Concord, Mass.
1906.
Dec. 5
  Cloudless, calm; early morning cold, temperature
above the freezing point at noon.
  Spent the day at Concord superintending the 
cutting of a lot of young white pines to send to Cambridge
for winter covering. We got them in the opening between
Ball's & Davis Hills. I paid no very close attention to
the work but, after the trees had been selected and marked
for cutting, I wandered widely through the woods traversing
Davis Swamp and visiting Ball's Hill & Pine Park. We
went through Birch Field on our way down in the
morning and returned to the wood and the Ritchie place
at noon. In the afternoon I did not go far away from
the house.
  The comparatively mild and perfectly calm weather and
clear sunshine made the conditions unusually favorable for
the birds and I saw or heard there in considerable number 
and variety as the following list will show.
  1. Golden-crested Kinglet. 2 in a flock on Pine Ridge, 2 in a flock in Pine Park, 1 in a flock at Ball's Hill.  
Also heard in Barrett Run & in Birch Field.
  2. Chickadee. - 2 in a flock at farm house, 3 in a flock in Barrett Run, 2 in a flock in Pine
Ridge, 6 in a flock (with a Golden-crest) at Ball's Hill. 
  3. White - breasted Nuthatch - 1 near the Old Manse, 2 in a flock in the
large elms at our farm house.
  4. Northern Shrike - One seen flying over the field in front of
Mr. Hutchins' house on Punkatassett Hill in Late P.M.
  5. Lesser Redpoll. - Heard at frequent intervals in forenoon on Pine
Ridge. On one occasion the calls evidently came
from the members of a large flock.
  6. Snow Bunting. - Nine birds seen flying over the fields between
Lars & Rudolph Petersen's as we were driving towards
the farm about 10 A.M.
