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, common cuckoo, European cuckoo or Eurasian cuckoo is a member of the cuckoo order of birds, Cuculiformes, which includes the roadrunners, the anis and the coucals.
The water pipit is a small passerine bird which breeds in the mountains of Southern Europe and the Palearctic eastwards to China. It is a short-distance migrant; many birds move to lower altitudes or wet open lowlands in winter.
The shiny cowbird is a passerine bird in the New World family Icteridae. It breeds in most of South America except for dense forests and areas of high altitude such as mountains. Since 1900 the shiny cowbird's range has shifted northward, and it was recorded in the Caribbean islands as well as the United States, where it is found breeding in southern Florida. It is a bird associated with open habitats, including disturbed land from agriculture and deforestation.
The striped cuckoo is a near-passerine bird, the only member of the genus Tapera. This resident cuckoo is found from Mexico and Trinidad south to Bolivia and Argentina and Colombia.
Euler's flycatcher is a small passerine bird in the tyrant flycatcher family. It breeds in South America east of the Andes from Colombia and Venezuela south to Bolivia and Argentina, and on the islands of Trinidad and formerly also Grenada. This species is named for the Swiss ornithologist Carl Euler.
Levaillant's cuckoo is a cuckoo which is a resident breeding species in Africa south of the Sahara. It is found in bushy habitats. It is a brood parasite, using the nests of bulbuls and babblers. It was named in honour of the French explorer, collector and ornithologist, François Le Vaillant.
Cuculus saturatus, better well known as the Himalayan cuckoo or Oriental cuckoo, is a brooding parasitic bird that is part of the Cuculidae family. The species breeds from the Himalayas eastward to southern China and Taiwan. It migrates to southeast Asia and the Greater Sunda Islands for the winter.
The violet cuckoo is a species of cuckoo in the family Cuculidae.
The black cuckoo is a species of cuckoo in the family Cuculidae. The species is distributed widely across sub-Saharan Africa. There are two subspecies. This cuckoo has a very wide range and is quite common so it is classified as a least-concern species by the International Union for Conservation of Nature.
The African cuckoo or African grey cuckoo is a species of cuckoo in the family Cuculidae. It is found in Sub-Saharan Africa where it migrates within the continent, generally arriving and breeding in any one locality during the rainy season. A fairly common bird, the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The pallid cuckoo is a species of cuckoo in the family Cuculidae. It is found in Australia, with some migration to the islands of Timor and Papua New Guinea. It is between 28 and 33 cm in size, with distinctive markings such as a dark bill, a dark eye with a gold eye-ring and olive grey feet which differentiate it from other cuckoos. The pallid cuckoo is similar in appearance to the oriental cuckoo, with barred immature pallid cuckoos being often mistaken for oriental cuckoos.
The red-chested cuckoo is a species of cuckoo in the family Cuculidae. It is a medium-sized bird found in Africa, south of the Sahara. In Afrikaans, it is known as "Piet-my-vrou", after its call.
The pheasant cuckoo is a species of neotropical cuckoo in the subfamily Neomorphinae of the family Cuculidae. It is native to Central and South America where it occurs in lowland tropical forest.
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 cuckoo-finch, also known as the parasitic weaver or cuckoo weaver, is a small passerine bird now placed in the family Viduidae with the indigobirds and whydahs. It occurs in grassland in Africa south of the Sahara. The male is mainly yellow and green while the female is buff with dark streaks. They lay their eggs in the nests of other birds.
The white-tipped quetzal is a species of bird in the family Trogonidae found in Venezuela, Colombia, and Guyana. Two subspecies have been described. Pharomachrus fulgidus fulgidus is found in the mountains of northern Venezuela and Pharomachrus fulgidus festatus ranges through the Santa Marta mountains of northeast Colombia. Quetzals are iridescent and colourful birds found in forests, woodlands and humid highlands. The white-tipped quetzal has been a limited subject of research. Pharomachrus nests have been studied to analyse the effects of rainfall on breeding, however conclusions are based on single observations. On the IUCN Red list of threatened species, the white-tipped quetzal is listed as a species of least concern.
The pavonine quetzal is a species of bird in the family Trogonidae, the trogons. It is also known at the peacock trogon, red-billed train bearer, or viuda pico rojo in Spanish. The pavonine quetzal lives in the Neotropics, more specifically in the northern region of the Amazon basin, spreading from Colombia to Bolivia. The most notable characteristics helpful in identifying this bird are its plumage, red beak, and its distribution - it is the only quetzal occupying the lowland rainforest east of the Andes.
The spot-bellied bobwhite is a ground-dwelling bird in the New World quail family. It is sometimes considered to be conspecific with the crested bobwhite, Colinus cristatus. As the latter species expands north into Costa Rica, it is likely that the two species will overlap in range in the future, but the Costa Rican subspecies of the spot-bellied is the least similar to the crested.
Egg tossing or egg destruction is a behavior observed in some species of birds where one individual removes an egg from the communal nest. This is related to infanticide, where parents kill their own or other's offspring. Egg tossing is observed in avian species, most commonly females, who are involved with cooperative breeding or brood parasitism. Among colonial non-co-nesting birds, egg-tossing is observed to be performed by an individual of the same species, and, in the case of brood parasites, this behavior is done by either the same or different species. The behavior of egg tossing offers its advantages and disadvantages to both the actor and recipient.
