The red-bellied grackle (Hypopyrrhus pyrohypogaster) is a species of bird in the family Icteridae. Its genus, Hypopyrrhus, is monotypic. [2]
One of the grackles, it is endemic to Colombia where its natural habitat is subtropical or tropical moist montane forests. The species is threatened by habitat destruction and the International Union for Conservation of Nature considers it to be a "vulnerable species".
The male red-bellied grackle grows to about 30 cm (12 in) and the female about 27 cm (10.6 in). The sexes are similar in appearance being entirely black apart from a red belly and red under-tail coverts. The bill is conical in shape and the irises are white or yellow. When held in the hand it is possible to see that the feathers of the head, neck and throat have shiny, naked shafts and thick, narrow webs. [3]
The red-bellied grackle is endemic to Colombia where it is found in all three Andean ranges at altitudes of 800 to 2,400 m (2,600 to 7,900 ft) above sea level. Its natural habitat is tropical forest, but the trees are increasingly being felled for timber and to make way for agriculture, and little virgin forest remains within its range. However, it can tolerate some disturbance and can be seen at forest edges, in plantations, on cleared land, in scrub, over pasture and beside roads. [1]
Except during the breeding season, the red-bellied grackle is usually seen in small, noisy groups in the canopy. Sometimes these are mixed flocks with other grackles, and sometimes they may include Oropendolas . The grackles feed on fruit and insects, scrambling about among the branches and foliage, and sometimes clinging upside down. Breeding takes place between March and August. The nest is a cup-shaped structure in the fork of a tree, loosely composed of sticks and dead leaves. The eggs are greenish-grey, blotched and streaked with dark brown and lilac. [3] The giant cowbird (Molothrus oryzivorus) sometimes lays its eggs in the grackle's nest. [1]
H. pyrohypogaster was formerly classified as "endangered" by the International Union for Conservation of Nature but in 2012 the threat level was lowered to "vulnerable". This is on the basis that, although its forest habitat remains under pressure, it has been found at some new locations where it was not known before. The total population is now estimated to be in the range 2,500 to 9,999 individuals, occupying a land area of about 3,700 km2 (1,428.6 sq mi). The population is believed to be declining due to the continuing decline of the forest cover in the area and the fragmentation of its habitat. [1]
The maleo is a large megapode and the only member of the monotypic genus Macrocephalon. The maleo is endemic to Sulawesi and the nearby smaller island of Buton in Indonesia. It is found in the tropical lowland and hill forests, but nests in the open sandy areas, volcanic soils, or beaches that are heated by the sun or geothermal energy for incubation.
The Satanic nightjar, also Heinrich's nightjar, satanic eared-nightjar, Sulawesi eared-nightjar or diabolical nightjar is a mid-sized, spotted, dark brown nightjar endemic to the Indonesian island of Sulawesi. The species was discovered in 1931 by Gerd Heinrich, a German natural historian who collected a single female holotype from Mount Klabat on the Minahasa peninsula of Northern Sulawesi. In the following decades, there were a few unconfirmed reports of sightings and calls of the bird, but it did not officially resurface until 1996 when David Bishop and Jared Diamond positively identified it in Lore Lindu National Park by its sound. Making the visible rediscovery available for multiple people in the tour group including poet and writer Jan Zwaaneveld. This increased the bird's estimated range by 750 km (470 mi). It has since been observed and described in the literature multiple times.
The orange-collared manakin is a passerine bird in the manakin family. It is an endemic resident breeder in Costa Rica and western Panama, where it is found in forests, secondary growth and plantations. It is a small, plump bird about 10 centimetres (4 in) long. Males have a black crown, mid back, wings and tail and an olive-green rump. The rest of the head, neck, breast and upper back are orange, and the belly is yellow. Females are olive-green with yellow underparts and resemble female white-collared manakins. At breeding time, males are involved in lekking behaviour on the forest floor. This is a fairly common species with a somewhat restricted range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The Sula megapode or Sula scrubfowl is a species of bird in the family Megapodiidae. It is found only in the Banggai and Sula Islands between Sulawesi and the Maluku Islands in Indonesia, where its habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, and subtropical or tropical moist shrubland. It is threatened by habitat destruction.
