Cambridge, Mass.
1901.
April 4
  Cloudy with light rain beginning at 10 A.M. Ther 42 degrees
at 8 A.M.
  Took a walk immediately after breakfast. Found
an extraordinary number and variety of birds in the
neighborhood of Gray's woods or, to be more definite,
along Larch Street between Brattle Street and Huron Avenue.
There were several Robins, two pairs of Bluebirds (I saw
a third pair just behind the Lowell house at Elmwood),
a Chickadee, two Song Sparrows, five or six Tree Sparrows,
several Juncos, a pair of White-bellied Nuthatches,
a Crow-black bird, several Crows, a Meadow Lark
(in full song near the Brick schoolhouse), a Downy,
a Flicker and a Kingfisher (rattling in the direction
of Fresh Pond.) A third Song Sparrow was singing 
behind the Ole Bull house on Brattle Street. The Tree
Sparrows were singing gloriously.
  The Nuthatches were in a large hickory tree and
I saw one of them fly repeatedly to a hole
that seemed admirably adapted for mating purposes
and peep into it. Once the bird went into it
nearly out of sight.
  It is years since Bluebirds have been so numerous
about the outskirts of Cambridge. The birds seen
this morning acted as if they were settled for
the season and the female of the pair seen
at Elmwood alighted on the edge of a hole in
an old apple tree and seemed about to enter it
when she noticed me & flew away. All three of
the males were warbling.
