Selasphorus rufus is a winter visitor to the highlands of Mexico, where it arrives in 

 August and remains until the following spring. The remainder of the year it spends 

 in the Western States of North America, reaching British Columbia in its northern 

 migration. Its breeds during the summer months, and it is only in males from the 

 north that the full beauty of its plumage is seen. All specimens of that sex from 

 Mexico are in more or less faded and worn plumage. 



According to de Oca ^ it is abundant in the Valley of Mexico in autumn, at which 

 time Villada says it breeds ^^j but this statement, we think, requires confirmation, The 

 highlands of the State of Oaxaca are the extreme southern limit of the autumn 

 migration of this species. It is quite unknown in the highlands of Guatemala.
