80. Tetanus flavipes (Gmelin) 



Yellow^legs 



Abundant migrant throughout the state in fall. Less common in spring. 

 Fall records are from practically every part of the state, and by nearly all 

 observers. Where definite dates of migration are given, they are as follows: 

 Spring records: Teton County, ]\Iay 8-23, 1912 (Saunders, 1914a, y>. 130) ; Bit- 

 terroot Valley, May 30-31, 1912 (Bailey, MS). Common at Fort Keogh in spring 

 (Thorne, 1895, p. 213). Fall records: Rocky Mountains, August 16 to 29, 1874 

 (Coues, 1874b, p. 642) ; Billings, and en route to Miles City, August 12-13, 1900 

 (Jones and Dawson, 1900, p. 31) ; Teton County, August 5 to September 4, 

 1911 (Saunders, 1914a, p. 130) ; Button, August 29, 1916 (Du Bois, MS). 



Thorne reports that this species may breed at Fort Keogh, indicating that 

 he evidently found it in summer. Coues records a specimen on the Milk River, 

 July 25, 1874. There is no evidence that it really does breed, and summer birds 

 are probably only very early fall migrants. Silloway (1903a, p. 19) contrasts 

 the abundance of this species with the last mentioned, by the statement that in 

 Fergus County T. flavipes occurs in the proportion of three or four to one of 

 T. melanoleucus. 



81. Helodromas solitarius solitarius (Wilson) 



p] ASTERN Solitary Sandpiper 

 A migrant, probably throughout the state, and commoner eastward, but in 

 many cases not clearly separated from the western subsjx'cies. iiut two definite 

 records ai'e known. These are from Miles City, August 14, 1900 (specimens col- 

 lected ])y Hedges are in the collection of the University of ^lontana), and from 

 Gold Creek, Powell County, August 20, 1910 (Saundei-s, 1912a, p. 24). 



82. Helodromas solitarius ciimamomeus (Brewster) 



Western Solitary Sandpiper 

 A common fall migrant throughout the state, occurring also in spring in the 

 eastern i)art. The only spring records are from Terry, Islay 7, 1903, and May 9, 

 1904 (Cooke, 1910a, p. 60). Fall records are abundant everywhere ; some of them 

 in July or early August have led observers to believe the species breeds in the 

 state. Dates for fall migration are as follow^s: Glendive, July 28, 1873 (Allen. 

 1874, p. 66) ; head of Milk River and west of Sweet Grass Hills, August 10 to 

 29, 1874 (Coues, 1874b, p. 643) ; Teton County, August 5 to 18, 1911, and San 

 River, August 13, 1912 (Saunders, 1914a, p. 130); Flathead Lake, August 8,
