3. Our surprising failure to obtain any information regarding 

 the fall migration. There seems to be little doubt that the Yellow- 

 billed Loon does not leave its supposed breeding ground in the fall 

 through the region we visited, which is evidently the highway only 

 in the spring. 



4. There seems reason to believe, from evidence as cited above, 

 that the coast of southeastern Alaska may still be profitably 

 scrutinized to yield information regarding the migratory move- 

 ments of the vellow-billed Loon.

NOTES ON SOME MAINE BIRDS. 



BY ARTHUR H. NORTON. 



The following notes refer to species of more or less unusual 

 occurrence within the boundaries of the state of Maine together 

 with records of two species new to the State list. One of the latter 

 not having been previously recorded in the United States. 



Stercorarius pomarinus. Pomarine Jaeger. — While not venturing 

 to criticise the general statement, that the present species is probably the 

 rarest of the three jaegers,^ from local experience the statement comes as 

 a surprise. On this coast, between Saco Bay and West Quoddy Head, 

 the Pomarine Jaeger has been the only species found at all commonly. Of 

 course jaegers are not common compared with gulls of the common 

 species, yet almost any day in summer, spent at sea three or more miles 

 beyond the bays, will usually show one or more Pomarine Jaegers, while 

 the other species are seldom seen. 



It frequently enters the broad bays, and is often to be found in tlie vicin- 

 ity of the large tern colonies harrying the terns. The birds are well 

 known to all fishermen and distinguished by an obscene name. 



On the Maine coast they occur throughout the summer. 



My e.xtreme records are May 29 (1914) and September 22 (1913). 



In late August and earl}' September there are usually evidences of a 

 migratory movement, as an increase of birds is noticed for a week or more.
