  11. Yellow Warbler: - As usual a pair nesting in the
garden at the farm, another in shrubbery by the
roadside at the Ritchie place, a third in the
thickets along the river at Ball's hill.
  12. Chestnut-sided Warbler: - At least five pairs at
the Farm, two on the wooded slope east of the
old barn, two in the Blueberry Pasture, one
in Barrett Run. No doubt there were others in
the Ball's Hill region of which I took no note.
  13. Blackburnian Warbler: - Two males singing regularly
in the white pine woods south of Pulpit Rock.
On June 7th, after hearing both these birds in their
usual places, I found a third nest, not two
minutes later, in the Barrett Run near the Ritchie's 
house.
  14. Black-throated Green Warbler: - Two males singing in
Pulpit Rock woods, two on Pine Ridge, one in 
Prescott's Pines, one in the pine grove opposite Ball's
Hill on south side of river.
  15. Pine Warbler: - One male in Pulpit Rock woods, another
on Davis Hill, a third on Pine Ridge, a fourth
on Ball's Hill, a fifth on Dakin's Hill.
  16. Oven bird: - Much less numerous than usual. Two or
three pairs in the farm woods and five or six
pairs elsewhere would passably be a large estimate.
