Stellula calliope is by no means a common bird in Mexico, where it appears to be 

 strictly confined to the highlands, from the mountains of Guerrero and the Valley of 

 Mexico northwards. 



Within the United States it would appear to be much more numerous, at least 

 during the summer months, when no doubt it breeds. 



The colour of the throat readily distinguishes this species, no other showing the 

 white bases of the feathers of the throat amongst the glittering rosy spots at their 

 ends. The female much resembles that sex of Atthis heloisce, but may be recognized 

 by its longer bill and by the bases of the lateral rectrices being greyish rather than 

 cinnamon.
