ICTEEUS BALTEMORE, (L.) Daucl. — Baltimore Oriole. 



Arrives about May 19, and remains until September 1. Is seen h 

 small numbers about the woods all over tbe bead of the Coteau ; breeds^ 

 bere. 



The specimens measure as follows: 



^ No. 640, 9, n.75x7.75. 

 No. 6tJ0, $, lL90y 7.70. 



QuisoALTJS PURPUEEUS, (Bart.) Licht. — Furple GracJcle. 



This bird arrives about April 17, and from that time until its disapJ 

 pearance at the end of October is found in large numbers all over thej 

 I)rairie and about buildings, as also in woods, where I have often founc 

 it particularly numerous, and under such circumstances as to lead me to] 

 believe that it was indulging in that carnivorous ijropensity observed^ 

 by Mr. Gentry and mentioned on page 204 of Professor Coues's Birds of 



the Northwest. 



COEVID^. 



CoRVUS CORAX, Linn. — Eaven. • 



The only Eavens I have ever seen on the " Coteau des Prairies " were 

 a pair I procured from Indians July 9, 1876 ; I believe they had been bred 

 in the immediate vicinity of the Post, to the north, as stated by the In- 

 dians, and also on account of their age 5 although it seems strange that 

 their occurrence could have escai)ed my notice in the careful scrutiny I 

 have given the region. 



CoRVUS AMERICANUS, Aud. — Common Crow. 



The Common Crow is a rare visitor to this region. It is occasionally 

 seen late in winter and in the early spring, but does not remain to mo- 

 lest the agriculturist. Much as elsewhere, the Crow api^ears as a very 

 wary, I might almost say knowing, bird : it is exceedingly difficult to get 

 within gun-shot range of it. At Fort Berthold, D. T., where I ob"s3rved it 

 in numbers in the spring of 1873, doing much damage to the young corn 

 and other parts of the crop, it was quickly driven from that vicinity by 

 l)oisoning corn and sprinkling it around the scene of their operations, 

 and although only a few dead birds were discovered, it took the hint and 

 left for a more agreeable abode. 



'Cyanurus cristatus, (L.) Sw. — Blue Jay. 



Is seen occasionally during the summer months in the heavily tim- 

 bered ravines on the slopes of the Coteau ; does not occur in any num- 

 bers. IS'ovember 30, 1878, 1 saw a single Blue Jay in the woods at Fort 

 Sisseton. This Jay was also in the vicinity of the Post as late as De- 

 cember 10. 



TYEANNID^. 



Tyuannus carolinensis, (L.) Bd. — KingUrd. 



^Arrives May 16, and departs about September 9; is very common dur- 

 ing the period of its stay. Breeds here.
