Summer residents of our Place.
  55. Red-shouldered Hawk: Seen or heard
frequently especially about the farm & also
at Ball's Hill. No nests found. The nest on
edge of Davis Swamp where a brood was
heard last year was not occupied this
season. I have never known a pair to
breed twice in the same nest, or even in
the same woods, in this neighborhood.
  56. Carolina Dove. Exceptionally numerous in early
April but I think only one or two
pairs settled to breed. Forbush found a 
nest with 2 eggs on Pine Ridge May 16 but
it was afterwards robbed probably by Jays.
I found a bird which acted as if she had
young, in the same woods on May 12.
  57. Ruffed Grouse: Rather more numerous than
usual. Birds drumming in Barrett Run,
Birch Field, at the Spring & in Davis Swamp.
Nest 9 eggs Ball's Hill Swamp. All eggs
hatched & brood seen later. Another brood
seen in Pulpit Rock woods.
  [Quail were heard whistling on the Farm
May 21 & 23 but none later.]
  58. Green heron. One or two pairs only - 
along the river
