Cambridge, Mass.
1899. 
Nov. 29
  Clear, mild, nearly calm up to 9 A.M. a fresh W. [west] wind
during the remainder of the forenoon. Afternoon hazy and calm.
  Spent most of the forenoon at Fresh Pond watching
the water fowl assembled there. Gulls and Ducks
intermingled covered an area of at least twenty acres
W. Deane counted 770 Gulls and I 150 Ducks. A few 
Gulls were coming in from time to time at 9 A.M.
and at about 11 A.M., when the west wind started
and began to ruffle the pond, at least one third of
the gulls rose high in air and departed in the
direction of Boston. Our count was probably made 
at about the time when the birds were present in 
the greatest numbers.

  At least ninety per cent of the Gulls were old birds
(a sad commentary on the results of the past breeding
season.) I scrutinized nearly every one of them carefully
with my double telescope and as far as I could make 
out, all but one were Herring Gulls. The exception was 
a Larus glaucus in the "hutchinsi" plumage, ie wholly
white without trace of blue in the mantle or of
mottling anywhere. I could see this distinctly with the 
glass for the bird was not far and and in a good
light. I could also see that its bill was larger then
that of the Herring Gulls which were swimming near
and flesh-colored with a dark band near the tip.
The bird spent most of the time during which I
watched it in sleeping although it also preened
its feathers once or twice.

  Many of the Herring Gulls also slept by spells but
the majority swam slowly about or "rode at anchor."
