Concord, Massachusetts.

Mass.
Concord. - Morning clear. Afternoon hazy. A strong
chilly N. E. wind all day. Brisk showers 5 – 6 P.M.
  Rose at 6.30 a.m. On opening the door I found
the bushes along the river front literally swarming
with birds. There were certainly thrice as many
as yesterday but the species represented were precisely
the same save that the White-throated Sparrow were
all gone and the Canadian Warblers more numerous.
The latter, Wilson's Black-caps, and Black-poll
Warblers were all singing freely. On the hill I
could hear a Grosbeak & a Tanager. The whistling
of Yellow-legs came from the Great Meadows & I
afterwards saw four T.[Tringa] melanoleuca fly past down
river.

migrants?[/margin]
  After breakfast walked around the hill. The wind
had now risen and most of the birds had sought
shelter on the N. W. side where the budding oaks
with their salmon & pink leaflets just unfolding
were simply alive with Warblers. Among them I
saw three Black & Yellow Warblers. Canada Flycatchers
were very numerous & I saw one female. A pair
of Rose-breasted Grosbeaks was flitting about uttering
a low tender love call to each other, the male, a
remarkably fine performer, occasionally singing. I
saw three Doves. Two, a pair, are now to be found
in a certain young white pine at any hour of
the day. I have started them from it a dozen
times at least in the last two days. There is no
nest but I suppose they are preparing to build one
there. A flock of at least 30 Swifts hawking behind hill
Returned to Buttricks' at 5.P.M. rowing up in the rain.
