70 [degrees] Fine chorus Robin voices Perfect
  Brilliantly clear, perfectly windless for most 
part; warmest day of the year thus far.
Vegetation advancing fast. Larch and Parkman
apple veiled in tender green young foliage
by nightfall. Horse chestnut and lilac buds
bursting into leaf. Squills at best. Crocuses
past and wilted. Grass intensely green.
  Garden birds. Robins silent through day &
only a single pair in sight but soon after
sunset they began singing far and near, keeping
it up until 7 P.M.. At least 4 or 5 males
could be heard at once from our open doors.
Not for years have I listened to so full a
chorus of their delightful voices in this
neighborhood. A Flicker shouting all day,
in calatapa [catalpa] by Museum, mostly. White thr. [White-throated Sparrow]
singing loudly but crudely. Several
Grackles on ground. Jay screaming, Crow
cawing, Downy [Downy Woodpecker] tchick-ing. A few H. Sparrows [House Sparrow].
  Wrote letters & read war news. Called on
the Spelmans in their garden at noon.
C. [Caroline Brewster] walked with me in our garden in P.M.
Miss Allyn at dinner. E. [Elizabeth R. Simmons] read "Pride
& Prejudice" this evening.
