1903.
May 20
  Clear with light S.W. wind. Oppressively hot; ther. 90 degrees
  There were numbers of birds singing close about the
house this morning and through the forenoon despite the
oppressive heat. Among them I noted a Lincoln's Finch,
Black poll Warbler, Blackburnian Warbler & Black & Yellow
Warbler. Later I heard a Canadian Warbler in the Pulpit
Rock woods & saw a Gray-cheeked Thrush at Ball's Hill.
The Lincoln's Finch, Canadian Warbler & Gray-cheeked Thrush
were all new to my list of this season.
Arrivals.
  The Lincoln's Finch spent the entire day near the
house being seen separately in the thicket of forsythia by
the wall and when driven from this flitting along the
bush-grown walls along the neighboring roadside. Once
we started it from the grass under the big elm.
It sang freely in the early morning and occasionally
up to nine or ten o'clock using invariably the same
song. This was so very close to that of a House Wren
that it might easily have been mistaken for it but
it was less loud and more broken involving some short,
silvery, trilling notes of a peculiarly delicate quality while
are not included among those given by the Wren.
  The bird like most of its kind was timid &
retiring dodging from cover to cover when closely followed.
  Forbush & I visited the Dove's nest found by
Gilbert the other day. It is built against the main
trunk of a dense young white pine about 8 ft above the ground.
The old Dove was sitting on the edge of the nest which
contained two young almost fully grown and feathered
