Hooded monkey
The division of living beings into systematics is a continuous subject of research. Different systematic classifications exist side by side and one after the other. The taxon treated here has become obsolete due to new research or is not part of the group systematics presented in the German-language Wikipedia.
The hooded monkey ( Sporophila melanops ) is a now invalid bird species of the tangaren (Thraupidae) from Brazil , of which only the male type specimen from 1823 is known. The specimen was caught by Josef Natterer in October 1823 from a flock of other finches on the edge of a lake 15 km north of Registro do Araguaia on the Rio Araguaia on the central western border of the state of Goiás in southern Brazil and is now in the Natural History Museum Vienna . The species is thought to be possibly extinct, but the British ornithologist Guy M. Kirwan was able to show in a genetic study from 2016 that Sporophila melanops is not a valid taxon , but probably a hybrid .
The specimen has a body length of 11 cm and is so unusually colored that it has been mistaken for a hybrid or an abnormal specimen of the yellow-bellied monkey ( Sporophila nigricollis ) by some scientists . The wing length is 55 mm, the tail length 41 mm and the beak length 8 mm. The male has a black crest and throat. The top is olive colored. The underside shows a dirty brownish yellow. It was in the deep moult. The related yellow-bellied monkey has a light yellow underside in comparison and the black color extends to the upper breast.
The species was first described in 1870 by the Austrian ornithologist August von Pelzeln .
