Specimens from southeastern, southwestern, and northwestern Costa 

 Rica were compared, and show no signs of variation ; neither do they 

 differ from birds from Santa Marta, Colombia. The species has a 

 wide range and seems very constant throughout. 



Its habits are very similar to those of the preceding species, except 

 that it is much noisier, frequently uttering its loud, characteristic call, 

 always when disturbed and often of its own accord, thus unwittingly 

 guiding the hunter to it. It is more abundant than the preceding, 

 although most persistently hunted, seeming to be more wary and better 

 able to escape. They range over the whole of the lower portion of the 

 country and extend to much higher altitudes than Crax panamensis, 

 often being met with up to four or five thousand feet. I shot a fine 

 large bird at Ujurras de Terraba right up in the territory of Chamcrpetes 

 unicolor, at not less than six thousand feet above sea-level.
