Concord, Mass
1903
March 15
  Cloudy most of the day with rain, piercing N. E. wind.
   Oldys departed for Boston by the morning train.
I walked to Ball's Hill with him and spent the
remainder or the forenoon rambling about in the 
neighboring woods. Heard a Creeper sing a few times.
Kinglets were calling in two different places. Chickadees
are the only conspicuous woodland birds now. They
seem to be unusually numerous although there were
apparently almost none in the same woods last
January.
  Early in the afternoon saw a flock of 5 Black Ducks
flying over Birch Field in a southerly direction &
started six Fox Sparrows in the Green Field. As
Gilbert & I were waiting at W. Bedford to take the
4.10 P.M. train back to Cambridge a male Marsh Hawk
appeared high in air. He kept on over Ball's Hill
and I noticed him until he was out of sight in
the distance. His course was due north & I have
little doubt that he was migrating.
  Small flocks of Crows were moving westward
at intervals all day yesterday and in a field
near Flint's Bridge we saw upwards of 60 walking
about on the ground. They were much less numerous
to-day.
  Five Crocuses were in bloom in front of the farm house
this morning and later I found a number of purple
"ladies delights" in full flower in the garden.
