Hoffman.] 172 [October 6, 



27. Chondestes grammaca Bon. Lark Finch. 



Not as common as the two preceding species. Found farther 

 away from the Agency. 



28. Molothrus pecoris Swain. Cow Bird. 



Not of frequent occurrence. Several pairs found associating with 

 a flock of XanthocepJialus icterocephalus in the vicinity of the corral 

 and stables; also found miles north of the Agency, at the herders' 

 camp and corral. Found it again on Rose Bud Creek, west of Fort 

 Rice, where I also found an egg, in nest of Calamoapiza bicolor. 



29. Agelseus phoeniceus Vieill. Red- winged Blackbird. 

 Very rarely seen. 



30. Xanthocephalus icterocephalus Baird. Yellow- 

 headed Blackbird. 



Very common. Immediately after their appearance at the Agency 

 and vicinity, I collected quite a number of skins of males, of which 

 some had the yellow of dark orange, and others nearly a cream white 

 (except the head). 



31. Sturnella ludoviciana var. neglecta All. Meadow 

 Lark. 



Common. Found several times in the surrounding prairie, but I 

 think accidental. The note of this variety is exactly similar to that 

 of the same species, as it occurs in Nevada. 



32. Icterus spurius Bon. Orchard Oriole. 

 Scarce. Saw but two pairs. 



33. Icterus Baltimore Daud. Baltimore Oriole. 

 Occasionally observed amongst the willows and cottonwoods on 



the island. 



34. Icterus Bullockii Bon. Bullock's Oriole. 



Rather common all along the timbered river bottoms. (Rare above 

 Fort Pierre, Hat/den). More or less frequent all along the river, to 

 Fort Rice, Heart River, Yellowstone River, etc., see also Allen 

 " Nat. Hist. Montana and Dakota (Yellowstone Expedition), 1873." 



35. Quiscalus purpureus Licht. Crow Blackbird. 

 Frequently seen, though rare. 



36. Corvus corax Linn. Raven. 

 Not often seen in this vicinity. 



37. Corvus americanus Aud. Common Crow. 

 Rather common.
