'82 YACOU GUAN. 



mentioned by Temminck has the general colour 

 of the plumage black, shaded with reddish and 

 slight hues of purple : round the eyes is a very 

 small naked space, which does not communicate 

 with the cere on the beak ; it is also surrounded 

 with a circle of small black feathers : the forehead 

 has a deep black space : the feathers of the crest 

 are white on their edges, and black towards the 

 middle : the quills are singularly truncated, and 

 their points subulated. 



Two of these birds were for a long time in a 

 menagerie in Holland : they were very familiar and 

 quiet, and lived with great harmony with poultry : 

 their cry was a kind of whistle. 



The Yacou is found in Guiana and Brasil, on the 

 borders of the rivers Amazon and Plata ; but is 

 not common : it makes its nest on the ground, 

 and hatches its young there ; though at other 

 times it is generally seen on trees : when pleased 

 or taken notice of, it erects its crest and expands 

 its tail.
