Answer the following question: Information:  - Venezuela, officially the Bolivarian Republic of Venezuela, is a federal republic located on the northern coast of South America. It is bordered by Colombia on the west, Brazil on the south, Guyana on the east, and the islands of Trinidad and Tobago to the north-east. Venezuela's territory covers around with an estimated population . Venezuela is considered a state with extremely high biodiversity (currently ranks 7th in the world's list of nations with the most number of species), with habitats ranging from the Andes Mountains in the west to the Amazon Basin rain-forest in the south, via extensive "llanos" plains and Caribbean coast in the center and the Orinoco River Delta in the east.  - A passerine is any bird of the order Passeriformes, which includes more than half of all bird species. A notable feature of passerines compared to other orders of Aves is the arrangement of their toes, three pointing forward and one back, which facilitates perching. Sometimes known as perching birds or, less accurately, as songbirds, the passerines form one of the most diverse terrestrial vertebrate orders, with over 5,000 identified species. It has roughly twice as many species as the largest of the mammal orders, the Rodentia. It contains more than 110 families, the second-most of any order of tetrapods (after Squamata, the scaled reptiles). The passerines contain several groups of brood parasites such as the viduas, cuckoo-finches, and the cowbirds. Most passerines are omnivorous, while the shrikes are carnivorous.  - Manacus is a genus of passerine birds in the manakin family which are found in the forests of tropical mainland Central and South America , and on Trinidad and Tobago . There are four species . White - collared manakin , Manacus candei Orange - collared manakin , Manacus aurantiacus Golden - collared manakin , Manacus vitellinus White - bearded manakin , Manacus manacus The `` Almirante manakin '' ( Manacus x cerritus ) are stereotyped hybrids between the white - collared and the golden - collared species , found in Bocas del Toro Province , Panama ( Brumfield et al. , 2001 ; McDonald et al. , 2001 ) . These are small , compact , short - tailed birds with a heavy hooked bill and orange legs . The males have brightly coloured plumage and long puffed throat feathers , whereas the females are the typical manakin dull olive hue . The females lay two eggs in a shallow cup nest in a tree . Nest - building , incubation for 18 -- 21 days , and care of the young are undertaken by the female alone , since manakins do not form stable pairs . Manacus manakins feed low in the trees on fruit and some insects , both plucked from the foliage in flight . Like some other manakin species , this genus has spectacular courtship rituals , in which the males give communal displays in a specially prepared lek . The males jump with their throat feathers erected to form a beard , and give whistles together with the characteristic loud snaps ( like a breaking twig ) and various buzzing , rustling and whiffling noises made with the wings . The males of three very closely related species , the white - collared manakin of the Caribbean slopes of Central America , and its Pacific counterparts , the orange - collared and golden - collared manakins , have heavily modified wings with the five outer primaries very narrow for their outer half , and the inner primaries thickened and bowed .  - Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection.  - Brood parasites are organisms that rely on others to raise their young. The strategy appears among birds, insects and some fish. The brood parasite manipulates a host, either of the same or of another species, to raise its young as if it were its own.  - A continent is one of several very large landmasses on Earth. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in size to smallest, they are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. In geology, areas of continental crust include regions covered with water.  - Rodents (from Latin "rodere", "to gnaw") are mammals of the order Rodentia, which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents; they are found in vast numbers on all continents except Antarctica. They are the most diversified mammalian order and live in a variety of terrestrial habitats, including human-made environments.  - The cuckoos are a family of birds, Cuculidae, 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.  - Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones). Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 64,000 species described. Vertebrates include the jawless fish and the jawed vertebrates, which include the cartilaginous fish (sharks and rays) and the bony fish.   - The cuckoo-finch ("Anomalospiza imberbis"), 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. The eggs are laid in the nests of other birds.  - Tobago is an autonomous island within the Republic of Trinidad and Tobago. It is located northeast of the mainland of Trinidad and southeast of Grenada. The island lies outside the hurricane belt. According to the earliest English-language source cited in the "Oxford English Dictionary", Tobago bore a name that has become the English word "tobacco." The national bird of Tobago is the cocrico.  - Tobacco is a product prepared from the leaves of the tobacco plant by curing them. The plant is part of the genus "Nicotiana" and of the Solanaceae (nightshade) family. While more than 70 species of tobacco are known, the chief commercial crop is "N. tabacum". The more potent variant "N. rustica" is also used around the world.  - Shrikes are carnivorous passerine birds of the family Laniidae. The family is composed of thirty-one species in four genera. They are fairly closely related to the bush-shrike family Malaconotidae.  - Mammals are any vertebrates within the class Mammalia (from Latin "mamma" "breast"), a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. The sister group of mammals may be the extinct "Haldanodon." The mammals represent the only living Synapsida, which together with the Sauropsida form the Amniota clade. The mammals consist of the Yinotheria including monotrema and the Theriiformes including the theria.  - Cowbirds are birds belonging to the genus Molothrus in the family Icteridae. They are brood parasitic New World birds which are unrelated to the Old World cuckoos, one of which, the common cuckoo, is the most famous brood parasitic bird.  - Birds (Aves), also known as avian dinosaurs, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds.  - The West Indies or Caribbean Basin is a region of the North Atlantic Ocean in the Caribbean, that includes the island nations and surrounding waters of three major archipelagoes: the Greater Antilles, the Lesser Antilles and the Lucayan Archipelago. The term is synonymous with the term "Caribbean Basin". The region is known as the area running from Florida westward along the Gulf coast, then south along the Mexican coast through Central America and then eastward across the northern coast of South America. Bermuda is also included within the region even though it is in the west-central Atlantic, due to its common cultural history created by European colonization of the region, and in most of the region by the presence of a significant group of African descent.  - Passer is a genus of sparrows, also known as the true sparrows. The genus includes the house sparrow and the Eurasian tree sparrow, some of the most common birds in the world. They are small birds with thick bills for eating seeds, and are mostly coloured grey or brown. Native to the Old World, some species have been introduced throughout the world.  - The manakins are a clade (Pipridae) of small suboscine passerine birds. The group contains some 60 species distributed through the American tropics. The name is from Middle Dutch "mannekijn" "little man" (also the source of the different bird name "mannikin").  - Trinidad (Spanish: "Trinity") is the larger and more populous of the two major islands and numerous landforms which make up the island nation of Trinidad and Tobago. The island lies off the northeastern coast of Venezuela and sits on the continental shelf of South America. Though geographically part of the South American continent, from a socio-economic standpoint it is often referred to as the southernmost island in the Caribbean. With an area of , it is also the sixth largest in the West Indies.  - A songbird is a bird belonging to the clade Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as a scientific or vernacular name is Oscines, from Latin "oscen", "a songbird". This group contains some 4,000 species found all over the world, in which the vocal organ typically is developed in such a way as to produce a diverse and elaborate bird song.  - Southern Cone is a geographic region composed of the southernmost areas of South America, south of and around the Tropic of Capricorn. Traditionally, it covers Argentina, Chile and Uruguay, bounded on the west by the Pacific Ocean, and south to the junction between the Pacific and Atlantic Oceans, which is the closest continental area of Antarctica (1000 km). In terms of social and political geography, the Southern Cone comprises Argentina, Chile, Uruguay, Southern Brazil and sometimes Paraguay.  - South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil).  - The order Squamata, or the scaled reptiles, are the largest recent order of reptiles, comprising all lizards and snakes. With over 10,000 species, it is also the second-largest order of extant vertebrates, after the perciform fish, and roughly equal in number to the Saurischia (one of the 2 major groups of dinosaurs). Members of the order are distinguished by their skins, which bear horny scales or shields. They also possess movable quadrate bones, making it possible to move the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. They are the most variably sized order of reptiles, ranging from the dwarf gecko ("Sphaerodactylus ariasae") to the green anaconda ("Eunectes murinus") and the now-extinct mosasaurs, which reached lengths of .
