 very similar Arctic Tern, it is jjossible that this 

 species may liave been present. 



A Tern colony is in some respects a unit. The 

 alarm of one bird is shared by all, and before the 

 boat's keel grated on 

 the sandy beach of the 

 largest Weepecket, the 

 snowy - br(.'asted birds, 

 which in a group were 

 resting there, had taken 

 flight, and with their 

 singular call told all the 

 other Terns on the is- 

 land of mjr invasion.

 flock overhead, pro-

 remains near their home ; it rings in the ears for 

 days afterward, and one need only to recall it to 

 form a clear mental picture of a sky full of hov- 

 ering Terns. Occasionally this monotone was punc- 

 tuated by a loud, reedy each as a Roseate Tern 

 dashed by, or as some half- distracted bird, whose 

 nest was doubtless near, screaming, dived close to 

 my head with a sudden, startling swish. It seemed 

 almost as though the bird woiild pierce me with its 

 .sharply pointed bill ; and if it could have managed 

 to go througb the rim of my hat without damage to 

 either of us, I should have been very glad to have
