A^o.1.1 M'CHESNEY ON BIRDS OF DAKOTA. 77 



ably passing north diuing this time, and tarries but a few days in this 

 region. I have not observed it returning south. As in the case of the 

 Savanna Sparrow, I am unable to account for its presence here as a mi- 

 grant so late in June, as it certainly does not breed in this vicinity. 



JuNCO HYEMALis, (L.) Scl. — SiiowMrd. 



Is a regular winter resident. Arrives about IS'ovember 14, generally 

 with the first snow-storm, and disappears about April 16, with stragglers 

 seen until IMay 8. As a rule is quite common during this time, but through 

 mild winters but few are seen here. 



The specimens measure as follows : 



No. 602, ^, 11.75 X 6.90; wing 4.20; tail 2.85. 



No. 603, 2, 11.73 X 6.90; wing 4.23; tail 2.90. 



No. 604, ^,11.70 X 6.87; wing 4.20; tail 2.85. 



No. 696, 5, 12.20 X 7.00; wing 4.30; tail 2.70. 



No. 697, <?, 12.25 X 7.05; wing 4.40; tail 2.90. 



Spizella monticola, (Gm.) Bd. — Tree Sparrow. . 



Ajjpears Ax)ril 10 and remains until the end of October ; is very abun- 

 dant and breeds here. During early spring, belbre the trees have put 

 forth their leaves, it is one of the most familiar birds one meets about 

 the woods. 



Spizella pallida, (Sw.) Bp. — Clay-colored Sparrow. 



June 28, 1878, I shot a single Clay-colored Sparrow near the Post. 

 This is the only one I have met with in three years' collecting liere, and I 

 therefore conclude it is only of very occasional occurrence in this region. 



ZONOTmcHiA QUERtTLA, Gamb. — Harrises Sparrow. 



A single specimen of this Sparrow was secured May 21, 1878, near the 

 Post : its i)resence here I believe to be purely accidental, as in all my 

 collecting here I have met with but this one bird. 



Calamospiza bicoloe, (Towns.) Bp. — White-winged Blaclchird. 



Appears on the prairie about July 14, in quite large floclcs, and remains 

 until July 24, in this vicinity. Appears quite a strange bird, and selects 

 its feeding-grouuds with considerable care, for it is not found on the high 

 ground, but on the fertile grassy lower ground ; but not on the low moist 

 ground, however. 



EUSPIZA AMERICANA, (Gm.) Bp. — BlaeJc-tJiroafed liuntin<j. 



Is found here fi?om June 9 until July 2G in considerable numbers, 

 and I believe it breeds in this vicinity, but of this I have no positive 

 evidence. 



The sx)ecimens measure as follo^j^s : 



No. 666, ^,10.00x6.50; wing 3.13; tail 2.27; tars. 0.87; m. t. & c. 0.95; bill 0.r7. 

 No. 667, S, 9.90x6.25; wing 3.04; tail 2.10; tars. 0.80; m. t. & c. 0.86; bill 0..55.
