Lesser Antilles (Trinidad); British Guiana (Mount Roraima and 

 Takutu Mountains); Brazil (Mixiana Island, Para' Itaraca Moun- -e. 

 tains, Marianna, and Rio Sapetiba); and Argentina (Buenos Aires, 

 Cape San Antonio, Rio Colorado, Rio Negro, Chubut Territory, 

 Puerto Deseado, and Tierra del Fuego). South to southern Argentina 

 (Tierra del Fuego); and southern Chile (Isla la Mocha). West to 

 Chile (Isla la Mocha, Nilahue, Marga-Marga Valley, Coquimbo, 

 and Viluco); western Bolivia (Caiza and Lake Aullagas); Peru 

 (Arequipa); Ecuador (Crater of Pichincha and Antisana); western 

 Colombia (Cali); Guatemala (San Agustin); Oaxaca (Tehuan tepee) ; 

 Nayarit (San Bias) ; Sinaloa (Mazatlan) ; Chihuahua (Lake Palomas) ; 

 and Arizona (Fort Huachuca and Tucson). 



The range as above outlined is for the entire species, which has, 

 however, been separated into two geographic races. The typical 

 form, Falcof.fusco-coerulescens, is widely distributed in South America, 

 ranging north probably to Panama. The northern form, F. j. sep- 

 tentrionalis, is found from (at least) Guatemala north through Mexico 

 to the Southwestern United States. The exact limits of the respective 

 ranges are imperfectly understood and some taxonomists recognize 

 two additional races in South America. 



While the species does not appear to be regularly migratory, the 

 individuals found in summer in the northern parts of the range with- 

 draw southward in winter. At this season it is not found north of 

 Sinaloa (Mazatlan) and southern Tamaulipas (Altamira). Similarly, 

 in southern Patagonia, there is a slight northward movement at the 

 onset of the southern winter.

According to the fourth edition of the A. O. U. Check-List (1931) the 

 kestrel is accidental in Massachusetts (Nantasket Beach) and Green- 

 land (Cape Farewell). As to the first record there is fortunately no 

 doubt. Charles B. Cory (1888) writes that a female of this species 

 was shot at Strawberry Hill, Nantasket Beach, Mass., on September 

 29, 1887, and after being seen in the flesh by Mr. Cory, passed into his 

 collection. With regard to the occurrence at Cape Farewell, the 

 evidence is less clear. There is no mention of the record in Hagerup's 

 paper (1891) on the birds of Greenland. It is significant that Herluf 

 Winge, who corrected several errors of identification in this work (see 

 Auk, 1891, p. 319) and published an authoritative work on the birds
