LONG-WINGED SWIMMERS 



l<2.1. Point Barrow Gull. Larus barrovianus. 



J*~~ -** 



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- 

 tinct species is still 

 questioned and has not 

 yet heen decided satis- 

 factorily. Early in June 

 their nests are huilt 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.
