Guira guira (Gmelin, JF, 1788) | |
The guira cuckoo (Guira guira) 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 guira cuckoo was described and illustrated in 1648 by the German naturalist Georg Marcgrave in his Historia Naturalis Brasiliae. He used the name "Guira angatara". [2] The word Güirá means "bird" in the Guarani language. [3] Later ornithologists based their descriptions on Marcgrave's account: Francis Willughby in 1678, [4] John Ray in 1713, [5] Mathurin Jacques Brisson in 1760, [6] and Georges-Louis Leclerc, Comte de Buffon in 1779. [7] When the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae in 1788 he included the guira cuckoo. He placed it with all the other cuckoos in the genus Cuculus and coined the binomial name Cuculus guira. [8] The guira cuckoo is now the only species placed in the genus Guira that was introduced in 1830 by the French naturalist René Lesson. [9] [10] The species in monotypic: no subspecies are recognised. [10] It is most closely related to the anis in the genus Crotophaga. [11]
The guira cuckoo has a total length of approximately 34 cm (13 in) and weighs 140 g (4.9 oz). [12] The sexes are very similar in appearance, except that the female is slightly larger than the male. Juveniles appear quite similar to adults.
The species has dark brown upperparts streaked with white, and whitish-buff throat, breast, underparts and rump. The tail is relatively long and broad, dark brown in color with a white-tip, and the legs are dark gray. The eyes and beak are yellow to orange, with a thin ring of featherless yellow skin around the eye (this commonly fades in captivity). There is a prominent orange-rufous crest.
The bird's call is unmistakable for being long and shrill, something between a long whistle and a wailing. Like other members of the subfamily Crotophaginae, the guira cuckoo gives off a strong, pungent odour. [13]
The guira cuckoo is a bird of open habitats such as pastures and wetlands, and its range has expanded significantly due to deforestation. Within its distribution, it is commonly seen in suburban parks and gardens. Like the related squirrel cuckoo, the guira cuckoo is not a particularly adept flier, and usually flies only for short distances. It is often seen gliding or hopping from one perch to another while vocalizating loudly.
Although it is primarily an arboreal bird, it is often seen foraging on the ground, sometimes alone but often in flocks of up to 18 individuals. It is sometimes seen with other birds whose behaviour is similar, such as the smooth-billed ani. Unlike many of the Old World cuckoos, the guira cuckoo does not practice brood parasitism or kleptoparasitism.
The guira cuckoo is an opportunistic predator, gathering small prey items on the ground or searching for them among branches. It feeds on worms, insects and other arthropods, tadpoles and frogs, eggs, small birds (especially nestlings) and small mammals such as mice. [14] It also has been observed feeding on lizards. [15]
The nest is built on a tree fork 2 to 5 m (6.6 to 16.4 ft) from the ground. The eggs (from 5 to 7) are dark green and covered with a chalky layer. They are incubated either in individual or community nests; in the latter one can find up to 20 eggs. Under community nests there are many broken eggs. The competition between young being great, mortality is significant.
The Senegal coucal is a member of the cuckoo order of birds, the Cuculiformes, which also includes the roadrunners, the anis, and the hoatzin. It is a medium-sized member of its genus and is found in lightly-wooded country and savannah in central and southern Africa.
The horned screamer is a member of a small family of birds, the Anhimidae, which occurs in wetlands of tropical South America. There are three screamer species, the other two being the southern screamer and the northern screamer in the genus Chauna. They are related to the ducks, geese and swans, which are in the family Anatidae, but have bills looking more like those of game birds.
The great black hawk is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures.
The great kiskadee, called bem-te-vi in Brazil, pitogue in Paraguay, and benteveo or bichofeo in Argentina, is a passerine bird in the tyrant flycatcher family Tyrannidae. It is the only member of the genus Pitangus.
The great tinamou is a species of tinamou ground bird native to Central and South America. There are several subspecies, mostly differentiated by their coloration.
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 mangrove cuckoo is a species of cuckoo that is native to the Neotropics.
Cuculus is a genus of cuckoos which has representatives in most of the Old World, although the greatest diversity is in tropical southern and southeastern Asia.
The golden parakeet or golden conure, or the Queen of Bavaria conure is a medium-sized golden-yellow Neotropical parrot native to the Amazon Basin of interior northern Brazil. It is the only species placed in the genus Guaruba.
The red-legged seriema, also known as the crested cariama and crested seriema, is a mostly predatory terrestrial bird in the seriema family (Cariamidae), included in the Gruiformes in the old paraphyletic circumscription but recently placed in a distinct order: Cariamiformes.
The jandaya parakeet or jenday conure is a small Neotropical parrot with green wings and tail, reddish-orange body, yellow head and neck, orange cheeks, and black bill, native to wooded habitats in northeastern Brazil. It is a member of the Aratinga solstitialis complex of parakeets very closely related to, and possibly subspecies of the sun parakeet.
The spotted puffbird is a species of puffbird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.
The caatinga puffbird is a species of bird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is endemic to Brazil.
The lesser coucal is a species of cuckoo in the family Cuculidae. It has a wide distribution range that overlaps with several other similar species. The habitat in which it is found is often marshy land with grass and tree cover. It is distinguished by its smaller size, less prominent bill, pale shaft streaks on the feathers of the head and back. It has a much longer claw on its hind toe and a distinct call. It is also among the few coucals that show season plumage differences but like in other coucals, the sexes cannot be distinguished in the field.
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 Asian emerald cuckoo is a species of cuckoo in the family Cuculidae. It is found in Bangladesh, Bhutan, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Sri Lanka, Thailand, and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forest.
The guira tanager is a species of bird in the family Thraupidae.
The campo troupial or campo oriole is a species of bird in the family Icteridae that is found in northeastern Brazil. At one time thought to be conspecific with the Venezuelan troupial and orange-backed troupial, it is now accepted as a separate species. It is a fairly common bird and the International Union for Conservation of Nature has rated it as a "least-concern species".
