Cambridge, Massachusetts.
1901.
January.
(2).
  (Notes made by Walter Deane in the absence of
William Brewster).
  Various circumstances have prevented me from making
more than a very few observations on the bird life in Cambridge
 and vicinity during the month of January. Fresh Pond
was not entirely closed by ice till about the middle of the
month but even then the Herring Gulls and Ducks resorted
there in considerable numbers to rest upon the surface of the
ice. Records were made by me and others all through the
month and but twice were no Gulls reported. Their numbers
varied from 1000 on the 1st, 9th and 25th to none on the 12th.
500 were counted on the 26th.  
  Black-backed Gulls were seen on Fresh Pond as follows: -
one on the 6th by W. Deane; three on the 9th by Master
Kidder; one on the 24th by Mr. G. C. Deane.
  The largest number of Black Ducks seen was 150 which I
counted on the 1st at 10 A.M. I could easily distinguish the
Red-legged and the Gray-legged birds. No other water fowl
were observed on the Pond during the month.
  Mr. N. A. Francis saw a Red-breasted Nuthatch in Brookline,
on the 19th.