The black-bellied cuckoo or black-bellied squirrel cuckoo is a bird of the family Cuculidae found in the Amazon region. Even though this species has a wide distribution, little is known about its ecology and natural history. The word melanogaster means "black belly"; it has Greek roots, melas meaning "black" and gaster meaning "belly".
The rufous-fronted parakeet is a species of parrot in the family Psittacidae. Endemic to Colombia, its natural habitats are high-altitude shrubland, high-altitude grassland and arable land. It is threatened by habitat destruction and is classified as "vulnerable" by the International Union for Conservation of Nature.
The golden-plumed parakeet is a Neotropical parrot species within the family Psittacidae, belonging to the monotypic genus Leptosittaca. This somewhat Aratinga-like species is found in humid temperate highland forests, especially with Podocarpus, on the east Andean slope in Colombia, Ecuador, and Peru. It is generally local and uncommon. It is threatened by habitat loss. Clearing of high-altitude forests for agricultural reasons have greatly impacted the loss of habitat for this parakeet species. Further reduction of such habitats will continue to diminish the number of golden-plumed parakeets left in South America. It is the only known parakeet species that can detect ultraviolet radiation.
The Santa Marta parakeet is an Endangered species of bird in subfamily Arinae of the family Psittacidae, the African and New World parrots. It is endemic to Colombia.
The grey-headed imperial pigeon is a species of bird in the family Columbidae. It is endemic to Sulawesi in Indonesia. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
The chestnut-bellied flowerpiercer is a species of bird in the family Thraupidae. It is endemic to Colombia.
The Martinique oriole is a species of bird in the family Icteridae. It is endemic to Martinique, French West Indies. Martinique is a part of the Lesser Antilles, and is located in the Eastern Caribbean.
The velvet-fronted grackle is a species of bird in the family Icteridae, monotypic within the genus Lampropsar. It is found in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela where its natural habitats are subtropical or tropical swamps and heavily degraded former forest.
The rufous-tailed stipplethroat or rufous-tailed antwren is a species of insectivorous bird in the antbird family Thamnophilidae. It was formerly placed in the genus Myrmotherula. It is found in Brazil, Colombia, Ecuador, and Peru. Its natural habitat is subtropical or tropical moist lowland forests.
The tanager finch is a songbird species. In spite of its common name, it is neither a tanager nor a finch, but a New World bunting, having been moved to that family after variously being placed in either the Emberizidae or the true tanager family Thraupidae. It is the only species in the monotypic genus Oreothraupis. It is found in Colombia and Ecuador, where its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
The Baudó oropendola is a species of bird in the family Icteridae. It is endemic to Colombia. Its natural habitat is subtropical or tropical moist lowland forests, which are threatened by destruction. As it is only known from a small number of locations, its conservation status has been assessed as "endangered" by the IUCN.
The black oropendola is a species of bird in the family Icteridae. It is found in Colombia and Panama. Its natural habitat is subtropical or tropical moist lowland forests.
The white-breasted thrasher, also known as goj blan in Creole, is a species of bird in the family Mimidae. Semper and Sclater (1872) describe the white-breasted thrasher as an "inquisitive and noisy bird" that would often "keep up a constant warning chatter, and throw itself about in all sorts of contortions" when being disturbed. It is endemic to Martinique and Saint Lucia, found only on these two islands of the Lesser Antilles. This resident species is easy to find within its range; however, it is classified as endangered by the IUCN Red List of Threatened Species mainly due to its restricted habitat.
The flame-faced tanager is a species of bird in the tanager family Thraupidae. It is endemic to South America and is found in the eastern Andes of Colombia, Ecuador, Peru and Venezuela. Its natural habitat is subtropical or tropical moist montane forests. It is a distinctive-looking species with black and opalescent green upperparts, opalescent green and buff underparts, and a deep red and yellow face. The subspecies lunigera lacks the deep red on the face, which is replaced with orangish-red.
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 Hispaniolan trogon is a species of bird in the family Trogonidae. It is endemic to Hispaniola in the Caribbean. It is one of the only two trogon species found in the Caribbean. It is the national bird of Haiti.
