  To Ball's Hill at 9 A.M. with Mr. Hubbard taking the
two canoes. Just below Flint's bridge we came upon a
large mixed flock which included several Bluebirds, a
White-bellied Nuthatch, Chickadees (singing) a Pine Warbler (singing
softly) two or three Black-polls, a number of Chipping &
Song Sparrows, one Savanna [Savannah] Sparrow, a Goldfinch, a
Downy Woodpecker and a Cat bird. They were congregated 
in the tops of the elms on both sides of the river 
and kept flying back & forth across it, shuttle wise.

  At Ball's Hill we found an equally large flock
of woodland birds three Red-eyed Vireos, three Tanagers,
a great number of Chickadees and Black-polls, a
Red-start two Downy Woodpeckers and a Pine Warbler. They were among the
oaks and pines along the south slope of the hill. Near
the cabin a Wilson's Thrush started up from among some
ferns and several Song Sparrows were dodging about in the
bushes near the path. Jays screamed at intervals and
a Red-shouldered Hawk occasionally.
  The Scarlet Tanagers were an old female accompanied
by her two young which, although in full autumn plumage,
followed their mother about closely and begged continually
for food uttering a monotonous hue, very like the call
of a young Purple Finch, and a low, wheeze sound which was
so nearly like that made by some young Red-eyed Vireos
that I had just been watching that I could detect no difference.
When approached by their mother the young Tanagers would
squat down on thin perches & quiver their half-opened wings. I did
not see her feed them.
