128 EXPEDITION TO POINT BAKROW, ALASKA. 



760. URIA GRYLLE (Linn.) Briinn. 

 BLACK (JiTILLEMOT (Su'kllbicu). 



During the season of open water we only saw one or two of these birds, always in full black 

 plumage, and at some distance from the shore. In November and December, however, in fact as 

 long as there arc any pools and "loads" of open water, these birds in winter plumage are to be found 

 in considerable numbers, usually in small flocks. They only leave us when the ice becomes solidly 

 packed by the winter gales, and curiously enough are not to be found during the spring migra- 

 tions. A number were taken in the winter of 1882, and with one exception were all the young of 

 the year. 



764. LOMVIA ARRA (Pall.) Bp. 



THICK-BILLED GUILLEMOT (A'tpa). 



This species, the "Crowbill" of the whalemen, readies Point Barrow only as a rather rare 

 straggler. They were sometimes seen at the lead of open water in the early spring and during the- 

 summer at some distance from the shore. One was taken as late as December 9, 1S82, out among 

 the broken ice by one of the seal hunters. We found them quite plenty nt the Seahorse Islands 

 on our return voyage, and of course extremely abundant about Cape Lisburne.
