12.1. Point Baukow (jill. Lp'-us ha 



rrovianus. 



^' 







Range. — Northwest coast from Bering Sea to Point Barrow. 



This species is almost 



^^— .^^ * .-^ - identical with the Glau- 



"^ ' .. ' cus Gull, averaging per- 



* ^ haps a trifle smaller. 



Its standing as a dis- 

 tincit species is still 

 (luestioned and has not 

 yet been decided satis- 

 factorily. Early in June 

 their nests are built on 

 remote islands in Ber- 

 ing Sea. These nests 

 are the same as the last 

 species, large piles of 

 vegetation, hollowed on 

 top for the reception of 

 the eggs. The eggs 

 have the same varia- 

 tions in color and mark- 

 ings as the Glaucus 

 Gull. Size 3 x 2.10. 

 Data. — Her sell el Is., 



Alaska, July 1, 1900. Nest made of seaweed and grass; placed on the ground.
