Ball's Hill
1900.
August 5
  Brilliantly clear morning, clouds gathering in late afternoon.
Light variable winds mostly easterly with long intervals of calm.
Morning & evening cool; middle of day warm.
  Purdie and I went out from 7.30 to 11 A.M. spending
most of this period in the woods on Holden's Hill. There
were lots of small birds there, mostly Warblers and Red-eyed
Vireos with a few Chickadees, a Tanager with young, a Downy
Woodpecker, two Flickers & some Jays.
 Morning walk
  The majority of the Warblers were Black and White Creeping and
Chestnut-sided but were at least two Blackburnians,
one a young in first plumage apparently,the other was old female.
Probably the Blackburnians were local birds although it is
possible they had come down from further north.
  The Tanager was still in red plumage but it had
a patch of yellow feathers on each side of the breast which
looked like recently assumed feathers of the autumnal dress.
It was anxious about a young bird which was near at
hand and it flitted close about us calling chirp and erecting
the feathers of the crown into a loose crest. The young
Tanager uttered at short, regular intervals a querulous, painstaking
call which at a distance sounded like Tre - e,near at
hand like cher - rng or teher - e and which was very like the
hunger call of a young Grosbeak (Habia) only more guttural
(or perhaps I should say nasal) in quality. We did not 
see or hear the Northern Tanager at all.
 Tanager with young
  Most of the birds just mentioned were collected together in
a mixed flock. The Red-eyed Vireos sang finely & well
and one of the Chickadees whistle phoebe many times.
