40 PACIFIC COAST AVIFAUNA. [No. 4 



Spizella atrogularis (Cabanis). Black-chinned Sparrow. 



On April 4, 1902, I heard a Black-chinned Sparrow singinsf on a 

 steep hill-side near our camp. The bird was not seen, buj the loud 

 characteristic song- was kept up for some time, and I know of no other 

 species in this region with a note at all like it. Some ten days previous 

 to this I saw and heard several in the foothills of the Santa Catalina 

 Mountains, near Tucson, so I do not think I could have been mistaken. 

 This is the only occasion on which I have had any indications of the 

 presence of this species in the Huachucas, and it must be of rare occur- 

 rence there. 



Junco hyemalis (Linnaeus). Slate-colored Junco. 



Occurs in limited numbers in the winter in company with caniccps, 

 incanisi and fhiirberi. I took but four specimens all told ; two males 

 taken on February 18 and 24, respectively, and a male and female taken 

 on March 24, all in 1903. Possibly three or four others were seen ; none 

 being observed at a higher altitude than 5500 feet. 



Junco hyemalis shufeldti Coale. Shufeldt Junco. 



I have three Juncos from this region, two males and a female, which 

 Mr. Ridgway has identified as belonging to this race. These were all 

 taken at a low altitude in flocks composed of the various species of junco 

 wintering- in the mountains, and though these were all the specimens 

 secured they may have been fairly abundant, being associated with 

 tluirhcri as thev were; for the two races are bv no means easv to dicr- 

 entiate, even where specimens are secured, and in the field it is prac- 

 tically impossible to do so. 



Junco hyemalis thurberi Anthony. Thurber Junco. 



As this bird is usually listed as a mere straggler in Arizona, I was 

 surprised at finding it as numerous as it was in the Huachuca Mountains 

 during February and March. 1903. At this time it was probably the 

 most abundant species of junco in the mountains, beinq- particularly 

 numerous in the oak regions below 5500 feet, and occurring in limited 

 numbers up to the highest parts of the range. On February 21, I saw 

 a few on the divide of the mountain at about 9000 feet. After the middle 

 of March they began to disappear, and after the first of April but an 

 occasional small b.uncli of half a dozen or so was seen, the last observed 

 being on April 19. Specimens secured dififer in no wise from birds in my 

 collection taken in various parts of Southern California. 



Junco mearnsi Ridgway. Pink-sided Junco. 



I found this species quite common during February and March, 1903, 

 occurring in the large flocks composed of the various species of juncos 

 that were in the mountains at the time ; but restricted almost entirely 

 to the lowest part of the range, no specimens of incarnsi being taken 

 above 5500 feet. Though not as abundant as some of the other species, 

 it was fairly numerous up to the third week in March, all that were seen 

 after that being an occasional stray bird, usually in a small flock of can- 

 iccps, which lingers in this region longer than anv of the other non-resi- 

 dent species of juncos. The last Pink-sided Junco seen was a female 

 shot on April 15. In the specimens secured there is considerable varia- 

 tion, particularly in the females, in the shade of pink of the sides, and the 

 area covered by it ; in some this color extending far up on the sides of the 

 neck, or meeting across the breast.
