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. Specimen 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 5th, 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, re ~ 

 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. 



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

 southeast of Lander.
