two eggs in one of these nests and hatched & reared her young. Most
of the nests in the orchard were robbed and dismantled by something
- the Chipmunk Squirrels, I suspect. When the birds were building 
in late April & early May the males sang but little. In late
May they sang freely and well. Two or three pairs nested on
the Ritchie place & there was one pair established at Ball's Hill. 
Summer Resident Birds.
Cat bird. - Gilbert saw a Cat bird by the roadside on
Punkatasset on April 27, an early date. After the migration
was over I could find only two pairs on my land, one at Ball's
Hill near "Bensen's landing", the other at the Farm. The Ball's
Hill birds were not seen after May 27. The pair at the farm were
noted as late as June 18 & 19. They evidently had a nest either
in the Syringa hedge behind the house or in the forsythia bush in front
of it for I saw them constantly in both places.
  Brown Thrasher. - Less numerously represented than usual.
At the Farm a male sang through the first half of May on the
hillside below the old barn and during the same period I repeatedly
saw a pair near Bensen's knoll and heard a male in song across
the river behind my stone boat house.  
  Bluebird. - I saw fewer Bluebirds than usual this spring and heard
literally no full, free, joyous singing, even in March. On April 1st I
watched a pair eating barberries greedily in our lane although the weather
was clear at the time & there was no snow on the ground.
On April 18 a pair began building in a bird house on the Ritchie
place and on the 23rd another pair began their nest in a box in
our flower garden. Young were reared in both these nests but I fear
that a third pair which built in a box in an apple tree across
the road near our pond had less success for I did not see them
