1902.
May 18
  Cloudless with light N.W. wind. Warmer even
than yesterday.
  As I strolled about through the orchard and near
the house for about half an hour immediately after
breakfast this morning I noted the following birds
singing: Robin 1, Bluebird 1, Thrasher 1, Chickadee 1,
Creeper 1, Nashville Warbler 1, Golden-winged Warbler 2,
Yellow Warbler 2, Black & Yellow Warbler 1 (in apple orchard),
Chestnut-sided Warbler 4, Black-throated Green Warbler 1,
Black-poll Warbler 1, Oven bird 2, Redstart 2, Red-eyed
Vireo 1, Yellow-throated Vireo 1, Warbling Vireo 1, Chippy 1,
Song Sparrow 1, Grosbeak 1, Indigo bird 1, Oriole 2 males 1 female,
Least Flycatcher 1, Great-crested Flycatcher 2. The only
birds in this list which were obviously bound further
north were, of course, the Black Poll & Black & Yellow
Warblers and the only new arrival was the Indigo Bird.
Migrants.
Arrival of Indigo Bird
  In the afternoon I drove to Ball's Hill and rowed
thence up river to the Buttericks. I heard at least six
Bobolinks singing and saw three males together. There
were a good many Spotted & Solitary Sandpipers and
I saw five Least Sandpipers, two singly & three together.
A Green Heron was perched on a willow over the river
near the mouth of Cemetery Brook & a Bittern standing
on the edge of the water lower down. A White-bellied
Swallow has a nest in one of the willow stubs just
above the Holt & was looking out as I passed. I
also saw a pair of Black Ducks flying low over the
meadows. Red-wings were unaccountably scarce. I do
not remember seeing or hearing more than two or three.
