 }yilsonia pusilla, ALLEN, Bui. Miis. Conip. Zool., 1872, 175. 



Stilted by Mr. Allen to be a common inhabitant of the Colorado Mount- 

 ains, breeding from about 8,000 feet up to about timber line. Said also by 

 Dr. Coues to be a common summer resident in the mountainous districts of 

 Arizona from May till September. The species has never been met with 

 by our parties other than as a spring or fall migrant, as which it is ex- 

 ceedingly abundant, and seemingly pursues its way north or south without 

 reference to locality, being found fi-om the mountain tops to the lowest 

 valleys. That some remain in Arizona to breed, retiring for this purpose to 

 the summits of the high mountain ranges, seems quite probable; for I have 

 met with individuals early in August which could hardly at this date have 

 made their way from very far north, while, by the middle of this month, 

 the species abounds everywhere, being much more widely dififused and in 

 ffreater numbers than it ever is in the East.
