BIRDS OF IVIGTUT. "21 



being specific, as assumed by many systematists. The mat- 

 ing of gray and white birds, and the occurrence of young 

 birds of both colors in one nest, certainly point in that 

 direction. 



If, however, as Mr. Hagerup thinks, the white-colored 

 birds are mainly found in summer in North Greenland, 

 while those breeding in the southern section usually wear 

 the darker plumage, then the two might be ranked as geo- 

 graphical races. 



The suggestions are interesting, but the evidence offered 

 is too slight to assist materially in solving the problem that 

 these birds present to scientific ornithologists. M. C.] 



DUCK HAWK. 



FALCO PEREGRINTJS ANATT7M. 



I have not seen a single living example of this species a.t 

 Ivigtut, only the skin of one shot a few years ago. From 

 Frederickshaab I obtained the skins of two young birds shot 

 in the fall of 1886, also the skin of an adult female shot 

 April 21, 1888, at her nest, which contained two eggs. Be- 

 sides this I obtained one egg taken on the 1st of May, 

 1888. 



This species is said to be much more dangerous to the. 

 Pigeons than is the Gyrfalcon. 



SNOWY OWL, 



NYCTEA NYCTEA. 



A rare winter visitor. In January, 1886, a fine Owl al- 

 most wholly white was taken. When wounded it attacked 

 the man who shot it.
