BREWSTER: BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 89 



Falco mexicanus Schleg. 

 Prairie Falcon. 



Hierofiilco mexicnnus Belding, Proc. U. S. Nat. Mus., V. 1883, 533, footnote (Mira- 



flores ; Cape St. Lucas ; San Jose del Cabo). 

 Falco mexicanus Bryant, Proc. Calif. Acad. Sci., 2d ser., II. 1889, 281 (Miraflores ; 



Cape St. Lucas ; San Jose' del Cabo). 



According to Mr. Ridgway, this Falcon was taken by Xantus at " Miraflores 

 November 25; Cape Saint Lucas, December 14 ; San Jose del Cabo, Decem- 

 ber, January." It was not met with by Mr. Belding, nor certainly identified 

 by Mr. Frazar. Mr. Bryant saw a pair about a cliff" at Comondu in 1888, a 

 single bird on Santa Margarita Island on March 2, 1889, and " a pair nesting 

 in a high cliff" at San Esteban on April 18, 1889. The Prairie Falcon breeds 

 rather commonly in California and Oregon, and ranges south into Mexico. 



Falco peregrinus anatum (Bonap.). 

 Duck Hawk. 



Mr. Frazar, who seems to have been the first to meet with the Duck Hawk in 

 the Cape Kegion, saw a few birds in February and March at La Paz (where one 

 specimen, an adult female, was obtained) and others, in October and Novem- 

 ber, at San Jose del Cabo and Santiago. In the northern part of Lower Cali- 

 fornia the species has been "found nesting in the cliff's along the coast at 

 several places from San Carlos landing to San Quintin by Mr. Anthony, who 

 saj's they are more common in winter " (Bryant). 



The Duck Hawk inhabits the entire continent of America wherever the 

 local conditions are suited to its requirements. 



Falco columbarius Linn. 



Pigeon Hawk. 



Aesnion columbarius Beldixg, Proc. U. S. Nat. Mus., VI. 1883, 351 (La Paz). 

 Falco columbarius Bryant, Proc. Calif. Acad. Sci., 2d ser., II. 1889, 281 (La Paz). 



Several Pigeon Hawks were seen in autumn at San Jose del Cabo and Sant- 

 iago by Mr. Frazar, the earliest date of observation being September 17, the 

 latest November 17. The collection contains a typical specimen from each 

 of these localities. Mr. Belding has reported the capture of a bird at La Paz 

 in January, 1883. The species was not met with by either Mr. Bryant or 

 Mr. Anthony. It ranges southward in winter to northern South America, and 

 breeds chiefly north of the United States.
