 Found throughout much the same region as the preceding, and with 

 very similar habits. 



Both species appear to become common in Eastern Middle Arizona 

 at about the same time ; their general amval from their northern breeding 

 grounds not taking place till in early October. From this time, they 

 are generally dispersed over the country, seeking the plains and low lands 

 generally, and apparently finding in such localities an abundance of food 

 for their wants in the seeds of the weeds and grasses, and such insects as 

 they can discover at this season. At Camp Apache, both species were very 

 numerous the latter part of October, frequenting here chiefly the stubble 

 fields, and such spots as in the East the Titlark invariably selects in the • 

 interior country. Though the similarity of their wants and habits brought 

 both species to the same spots, I noticed that they rarely mingled ; and, 

 tliouo-h occasionally a few of one species would be found in a flock of the 

 other, these exceptions were quite rare, and generally the flocks maintained 

 their individuafity intact.
