58. Quiscalus purpureus Licht. Crow Blackbird. Purple 

 GrakleV 



Abundant on the Missouri at Fort Rice, common along Heart 

 River, and on the Yellowstone as far up as we ascended. Very 

 abundant about the mouth of Tongue River. 



CORVlDiE. 



59. Corvus corax Linn. Raven. 



More or less common from the Missouri to the Musselshell, beino - 

 seen almost daily, but nowhere very numerous. Seen on the divide, 

 between the two Porcupine Creeks, far out on the naked barren 

 ridges in the Bad Lands. 



60. Corvus amerieanus Aud. Common Crow. 



Common wherever there is timber. Contrary to what is usually 

 supposed, we found the ravens quite common where the crows were 

 very abundant. Quite large flocks of crows and small parties of 

 ravens were frequently in sight along the Yellowstone at the same 

 time, there being apparently no hostility nor antipathy between them. 

 We robbed a raven's nest July 5th, near the Heart River, within 

 hearing of a large flock of crows that had assembled a few hundred 

 yards distant in the timber, to celebrate, apparently, some great 

 occasion. 



61. Pica caudata var. hudsonica All. Magpie. 



Not common. A few seen at distant intervals throughout the 

 journey. 



TYRANNIDiE. 



62. Tyr annus carolinensis Bd. King Bird. Bee Martin. 

 Very common along all the wooded portions of the streams. One 



of the most common of the woodland birds. Seen frequently after 

 the breeding season far out among the sage brush on the plains. 

 Departs for the south during the last week in August. 



63. Tyrannus verticalis Say. Arkansas Flycatcher. 

 Exceedingly abundant wherever there is timber, far outnumbering 



even so common a bird as the T. carolinensis, and more numerous 

 than any other of the tree-nesting species. After the breeding season 

 seen far away from the timber among the sage brush. This, like the 

 preceding species, disappeared about the end of August. 



64. Sayornis Sayus Bd. Say's Flycatcher. 



During the breeding season only solitary pairs were seen, usually
