  Cloudless with light N to N.W. wind. Ther [thermometer] 52 [degrees]  -  6 A.m.
73 [degrees] - 1 P.M., 59 [degrees] - 8 P.M.
Arrival.- Yellow billed Cuckoo.
  In A.M. (8-10) walked to Davis Hill by the river paths
and back around Ball's Hill. Found only common
birds and not many of them.
  To Barrett farm via Davis's Hill in P.M. Heard the
first Cuckoo, a Yellow-bill, in the Barrett pasture.

  Visited the Partridge's nest in the Barrett run and
found it all right with no additional eggs. The bird
rose at 10 yds. distance flew about 10 feet (she had
to fly to get clear of the dense huckleberry bush)
then dropped to the ground and rose until out of sight
crossing several open spaces and moving in
a crouching position with her head close to the ground.
This behavior was so nearly similar to that of the
bird that had the nest with 13 eggs last season that
I am satisfied they are one and the same individual.

  Heard two Thrashers today one behind Ball's Hill
the other in the Barrett pasture. In the dense young 
pines near Pulpit Rock an Olive-backed Thrush was in full
song at sunset making the woods ring.

  As I was paddling up from Davis's Hill in the
evening twilight I heard Greater Yellow-legs whistling
and saw a pair of Black Ducks flying over Ball's Hill.
Apple trees in nearly full bloom to-day.
