Pauxi
The genus ''Pauxi'' consists of the three species of helmeted curassows, terrestrial black fowl with ornamental casque on their heads. All are found in South America. This genus contains 3 species As indicated by analysis of mtDNA, mt and nDNA DNA sequence, sequences and calibrated with geological data, this genus' ancestors probably diverged from those of ''Mitu (bird), Mitu'', their closest living relatives, in the Tortonian (early Late Miocene), some 8–7.4 mya (unit), mya. How the present distribution in 4 small areas quite distant from each other came to be is not known. Given that helmeted curassows are birds of the foothills and uplands, it might be that the ancestral ''Pauxi'' population became fragmented by the uplift of the Andes, which in their area of distribution took place during the Late Miocene, around the ''Pauxi''-''Mitu'' divergence and some time after.(Pereira & Baker 2002, Pereira ''et al.'' 2002). Pereira & Baker (2002) reported an interesting find: in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sira Curassow
The Sira curassow (''Pauxi koepckeae'') is a species of bird in the family Cracidae. It is found in the El Sira Communal Reserve, Cerros del Sira in central Peru. Its natural habitat is tropical, moist, montane cloud forest. It was first discovered in 1969, when a male and female were recovered (unfortunately the female specimen was accidentally eaten), and was not recorded by scientists again until 2000 and 2003, when local Asháninka people were shown pictures of the birds and respectively 1 and 14 people recalled having seen or hunted them in the past few years. The name 'Sira curassow' was proposed as a new English common name in 2011 by Gastañaga ''et al.'' to replace the previous 'horned curassow', in 2012 this proposal was adopted by most of her colleagues. In the Asháninka language of the area the bird is known as ''quiyuri'' according to Weske & Terborgh [1971], ''piyori'' according to the report 'Nombres Asháninka de las Aves en la Cordillera el Sira' by González [1 ...
