117. Aquila chrysaetos (Linnaeus) 



Golden E.\oi>e 



A permanent resident throughout the state. Formerly common, now rather 

 rare. Reported by most observers from various localities scattered over the 

 entire state. Nests mainly in the ])ine iiills and badlands in the e;istern jiart of 

 the state, and in the mountains in the western half. Seldom seen in the valleys 

 or on the prairies in summer, but frequently common in such places in winter. 



Nesting data: Pryor's Fork of the Yellowstone, near Fort Custer, a nest 

 found with eggs May 22, 1883, l)y Dr. J. C. Merrill (Rendire, 1892, p. 268). 

 Other detailed accounts of the nesting of this species in ^Montana ma.v be found 

 in the writings of Cameron (1905b, pp. ir)8-167, and 19081), pp. 251-268).

 bers in the mountains of the northwestern part. Commoner in Novembei- and 

 March than at other seasons, but evidently foimd throughout the year. 



Sunnner records: Rare on the Yellowstone and .Alusselshell (Allen, 1S74, 

 p. 65). Seen on the Jlissouri (Grinned, 1876, p. 650). Generally distributed

 (Badey, MS). Belton, June 30, 1915, and Dutton, June 23, 1916 (Dubois, MS). 

 There is little that is definite about the nesting of this species in the state, nor 

 any dates to show when it nests. A pair are reported to have nested on the 

 Boulder River near Big Timber (Thomas, MS).
