10 PROCEEDINGS OF THE NATIONAL MUSEUM vol.80 



Nelson ^" does not definitely record this cormorant from St. Law- 

 rence Island, but writes that it is the " commonest of its kind 



* * * about the shores of the various islands in Bering Sea 



* * *." Bent records it as breeding on St. Lawrence, and Bailey 

 found the birds " fairly abundant at St. Lawrence Island, where they 

 were nesting along the cliffs below Sivunga, the first week in July." 



Collins brought back four specimens, three adults and one fully 

 grown immature just beginning to molt from the brown plumage to 

 the lustrous violet and greenish black of the adult state. This imma- 

 ture bird was a male, shot on July 22; two of the adults are without 

 data; the last adult, a male, was collected on October 11. All were 

 taken at Gambeil. 



The year-old immature bird is in an early stage of molt, although 

 it was collected so late in the summer. It would seem that this 

 species is as variable in its molting season as is the double-crested 

 cormorant, P. auritus aurltus, of which Lewis ^^ writes as follows : 



The time of beginning of the molt out of the first winter plumage varies much 

 in different individuals * * * it may begin as early as February, while in 

 the same birds it does not appear to begin ])efore the first of the following 

 August. Some individuals apparently complete it by the middle of July or 

 some afterwards, while in others it is still incomplete at the end of vSep- 

 tember * * *, 



Brooks found this species beginning to lay by June 2, on St. Law- 

 rence, " and eggs in an advanced state of incubation were taken 



* * * on June 28."
