420 EXPLANATORY INDEX. 



In a wild state they are not so gregarious as the Curassows, 

 which are fond of assembling in large groups upon the 

 branches of trees. The Guans, however, although so closely 

 allied to the Curassows, are quite distinct in their habits, 

 leading comparatively solitary lives in the forest. They feed 

 mostly on fruits. 



Mr. C. B. Brown found a nest of the Hannaquoi situated in 

 a low tree. It was made of sticks, and contained four 

 speckled eggs, about equal in size to those of the common 

 fowl. 



The bird is easily tamed, and soon becomes domesticated 

 with -the poultry. It will even breed with them, and the 

 hybrid is said to be exceedingly quarrelsome and pugnacious.

HITIA. As this tree is mentioned in conjunction with the 

 siboalalis, it is probably an Eperna.

HOUTOU (Momotus Braziliensis). This is a very remarkable 

 bird, if only for the peculiarity in the central tail-feathers, 

 attributed by Waterton to art, but really due to Nature alone. 

 As may be seen by the illustration, a portion of the web in 

 the two central feathers is wanting, and the bird really does 

 strip the vanes from the stem, as mentioned by Waterton. 

 There are, however, several birds, notably the Variegated 

 Bee-eater of Australia, which have similarly-shaped tail- 

 feathers, but in which the peculiar formation is due to Nature, 

 and not to art. It is a fly-catching bird, sitting quietly on a 

 branch until an insect flies near, when it darts from its perch, 

 catches the insect, re-seats itself, and then swallows its prey. 



The plumage of a fresh specimen is bright blue and green
