Manacus
''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. The genus ''Manacus'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the white-bearded manakin (''Manacus manacus'') as the type species. The name ''manacus'' is from the Dutch ''manneken'' "pretty little thing". The genus contains four species: 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.

White-collared Manakin
The white-collared manakin (''Manacus candei'') is a passerine bird in the manakin family. It is a resident breeder in the tropical New World from southeastern Mexico to Costa Rica and the extreme west of Panama. It typically inhabits thickets at the edges of moist forest, tall secondary growth and old cacao plantations. It is a small, plump bird about long. Males have a black crown, mid-back band, wings and tail, an olive-green rump and yellow belly. Females and juveniles are olive-green with yellow bellies and resemble female orange-collared manakins. At breeding time, males are involved in lekking behaviour on the forest floor during which they puff out their neck feathers. This is a fairly common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".

Manakin
The manakins are a Family (biology), family, Pipridae, of small Tyranni, suboscine passerine birds. The group contains some 54 species distributed through the American tropics. The name is from Middle Dutch ''mannekijn'' "little man" (also the source of the different bird name ''Munia, mannikin''). Description Manakins range in size from and in weight from . Species in the genus ''Tyranneutes'' are the smallest manakins, those in the genus ''Antilophia'' are believed to be the largest (since the genus ''Schiffornis'' are no longer considered manakins). They are compact stubby birds with short tails, broad and rounded wings, and big heads. The beak, bill is short and has a wide gap. Females and first-year males have dull green plumage; most species are sexual dimorphism, sexually dichromatic in their plumage, the males being mostly black with striking colours in patches, and in some species having long, decorative tail or crown feathers or erectile throat feathers.

Golden-collared Manakin
The golden-collared manakin (''Manacus vitellinus'') is a species of bird in the family Pipridae. It is found in Colombia and Panama. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest. Reproduction Male golden-collared manakins perform an acrobatic display and use vocalizations to court females. Males emit a specific ''chee-poo'' sound during courtship. Studies have examined whether the call of golden-collared manakins is physiologically controlled by peripheral androgen receptors. When androgen receptors outside of the central nervous system were inhibited, this resulted in an increase in the duration of the ''chee'' note and a decrease in the frequency of the ''poo'' note. These results show that the activation of peripheral androgen receptors is important for creating a normal sexual call in the golden-collared manakin.

Orange-collared Manakin
The orange-collared manakin (''Manacus aurantiacus'') 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 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". Description The orange-collared manakin is, like its relatives, a compact short-tailed bird with a heavy hooked bill, orange legs and brightly coloured male plumage. It is typically 10 cm long and weig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lek (animal Behavior)
A lek is an aggregation of male animals gathered to engage in competitive displays and courtship rituals, known as lekking, to entice visiting females which are surveying prospective partners with which to mate. A lek can also indicate an available plot of space able to be utilized by displaying males to defend their own share of territory for the breeding season. A lekking species is characterised by male displays, strong female mate choice, and the conferring of indirect benefits to males and reduced costs to females. Although most prevalent among birds such as black grouse, lekking is also found in a wide range of vertebrates including some bony fish, amphibians, reptiles, and mammals, and arthropods including crustaceans and insects. A classical lek consists of male territories in visual and auditory range of each other. An exploded lek, as seen in the kakapo (the owl parrot), has more widely separated territories, but still in auditory range. Lekking is associated w ...

Pacific
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .
