  There were two Golden-winged Warblers singing
on the farm to-day, one at the foot of the
hill to the eastward of the barn this forenoon,
the other in the blueberry pasture across the road
all day long. The latter bird ceased singing this
evening at about 7.20 or before it had begun to
grow dark and sometime before the Song Sparrows,
Field Sparrows & Towhees ceased. Between 7 and 7.20
he gave the flight song three times, presumably
in the air although I did not once see him in
the act. I noted this song carefully on this occasion.
Either my previous impressions of it have been based
on careless observation (as I think was the case) or
it varies considerably at different times. On each
occasion this evening it consisted of either two or
three sets of twittering notes, ecstatic rather
than musical & each followed by the usual zee-e-e. In
should write it thus: - Twi-twi-twi-twi-ti-zee-e-e,
twi-twi-twi-twi-ti-zee-e-e, twi-twi-twi-twi-ti-
zee-e-e. There was also connecting these repeated phrases
one or two short stuttering notes so low as to be
scarcely audible.
  For several evenings past a number of Robins - at
least a dozen I should say - have assembled soon
after sunset in the dense blueberry & birch thickets
below the field in front of the house, evidently
to roost. They make a great clamor calling excitedly
for fifteen or twenty minutes but not singing.

  The Bats are back in the loft over the shed. I saw
one come out of it last evening & found ten in a cluster there to-day.
