6 and 7, and at Glen, on December 9, I saw several coveys. 

 None were found on the high plateau, but all were seen in 

 the lower valleys. 



4. Pedweoetes phasianellus campestris Ridgway — Prairie 



Sharp-tailed Grouse. 



These birds were seen only on the evening of November 

 27 on the plateau at the head of Squaw canyon, where a 

 flock of eighteen or so passed me on their way toward some 

 roosting place. A single individual had been observed some-

5. Circus hudsonius (Linnaeus) — >]\larsh Hawk.

 narrow summit of the ridge. 



9. Falco peregri)ms anatuin Bonaparte — Duck Hawk. 



The only record I have of this species is on December 8 

 w'hen one of the hawks was noted flying over the hills be- 

 tween Crawford and Fort Robinson. It was reported by 

 Professor Bruner in 1903 as probably breeding about eight 

 miles west of the fort. 



10. Falco colinnhariiis Linnaeus — Pigeon Hawk.

 the birds suddenly stopped their chattering, flocked to-
