In the district of Ajo, this Tinamou is not common, and 

 is now almost entirely confined to the coast-belt. In the 

 nortlij where it is more abundant, its clear whistling note is 

 often heard.

The Riiea is almost gone from the Ajo district, but may 

 &till be found in the rough country along the coast, where 

 I have seen as many as nineteen together. A few are more 

 or less preserved in many of the estancias. 



The nest is usually placed in a thick patch of long grass, 

 and the incubating male usually sits closely, rising with a 

 rush and outspread wings from under the horse's nose. 



One nest that I visited contained nineteen newly-hatched 

 chicks and two unfertile eggs, and it was from these that I 

 oljtaiucd the nestling specimen.
