Concord Mass.
1896
Nov. 20
  Clear and cold with high north wind.
  Spent the day at Ball's Hill as usual, sailing down 
in the morning and paddling home at evening.
The violent and piercing wind drove the birds
to cover and I saw nothing of much interest save
a fine pair of Red-tailed Hawks at Holden's Hill
perched on trees on the edge of the meadow about 100
yards apart. Both were adults in high plumage  with
deep red tails. They were doubtless the same birds which
I saw on this meadow on the 18th. Only the male
was there yesterday. They were not the same as the
pair seen near Davis's Hill October 24th for the [female]
of the latter was immature and the [male] larger & brighter
colored.
  A flock of over eighty crows spent the day on the
Bedford Shore every now and then rising from a cornfield
where they were feeding and circling with loud clamor.
