1921 BIRDS OF MONTANA 17.i 



First noted in Fci-g-us County in l!»(t:i, and at IlcU-nji in l!)ill' (Silloway, l!)0:!a, 

 p. 70). It reached Bozcnian, somewhere l)et\veen ISDS an<l I'.ldS (Saunders, 

 Iftlla, p. 4'_'i. It was statetl to l)e absent in northern .Montana in ]9l.)6 (Esta- 

 i)rook, litdT, p. l-'Hl. While it is entirely ahsent in wild eountry away from the 

 haunts of man, it is by no means limited to cities, but is found at any chister of 

 raneh buildini;s, where i;rain is scattered in sufficient (piantity to keep the birds 

 alive, 



HYPOTHETICAL LTST 



Marila mania (Linnaeus) 

 Scaup Duck 

 Found in larne numhers on Lake MacDonahf in Api'il, litis (V. M. Hailey, 

 1918, J). 5^). This is evidently a sight record. While 1 do not doui)t that this 

 species occurs as a migrant in ]\Iontana, all the records 'based on specimens prove 

 to be M. affiiiis, and the two species are too nearly alike to admit one to the list 

 on sight identification only. 



Somateria dresseri Sharpe 

 Eider 

 One shot at Glendive and identified by a Norwegian (Cameron, 1!)()7, p. IT)!)). 

 Since Mr. Cameron evidently did not see this bird, and the najne of the pei-.sou 

 \,iio identified it is missing, the recoi-d is best considered doubtful. 



Nycticorax nycticorax naevius (Hoddaerti 

 Bl.vck-crowned Night Heron 

 Two birds seen close to the North Dakota line in June, 1917 (Thomas, MS). 

 While this record is probably entirely correct, it seems best to leave the species 

 on the hyiiotlietienl list until a specimen has been collected. 



Himantopus mexicanus (Miiller) 



Hl,.\CK-NECKED StU.T 



A rare summer resident of the Lake Basin, ncai' Billings, i'l-eediug at Big 

 Lake and at other places in the vicinity (Thomas, MS). This is rather far nortn 

 of the known breeding range of this species. Mr. Thomas' observations were 

 first made in 1917. lie saw the birds again in 1918, and attempted to verify 

 the record by securing a specimen, but was unable to do so. I have therefore 

 jjlaced the species in the hypothetical list, with the liojie that the record will be 

 verified in the near future. 



Buteo borealis harlani (Audubon) 

 H.vRL.VN Hawk 

 Seen in Dawson County, August 25, 1905 (Cameron. 1907, p. 261:!). Since 

 this subspecies has been taken in North Dakota, its occurrence in eastern Jlonta-
