COMMON RHEA 235 



almost exterminated wherever the nature of the 

 country admits of their being chased. When on the 

 Rio Negro I was so anxious to obtain specimens of 

 this Rhea that I engaged several Indians by the offer 

 of a liberal reward to hunt for me, but they failed 

 to capture a single adult bird. I can only set down 

 here the most interesting facts I was able to collect

 known. 



When pursued it frequently attempts to elude the

 Rhea, but it is sooner exhausted. In running it 

 carries its head stretched forward almost horizon- 

 tally, which makes it seem lower in stature than the 

 allied species hence the vernacular name of " Short 

 Ostrich/* It is found in flocks of from three or four 

 to thirty or more individuals. It begins to lay at the 

 end of July, that is, a month before the Rhea ameri- 

 cana. Several females lay in one nest, which is merely 

 a slight depression lined with a little dry rubbish ; 

 as many as fifty eggs are sometimes found in one 

 nest. A great many wasted or huacho eggs, as they 

 are called, are also found at a distance from the nest. 

 I examined a number of eggs brought in by the 

 hunters, and found them vary greatly in shape, size,
