EMBERNAGRA.—SPIZA. 415 
We have few notes of the habits of this species, but it doubtless inhabits the edges of 
low-lying tropical forests, living on or near the ground. Mr. Nutting says it is abun- 
dant near Los Sabalos in Nicaragua, where it frequents brush-heaps at the edge of the 
forest 1,

Mazatlan (Grayson ®*).— 
According to Grayson, this species is a winter visitor to the neighbourhood of 
Mazatlan, where it is numerous in some localities, occurring from December to April. 
Its notes, he says, have a faint resemblance to those of the Towhee Finch (Pipilo 
erythrophthalmus). It passes much of its time among the weeds in old fields and bushy 
places, feeding upon various kinds of seeds, including those of the silk-cotton®. Its 
range does not extend to the southern parts of Mexico, Guanajuato being the limit 
recorded in this direction 9. 
In Arizona £. chlorura occurs as a spring and autumn migrant, remaining neither in 
summer nor winter. Its summer resort, where it breeds, is the Rocky Mountains and 
the eastern slopes of the Sierra Nevada. Here Mr. Ridgway describes it as a charac- 
teristic species, and one of the most abundant of the Fringillide. He considers its 
powers of song of high merit. The nest (not described by Brewer) is placed from 
18 inches to 2 feet from the ground, among the thick bushes of a species of Sympho- 
ricarpus. ‘The eggs are an exact oval, white, with a bluish tint, and profusely marked 
with a cloud of fine dots of a pinkish drab 2. .
