Finally, it seems probable that these birds acquire no ma- 

 terial increase of the red. area after the second summer, and 

 that the extent of red is not dependent on age." 



(C. E. A.) 



Loxia curvirostra minor. Crossbill. 



Resident in the mountains ; locally common. 



Aiken found several about St. Peter's Dome in June and 

 July, 1907; also at Palmer Lake, June 26, 1907. Allen and 

 Brewster reported seeing a flock of about thirty at Austin's 

 Bluffs, April 26, 1882, and also noticed a few both there and 

 elsewhere at both earlier and later dates. Two birds taken at 

 St. Peter's Dome on June 13 were apparently just completing 

 their moult, and one taken at Palmer Lake, June 26 was in the 

 midst of moulting. 



Loxia curvirostra stricklandi. Mexican Crossbill. 



There is in the Aiken Collection a male Crossbill col- 

 lected on Turkey Creek, May 22, 1874, which is much larger 

 than the other birds just mentioned, and has a much larger 

 bill. Sclater referred this to stricklandi, while Oberholser calls 

 it bendirei Ridgway, but this latter subspecies has not as yet 

 been recognized by the A. O. U. There is a female in the same 

 collection belonging to the same form, and having a label with 

 the same date, but which was really taken in the White Moun- 

 tains, Arizona, in 1876, by Aiken. 



Leucosticte tephrocotia tephrocotis. Gray-crowned Rosy 

 Finch. 



Winter resident ; irregularly common. 



This species, in common with the two succeeding species 

 of Rosy Finch, is a winter visitor with us, but quite uncertain 

 in its occurrence. Probably they are fairly regular in their ap- 

 pearance in the mountains, but lower down, below the foot- 

 hills, they do not come so often, though Aiken has collected a
