Concord, Mass.
1909.
March 28
  Forenoon chilly with N.E. wind and heavy rain changing
at times to sleet. Afternoon cloudy & gloomy. Wind N.W. and
narrow strip of blue sky showing along western horizon at sunset.
  There were three Fox Sparrows at the seed bed behind the
house to day as against one yesterday but the Juncos had
decreased one half for there were only four five to-day in
place of the ten that we had yesterday. Song Sparrows
had increased slightly in numbers for I heard two singing on
the farm and saw another at Mr. Howe's.
  Robins seem to have arrived in large numbers some
time during to-day. When I got to Mr. Howe's at 4.30 P.M.
he told me there had been fully fifty feeding on his
lawn only a few minutes before. As I walked back
after sunset (6.10 - 6.30) I heard them singing &
calling in every direction far and near. Two birds were
in full song, the others had more or less wheezy voices
as is common when they first come. I saw a number
fly past, low down, as they crossed the road into our
berry pasture where they seemed to be going to roost in
the blueberry bushes.
Robins arrive in force
