A widely ranging species, resident in Mexico according to Sumichrast, who says that 
it remains throughout the year in the temperate region of Vera Cruz, where it breeds 
as freely as in the United States’. 
A separate race has been recognized by American authors as inhabiting Arizona, 
under the name of Spizella socialis arizone. This bird we should expect to find in 
the Sierras of Durango and in Western Mexico, but we fail to detect any differences 
between our examples from those parts and others from the Eastern States. Moreover, 
a specimen from Arizona seems to us to be the same in every way, having the chestnut 
head of the true S. socialis. Our series, however, of this western race is hardly good 
enough to enable us to speak very positively, but, so far as it goes, tends to show that 
S. socialis arizone will prove inseparable from S. socialis itself. ‘The name was based 
upon young birds, the striated heads of which had not given place to the chestnut 
crown of the adult. 
Though apparently a common species in Mexico, next to nothing has been written 
of S. socialis beyond a record of the localities where it has been observed, and these 
extend over a large portion of that country, as far south as the mountains of the 
isthmus of Tehuantepec, where, according to Mr. Lawrence, specimens of both the 
common and the Arizona race were obtained by Sumichrast in the months of September 
and January. 
* In Cuba it has only once been noticed, Dr. Gundlach having shot a female specimen
