First Swallows
  The birds about the house were singing more freely 
and numerously this morning than at any time before this
season, the Fox Sparrows taking the most prominent part
in the delightful chorus with Robins, Bluebirds, Chickadees, 
Song Sparrows, Juncos & a Flicker adding their voices.
Birds singing in early morning
  I walked to Birch Field about 7.30 without noting anything
new to my spring list but soon after getting back I
heard the first White-bellied Swallow and presently
saw it, at first darting about among the apple trees
and then perched in an elm. In the afternoon I found
a Hermit Thrush in Birch Field within one hundred yards
of the spring where I saw a Hermit, probably the same
individual on March 29th.
Hermit Thrush
  During a drive to Walden Pond with Edward Emerson
this forenoon (9-11.45) I saw or head about 6 Bluebirds,
12 or 15 Fox Sparrows, 3 or 4 Robins, 1 Meadow Lark &
2 White bellied Nuthatches (1 at the old Emerson place, the
other in Fairyland woods). Song Sparrows were fairly
numerous but I saw very few Robins and almost 
no Juncos.
Birds noted during drive to Walden Pond
  There were 16 Fox Sparrows at our seed bed to-day
and 5 or six Juncos. An English Sparrow female came to
it for the first time.
  Hundreds of Wood Frogs in the pond below
the orchard most of the afternoon.
