70 THE BIOLOGY OP HARDING COUNTY 



Greater Scaup Duck (Marila marila). Abundant migrant along 

 the rivers (Catron). 



Lesser Caup Duck (Marila af finis}. Very common migrant (Cat- 

 ron). 



Buffle-head (Charitonetta albeola). Abundant migrant. 



Snow Goose (Chen hyperborus hypcrboreiis). Xot commonly 

 seen, most frequently in spring (Catron and others). 



White-fronted Goose (Anser albifrons gambcli). Catron reports 

 this to be the most abundant goose ; a common migrant. 



Canada Goose (Branta canadensis canadensis'). Grinnell found 

 this species breeding abundantly along the Little Missouri and 

 other streams in 1874. Catron reports they were fairly com- 

 mon till 1890. Xow infrequent and seen only as a migrant. 



Hutchins's Goose (Branta canadensis hutchinsi). Xot common 

 during migrations (Catron and otherr). 



Bittern (Botaurns lentiginosus) . A few here in wet seasons. 



Great Blue Heron (Ardca hcrodias hcrodias). Both Grinnell and 

 Catron reports that this species occasionally breeds along 

 the Little Missouri River. We saw several in 1912 though 

 none before. 



Green Heron (Butoridcs fircsccns). One seen July 13 on Little 

 Missouri River. This is a large extension of range and the 

 bird seen was probably a wanderer. 



Black-crowned Night Heron (Nycticarax nycticorax nac-rius)- 

 Several young of this year were seen on the Moreau River 

 during the third week of August. They were probably wan- 

 derers. 



Whopping Crane (Grus aincricana). Reported to be not infre- 

 quently seen during the spring migration. 



Sandhill Crane (Grus mexicanus). Grinnell states that this 

 species was occasionally seen on the plains, and that its nests 

 were numerous in the pines of the Black Hills. The present 

 status of Sandhill and little Brown Crane may be described 

 as "occasionally an abundant migrant." 



Virginia Rail (Rallns firginianns). One pair bred in a small 

 reedy patch in the Cave Hills in 1910 and one pair in West 

 Short Pines 1912. 



Sora Rail (Porzana Carolina}. One was seen in the slump marsh 

 on the east side of the East Short Pines Sept. 7, 1912.
