FALCO PEREGRINUS PEREGRINUS Tunstall 

 PEREGRINE FALCON 



Contributed by Francis Charles Robert Jourdain 



The European race of this species is included in the third and 

 fourth editions of the A. O. U. Check-List on the ground that it is 

 "casual in Greenland." Herluf Winge (1898) ascribes all Greenland 

 birds, from both west and east coasts, to Falco peregrinus Tunstall 

 var. anatum Bonaparte, i. e., the duck hawk. This was generally 

 accepted until 1926, when O. Helms published a little work on the 

 birds of Angmagsalik, based on the collections and notes of Johan 

 Petersen. Here he states that the "nomadic Peregrine" has reached 

 Angmagsalik and breeds there, but sparsely and only at intervals of 

 years. He records nests found in 1909, 1912, and 1924 and states that 

 Petersen had birds brought to him, shot from the nest on May 26, 

 1909, and a male, also shot from the nest on June 11, 1912. These 

 two skins were sent to Denmark, and Helms reports that the 1909 

 bird proved to be "a mature but not very old bird which, with its 

 unspotted breast, closely resembled the American form, whereas the 

 one shot in 1911 [1912?] was more like the European form." As all 

 writers are agreed that the West Greenland bird is the duck hawk, 

 this record is the sole evidence for the inclusion of the European bird. 

 It should be noted that this specimen was a breeding bird. 



E. Lehn Schi0ler in his great work, Danmarks Fugle, vol. 3, pp. 

 399-405, published posthumously in 1931, who had before him a series 

 of 19 adult males and 16 adult females from Greenland, including 

 specimens of both sexes from Angmagsalik, admits only the American 

 form (F. p. anatum) to the Greenland list. There is scarcely any 

 doubt that the two specimens described by Helms were included in 

 Schi0ler's survey, although there is a slight discrepancy in the date 

 of the second bird, which is given by Helms as 1911 in one place and 

 1912 in another, while Schi0ler records it as 1914; and, as he had also 

 splendid series of the European bird for comparison, his evidence can 

 be accepted without hesitation. The extreme improbability of two 

 races breeding in the same locality, when the nearest breeding station 

 of one of the two is over 1,000 miles distant, also provides strong 

 corroboration, and the race should be deleted from the American list.
