There are many of these in winter, though they retire to breed’ in 
summer. They roost in circles on the ground. I have seen a patch 
of ground fifteen feet in diameter completely covered with their ex- 
crements. I think they resort to the same place many nights in 
succession, unless disturbed. I heard their “booming” several times. 
It seemed to come from a very great distance. A very fine male in 
my collection weighed four and one-half pounds before skinning. 
Their flesh becomes tainted with the sage on which they feed, and 
renders them disagreeable to some palates. 
“ Common in the northern part of the territory.” — C. H. A. 
113. Lagopus leucurus. 
“Said to be common on the Snowy Range. The following de- 
scription of the nest was given me by an old miner, who claimed to 
have found one near the top of the range in June. Nest composed 
of leaves and grass, placed on the ground among bushes on a side 
hill. Eggs fourteen in number, light bluish-brown spotted with 
dark brown.” —C. E. A. 
114. Grus americanus. 
“ Seen occasionally during their migrations.” — C. E. A. 
115. Grus canadensis. 
“ Common during the migrations.” — C. E. A. 
116. Ardea herodias Linn. 
“ Common summer resident.” — C. E. A. 
117. Botaurus lentiginosus. 
“ A single specimen observed.”— C. E. A. 
118. Atigialitis vociferus. Kiil-Deer. 
I saw four of these birds around a small mud puddle which was 
caused by arecent rain. They flew off on my approach, and I saw 
no more of them. They were not common, as the country is not 
such as they prefer. 
“Very common since March 1st. Lay four eggs among the gravel 
in the vicinity of the water.” — C. E. A. 
119. Atgialitis montanus. 
“Found in pairs in the table lands.” — C. EH. A. 
120. Gallinago wilsoni. 
“Common during the migrations. A few remain through the 
winter.” — C. I. A. 
121. Recurvirostra americana.
