i. HERRING GULL 



Larus argentatus 



Herring Gulls, not as migrants, but as 

 winter residents, are occasionally seen pass- 

 ing over northwestward to the Charles 

 River Basin and inland ponds, sometimes a 

 single bird and sometimes a dozen or twenty 

 birds. Very infrequently one or two have 

 been seen in the early morning flying in the 

 opposite direction. On April 25, 1906, 

 thirty were seen for a time to circle over the 

 Garden. Usually the occasional passages 

 over continue well into the month of May. 

 This was especially the case in 1905, when 

 the last bird noted passed over northward 

 in the morning of May 23. 



In the autumn, year by year, Herring 

 Gulls have also been seen, not daily, but 

 occasionally, as in the spring. The earliest 

 fall records are of one in flight on October 

 X 3t r 905, and of one on October 14, 1908.
