PEALE'S FALCON 67 



at Grand Island, Nebr. These are striking examples not only of a 

 curious east-to-west flight, but also of very rapid travel. One banded 

 at Kings Point, Yukon, on July 30, 1924, was shot at Duchesne, Utah, 

 on February 20, 1925. 



Casual records. — -An easy and powerful flier, the duck hawk has been 

 recorded many times outside of what is considered its normal range. 

 One was reported from Port au Port, Newfoundland, in 1911, and 

 there are several records, dating back to 1846, of specimens taken or 

 observed on Bermuda. 



Complete data are not available for many of the South American 

 records, but notice may be made of the following countries where the 

 duck hawk has been observed or collected: Dutch Guiana (April 19, 

 1922, Paramaribo); British Guiana; Brazil (Praia de Cajutuba, Sao 

 Paulo, the Lower Amazon and Caceres in March 1909); Uruguay 

 (Sta. Elena, Flores, and San Jose); Paraguay (Puerto Bertoni); 

 Venezuela (Los Hermanos Islands on January 9, 1909, and Bonaire); 

 Ecuador (Puntilla de Santa Elena, Pichincha, Pomasqui, Chaupicruz, 

 Carapungo, El Muerto Island, and a specimen from Cocos Island of 

 the Galapagos group, collected on January 26, 1902); Peru (Janin 

 and Chorillos); Chile (Santeyas, and Valdivia); and Argentina 

 (Provinces of Buenos Aires, Cordoba, and La Kioja, Los Ynglases, 

 and Cape San Antonio and Lomas de Zamora, Buenos Aires Province). 



A specimen also has been recorded that was collected about 1887 

 on Elizabeth Island, in the Straits of Magellan, Patagonia.

FALCO PEREGRINUS PEALEI Ridgway 



PEALE'S FALCON 



HABITS 



This dark race of the peregrine falcon is none too well understood, 

 as to its subspecific status and its distribution. Considerable doubt 

 has been expressed as to the validity of the name, because the type 

 is an immature bird taken, presumably, in Oregon; it is a dark-colored 

 bird but no darker than some dark specimens from eastern localities. 

 However, this need not necessarily invalidate the name, for the type 

 specimen may well have been, and probably was, a migrant from the 

 range of pealei, as now recognized.
