BIRDS OF IV1GTUT. 11 



often in company with Black Guillemots. During the entire 

 winter there were only a few small flocks to be seen on the 

 fjord, but large numbers were reported wintering at Arsuk. 

 The last were observed at Ivigtut on the 22d of May in 

 two flocks of about one dozen each. As Dr. Oesterbye 

 found them on July 15, 1888, at the so-called " bird-cliff" 

 of Kangarsuk, about 62 N., it may be that they breed 

 there. 



RAZOR-BILLED AUK. 

 ALCA TORDA. 



This I have not seen at Ivigtut ; but, according to Dr. 

 Oesterbye, about five hundred pair breed at the above- 

 named " bird-cliff," whence I obtained its eggs and a skin. 



DOVEKIE. 



ALLE ALLE. 



A winter visitor, not common at Ivigtut, but at times 

 abundant about Arsuk. In the fall of 1886, it arrived at 

 the same time as Briinnich's Murre, with which it often 

 associates. One day sixty-five Murres antf two Dovekies 

 were shot from the edge of the ice, which gives approxi- 

 mately their relative numbers. In 1888 no Dovekies were 

 seen about Arsuk after the close of March. 



PARASITIC JAEGER. 



STERCORARIUS PARASITICUS. 



Two examples one a dark bird, the other with a light- 

 colored body were often seen in the summer of 1888 over 

 the fjord, hunting the Kittiwakes. They probably had a 

 nest in the neighborhood.
