THE NATURAL HISTORY SURVEY. 29 



The Kittiwake is a very rare winter visitant. Mr. E. W. 

 Nelson observed it at Chicago, and he with Dr. P. R. Hoy report 

 seeing it at Waukegan, IlHnois. However, I can find no record 

 of its capture prior to that of the specimen now in the museum 

 of The Chicago Academy of Sciences. This specimen is a young 

 bird which has the black patch on the lower part of the neck 

 and the band on the tail well defined. The tail has a slightly 

 forked appearance. It was shot by Mr. Chris. Wagner, and pur- 

 chased for the Academy. 



A gull supposed to be the Kittiwake has been observed on the 

 lagoons of Jackson Park, Chicago, in the month of April, 1904. 



While the visits of the Kittiwake are rare, it is quite apt to 

 appear in our vicinity during especially severe winters. Its 

 range includes the Arctic regions but in winter it passes south- 

 ward to the Great Lakes.

Mr. Robert Ridgway says that the Glaucous Gull is an Arctic 

 bird which occasionally visits Lake Michigan in the winter. 

 In the writer's collection there is a specimen in the pure white 

 plumage of the second year which was captured at Millers, In- 

 diana, August 8, 1897. When shot, the bird was alone and 

 flying along the beach of Lake Michigan. Three specimens 

 were also taken by Dr. P. R. Hoy several years ago at Racine, 

 Wisconsin. 



The Glaucous Gull is a bird of the Arctic regions which passes 

 southward in winter to the Great Lakes and Long Island.
