brunei, Indonesia, and Malaysia. It is rated as a species of least concern on the International Union for Conservation of Nature Red List of Endangered Species.
Mackinlay's cuckoo-dove, also known as the spot-breasted cuckoo-dove, is a species of bird in the family Columbidae. It is found in Papua New Guinea, Solomon Islands, and Vanuatu. It is rated as a species of least concern on the International Union for Conservation of Nature Red List of Endangered Species.
The Timor cuckoo-dove is a species of bird in the family Columbidae. It is found in Timor, Wetar and the eastern Lesser Sundas. It was previously lumped together with the Tanimbar cuckoo-dove and the Flores Sea cuckoo-dove as the dusky or bar-necked cuckoo-dove.

The Philippine cuckoo-dove is a species of bird in the family Columbidae. It is found in the Philippines and Taiwan and is rated as a species of least concern on the International Union for Conservation of Nature Red List of Endangered Species.
The Oriental cuckoo or Horsfields cuckoo is a bird belonging to the genus Cuculus in the cuckoo family Cuculidae. It was formerly classified as a subspecies of the Himalayan cuckoo, with the name 'Oriental cuckoo' used for the combined species. Differences in voice and size suggest that it should be treated as a separate species. The binomial name Cuculus horsfieldi has often been used instead of Cuculus optatus, but is now usually considered to be a junior synonym.
