river, Tongue river, Running Water, Big Sandy, and several 

 general references; McCarthy recorded a specimen from the 

 North Platte river; Williston reports them rather abundant 

 in the vicinity of Medicine Bow; Jesurun reports them com- 

 mon in the vicinity of Douglas ; Bond finds them common about 

 Cheyenne ; Fisher gives the following interesting records : 

 "Specimens taken at Cheyenne, Aug. 21, 1888,. stomach. con- 

 tained 10 grasshoppers, 45 beetles and other insects. Speci- 

 men taken August 23, 1888, stomach contained 35 grasshoppers, 

 20 beetles, etc. Specirtien taken Aug. 23, 1888, stomach con- 

 tained 15 grasshoppers and 5 beetles." Cary states that he 

 has found colonies in the vicinity of Newcastle about prairie 

 dog towns. I have found this species near the following places 

 in the state : Sundance, Moorcroft, Douglas, Newcastle, Uva, 

 Rock Creek, Casper, Fort Washakie, Otto, Laramie, and Fort 

 Steele. 



CUCKOOS, ETC. 



388. Coccyzus erythrophthalmus (Wils.). 

 Black-billed Cuckoo, 



Probably resident; but quite rare. But two collectors* 

 have recorded specimens from this state. Dr. Jesurun reports 

 that they are frequently seen during migration- along the val- 

 ley of the North Platte river and that he captured one May 

 21, 1893, and a second May 28, 1895-. 



C. H. Trook reports that he took two specimens on the 

 Big Horn on June Sth, i860. It is probable that the birds 

 taken by Trook were breeding; but we have no data on this 

 point. Williston while collecting at Lake Como, 1879, '"^" 

 ports hearing the yellow-billed cuckoo but he did not take any 

 specimens. It is quite probable that it was the black-billed 

 that he heard, in place of the yellow-billed. The California 

 variety has not been taken ; but may be expected. 



*0n the last of May, 1902, I noted this species on the Little Popo Agie river, twelve miles- 

 southeast of Lander,
