  3. Galeoscoptes carolinensis. - The pair of catbirds have remained through
the month. The male has sung but very little and as a rule only
feebly and brokenly although he was in full voice on the 7th, 10th, 11th,
and 15th. Young of the first brood were seen (never more than one at
a time) in the garden on the 1st, 14th, 15th & 16th; those of the second
brood left the nest on the 28th. I think there must have been several but
I never saw (nor heard) more than one at any one time. The first
nest was built in a smoke tree just behind the house about five feet
above the ground; the second some three feet higher & eight feet distant
in the top of a syringa. The young Cat-birds of both broods were
very noisy for a week or more after leaving the nest, calling almost
constantly for food uttering monotonous tsi, tsi, tsi very like the
chirp of a young Warbler. The parents were anxious & bold coming
close about us whenever we approached the young crying week, week
& sometimes making a short, harsh screaming sound.
Garden Birds
  During his first singing period, in May & early June, the male
Cat-bird mimiced the pee-e-e of the Wood Peewee and the paap
of the Night-hawk frequently & very perfectly. Not once during this
time did I heard him give the imitation of the song of the Wood Thrush
or Bobolink both of which were constantly uttered last year, but
twice in July of this year he gave in my hearing a full bar of
the Wood Thrush's notes thus showing that he must be the same
bird which bred here in 1901.
  4. Sialis sialis. - W. Deane heard a male warbling over the Garden on the 29th.
  5. Parus atricapillus. - I heard one whistling "phoebee" on the 12th.
  6. Dendroica aestiva. - Present through the month. Heard singing
feebly & brokenly nearly every day.
