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.
Icterids or New World blackbirds make up a family, the Icteridae, of small to medium-sized, often colorful, New World passerine birds. The family contains 108 species and is divided into 30 genera. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. The name, meaning "jaundiced ones" comes from the Ancient Greek ikteros via the Latin ictericus. This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, grackles, cowbirds, oropendolas, and caciques.
The black-billed cuckoo is a New World species in the Cuculidae (cuckoo) family. The scientific name is from Ancient Greek. The genus name, kokkuzo, means to call like a common cuckoo, and erythropthalmus is from eruthros, "red" and ophthalmos, "eye".
The violet-green swallow is a small North American passerine bird in the swallow family. These aerial insectivores are distributed along the west coast from Alaska to Mexico, extending as far east as Montana and Texas. With an appearance very similar to the tree swallow, these individuals can be identified by the white rump side-patches that appear to separate their green back and purple tail. Violet-green swallows are secondary cavity nesters, found in a number of habitats including deciduous and coniferous forest. In addition to nesting in tree holes within these habitats, they are also widely observed nesting in the cracks of large cliffs.
The anis are the three species of birds in the genus Crotophaga of the cuckoo family. They are essentially tropical New World birds, although the range of two species just reaches the United States.
The greater ani is a bird in the cuckoo family. It is sometimes referred to as the black cuckoo. It is found through tropical South America south to northern Argentina.
The smooth-billed ani is a bird in the cuckoo family. It is a resident breeding species from southern Florida, the Caribbean, parts of Central America, south to western Ecuador, Brazil, northern Argentina and southern Chile. It was introduced to Galápagos around the 1960s and is potentially impacting native and endemic species across the archipelago.
The groove-billed ani is a tropical bird in the cuckoo family with a long tail and a large, curved beak. It is a resident species throughout most of its range, from southern Texas, central Mexico and The Bahamas, through Central America, to northern Colombia and Venezuela, and coastal Ecuador and Peru. It only retreats from the northern limits of its range in Texas and northern Mexico during winter.
The guira cuckoo is a gregarious bird found widely in open and semi-open habitats of northeastern, eastern and southern Brazil, Uruguay, Paraguay, Bolivia, and northeastern Argentina. It is the only species placed in the genus Guira.
The yellow-rumped thornbill is a species of passerine bird from the genus Acanthiza. The genus was once placed in the family Pardalotidae but that family was split and it is now in the family Acanthizidae. There are four subspecies of yellow-rumped thornbill. It is a small, brownish bird with a distinctive yellow rump and thin dark bill. It inhabits savannah, scrub and forests across most of Australia and eats insects. The species engages in cooperative breeding.
The Malagasy coucal or Madagascar coucal is a species of cuckoo in the family Cuculidae. It is found in Madagascar and in the Seychelles, where it occurs on Aldabra and was formerly present on Assumption Island and Cosmoledo. Its natural habitats are dense vegetation in subtropical or tropical moist lowland forests, mangrove forests, rough grassland, marshes and reedbeds.
Horsfield's bronze cuckoo is a small cuckoo in the family Cuculidae. Its size averages 22g and is distinguished by its green and bronze iridescent colouring on its back and incomplete brown barring from neck to tail. Horsfield's bronze cuckoo can be destiguished from other bronze cuckoos by its white eyebrow and brown eye stripe. The Horsfield's bronze cuckoo is common throughout Australia preferring the drier open woodlands away from forested areas.
The shining bronze cuckoo is a species of cuckoo in the family Cuculidae, found in Australia, Indonesia, New Caledonia, New Zealand, Papua New Guinea, Solomon Islands, and Vanuatu. It was previously also known as Chalcites lucidus.
The dark-billed cuckoo is a species of bird in the tribe Phaenicophaeini, subfamily Cuculinae of the cuckoo family Cuculidae. It is regularly found in every mainland South American country except Chile plus the Galápagos Islands. It has also occurred as a vagrant in Chile and several other countries and islands.
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 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 channel-billed cuckoo is a species of cuckoo in the family Cuculidae. It is monotypic within the genus Scythrops. The species is the largest brood parasite in the world, and the largest cuckoo.
The nelicourvi weaver is a species of bird in the family Ploceidae. It is endemic to Madagascar. Together with its closest relative, the sakalava weaver, it is sometimes placed in a separate genus Nelicurvius. A slender, sparrow-like bird, it is 15 cm (5.9 in) long and weighing 20–28 g (0.71–0.99 oz). Breeding males have a black bill and head, brown eyes, yellow collar, grey belly, chestnut-brown lower tail coverts, olive back, and blackish flight feathers edged greenish. Non-breeding males have mottled grey and green heads. In the breeding female the front of the head is yellow and the back olive green, with a broad yellow eyebrow. It builds solitary, roofed, retort-shaped nests, hanging by a rope from a branch, vine or bamboo stem, in an open space. It primarily feeds on insects, looking on its own or in very small groups, often together with long-billed bernieria. Its natural habitat is subtropical or tropical moist lowland and mountain forests. The conservation status of Nelicourvi weaver is least concern according to the IUCN Red List.
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.
Within the insect order Hymenoptera, the Halictinae are the largest, most diverse, and most recently diverged of the four halictid subfamilies. They comprise over 2400 bee species belonging to the five taxonomic tribes Augochlorini, Thrinchostomini, Caenohalictini, Sphecodini, and Halictini, which some entomologists alternatively organize into the two tribes Augochlorini and Halictini.
