I Cambridge, Mass. 
1099. Three adult males in Fresh Pond on the morning of the 
December. 14th and a solitary female on that of the 17th. These are 
the only occasions on which I have seen Whistlers in Fresh 
Pond since January, 1091 when during a protracted spell of 
severe cold a small flock frequented a space of open water 
about the fountain for several days in succession. Those 
noted this month kept rather apart from the Black Ducks. I 
did not see day of them dive. 
On the Back Bay between the two bridges that connect 
Boston with Cambridge Whistlers have been present about daily 
during the present month but in rather smaller numbers than 
usual. I counted 40 birds there on the 29th. Their favorite 
feeding grounds this autumn are just below Harvard Bridge on 
the Boston side. On the Cambridge side where they used to 
congregate the water has been deepened considerably by dredg- 
ing during the past two years and, no doubt, most if not all 
of the feed destroyed.
