Crotophagidae
The Crotophaginae are a small subfamily, within the cuckoo family Cuculidae, of four gregarious bird species occurring in the Americas. They were previously classified as a family Crotophagidae. The subfamily is notable for the development of cooperative breeding where several females lay eggs in a communal nest. It contains the three anis and the guira cuckoo. Among the anis, there is considerable variation in nesting habits. One species, The greater ani (''Crotophaga major'') lays 2 or 3 eggs, while the groove-billed ani (''C. sulcirostris'') lays seven. However the smooth-billed ani (''C. ani'') will share one nest between several females, with up to 29 eggs in one nest. Incubation takes 15 days for this species. Systematics Four species make up the subfamily, namely the guira cuckoo (''Guira guira'') and the three members of the genus ''Crotophaga'' known as anis.

Cuculidae
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 cuckoos are generally medium-sized slender birds. Most species live in trees, though a sizeable minority are ground-dwelling. The family has a cosmopolitan distribution; the majority of species are tropical. Some species are migratory. The cuckoos feed on insects, insect larvae and a variety of other animals, as well as fruit. Some species are brood parasites, laying their eggs in the nests of other species and giving rise to the metaphor ''cuckoo's egg'', ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Subfamilies
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groove-billed Ani
The groove-billed ani (''Crotophaga sulcirostris'') 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. Taxonomy The groove-billed ani was formally described by the English naturalist William John Swainson from a specimen collected in Temascaltepec, Mexico. It still bears its original binomial name of ''Crotophaga sulcirostris''. The specific epithet combines the Latin meaning "furrow" with ''-'' meaning "-billed". The species is monotypic: no subspecies are recognised. Description The groove-billed ani is about long, and weighs . Wingspan ranges 41-46 cm (16-18 in). It is completely black, with a very long tail almost as long as its body. It has a huge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smooth-billed Ani
The smooth-billed ani (''Crotophaga 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. Taxonomy The smooth-billed ani was described and illustrated in 1648 by the German naturalist Georg Marcgrave in his ''Historia Naturalis Brasiliae''. He used the name "Ani" but did not explain the origin of the word. It probably comes from the word ''Anim'' in the Tupi language which means "social bird". In 1756 the Irish physician Patrick Browne used the name ''Crotophaga'' for the species in his ''The Civil and Natural History of Jamaica''. Browne's name combines the Ancient Greek ''krotōn'' meaning "tick" with ''-phagos'' meaning "-eating". Browne wrote that the smooth-billed anis "live chiefly upon ticks a ...

Crotophaga
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.Payne, R.B. (2005). ''The Cuckoos''. Oxford University Press. Unlike some cuckoos, the anis are not brood parasites, but nest communally, the cup nest being built by several pairs from 2–6 m high in a tree. A number of females lay their eggs in the nest and then share incubation and feeding. The anis are large black birds with a long tail and a deep ridged black bill. Their flight is weak and wobbly, but they run well, and usually feed on the ground. These are very gregarious species, always found in noisy groups. Anis feed on termites, large insects, and even lizards and frogs. The claim that they will remove ticks and other parasites from grazing animals has been disputed; while there is no doubt that anis follow grazing animals to catch disturbed insects and will occasi ...
