The Birds of El Paso County, Q)lorado 569 



Junco oreganus shufeldti. Shufeldt's Junco. 



Winter resident ; not common. Arrives and departs at the 

 same time as the other Juncos, extremes being October 15 and 

 April 10. 



For the names of this and the two following species we 

 follow Ridgway rather than the A. O. U. Check-List as it seems 

 to us that the treatment of the Juncos in the latter is exceed- 

 ingly unsatisfactory. 



Shufeldt's Junco is not uncommon during the winter but 

 is not found in any such numbers as the Pink-sided or Gray- 

 headed Juncos, or even the White-winged in its abundant 

 seasons. In the field, without the use of a glass, it is often 

 difficult to distinguish between this and the Intermediate and 

 Montana Juncos, except when one is very close. At a near 

 view, the very black head and pink sides of the Shufeldt's 

 make it easily identified, but the females are difficult if not im- 

 possible. As a writer in Bird Lore says: 



"For the female of the species is more puzzlin' than the 

 male." 



Warren took one at Lake Moraine in December, 1906, 

 and a black-headed Junco of some sort was seen there in 

 March, 1906. 



In migration this species is quite common. 



Junco montanus. Montana Junco. 



Winter resident; not common. Arrives and departs at 

 much the same times as the other Juncos. 



There are seven specimens in the Aiken Collection taken 

 at various date from October 25 to April 24. This is probably 

 the least common of our Juncos in Winter; in the migrations 

 it is more abundant. The males arrive from the south about 

 February 25 and are around for ten days or more, and the 

 females follow somewhat later in March.
