106. Bubo virginianus. Great Horned Owl. 
I was not successful in my attempts to get a full plumaged male 
of this species. They were quite common, and no doubt breed in 
that locality. They preferred the thickest pine trees, where they 
remained concealed during the day. A full sized young bird was 
shot in August out of a pine tree. It was devouring a small animal 
at the time. Its crop was filled with pieces of birds and animals. I 
frequently saw them flying in the air pursued by a flock of blackbirds. 
They seem to have particular resting places, like some hawks, to 
which they resort to devour their prey. On being driven from one 
tree they fly to another familiar place, and then back again. I was 
unable to find any nest. 
107. Otus wilsonianus. Long-eared Owl. 
But a single specimen was seen and shot on alow bush. A lot of 
magpies were on the same bush, and did not seem either to molest or 
be afraid of it. 
108. Athene hypugaea. Burrowing Owl. 
A specimen was shot with some ‘‘prairie dogs,’’ though they are 
rare in the Black Hills. ‘The above was the only one secured. ‘They 
are very common on the lower plains. 
109. Genaidura carolinensis. 
‘‘ Abundant on the plains, breeding in low bushes and on the 
ground. Begin to arrive about the first of April, and are very 
abundant by the last of the month.” —C. E. A. 
110. Tetrao obscurus. Dusky Grouse. 
There were but few of these birds to be seen during the summer, 
probably on account of their breeding. I saw several females and 
their young, which greatly resemble the young of the C. cupido 
(Pinnated Grouse). In the fall they go in flocks and rest on the 
ground, though some seem to prefer the trees. I did not get their 
eggs, but found many young ones. ‘Their flight is similar to C. 
cupido. 3 
‘¢ Said to be a common resident in the mountains.’ —C. E. A. 
111. Pediocaetes columbianus. Sharp-tailed Grouse. 
None were seen in summer. A few seem to pass the winter 
here. <A fine male shot January, 1870, is in my possession. They 
are not common in the hills, thauen they are more so on “ Laramie 
Plains.” 
“ Common in certain localities. Found in brush along the creeks.” 
—C. E. A.
