and birds. They are always armed with blunt arrows and bows, and 

 know, too, how to use them very effectually. 



In the following list I have added notes respecting each species, 

 stating whether common or abundant or rare, as will be seen upon 

 reference. 



1. Turdus migrator ius Linn. Robin. 



Rather scarce. But one pair was found breeding in the vicinity of 

 the Agency. 



2. Turdus Pallassi Cab. Hermit Thrush. 

 Saw very few specimens. Obtained but two skins. 



3. Turdus fuscescens Stephens. Wilson's Thrush. 

 •Several pairs were observed near the hospital for several days, and 



finally disappeared. 1 saw the species again at Fort Rice. 



4. Galeoscoptes earolinensis Cab. Cat Bird. 

 Common; and is found amongst the thickets nearly everywhere. 



5. Harporhynchus rufus (Linn.) Cab. Brown Thrush. 

 Not as abundant as the last species. Found two pairs breeding on 



the island, opposite the Post. 



6. Sialia arctica Sw. Rocky Mountain Bluebird. 



Not very common. Saw several pairs near the truck garden, in May. 



7. Polioptila coerulea (Linn.) Scl. Blue-gray Gnat-catcher. 

 Very rare; procured but one specimen. 



8. Parus atricapillus var. septentrionalis (Harris) Allen. 

 The only specimens I found were moving up the timbered bottom 



along Oak Creek. 



9. Sitta earolinensis var. aculeata Allen. Slender-billed 

 Nuthatch. 



The only specimen I saw was a mutilated skin obtained near the 

 head waters of Grand River, by a young Indian, and by him worn as 

 an ornament in a raccoon -skin cap. 



10. Troglodytes aedon var. Parkmanii (Aud.) Coues. 

 Western House Wren. 



Rather common. 



11. Anthus ludovicianus (6m.) Licht. Titlark. 



Found migrating southward late in September, and very abundant. 



12. Neocorys Spraguei Scl. Missouri Sky Lark, 



Saw no specimens near the Post, but was informed that they bred 

 at the head waters of Oak Creek. This species prefers marshy soil, 

 or where the grass is longer and denser than it usually occurs on the 

 prairies.
