BIRDS OF THE PACIFIC DISTRICT. 43 



Part of the notes included here may belong under the 

 next species but without specimens it is impossible to 

 determine.] 



38. Falco peregrinus pealei Ridgw. PEALE'S FALCON. 

 Habitat: Oregon and northward. 



39. Falco columbarius Linn. PIGEON HAWK. 



British Columbia. John Fannin. Summer resident; 

 not common. 



Cooper, 1860. Seems to be rather uncommon in the 

 Territory. I shot one in June, 1853, and did not see 

 another until April, 1855, when they had just arrived at 

 the Strait of Juan de Fuca. It doubtless breeds in the 

 Territory. 



Suckley, 1860. About the 1st of August this bird be- 

 comes very abundant in the vicinity of Fort Steilacoom, 

 Washington. During the summer and autumn of 1856 

 I obtained a number of specimens in different stages of 

 plumage. 



Walla Walla. Brewster (Bull. N. 0. C., vii, 227.) 

 Varieties suckleyi and richardsonii collected by Capt. 

 Bendire. 



Newberry. We found it paired and nesting about the 

 Klamath Lakes, and it likewise occupies all the region 

 south of the Columbia in Oregon. 



Henshaw, 1879. "Richardsonii" noted in several 

 localities in Oregon and northern California, and two 

 specimens in immature plumage were taken. 



Camp Harney. Bendire. Rather rare; nest contain- 

 ing young, May, 1876; the only nest I have seen. 



Ridgway. Seen on but three or four occasions. 



Central California. L. B. Rare winter visitant in 

 valleys and foothills; probably very rare summer resi- 

 dent of the fir forests; one seen on Castle Peak near 

 Summit, July 1st, 1885.
