Concord, Mass.

May 22
[May 22, 1910]

  Forenoon sunny & warm; afternoon cloudy with chill east wind. 
  No arrivals noted, no north bound birds of any kind seen or heard.
It looks as if the migration were practically ended. The woods dense with
foliage and very many of the trees, such as maples & birches, in full leaf.

Hermit Thrush singing near Berry Pasture

  About 7 o'clock this evening I hear from our farm house, faintly
but with perfect distinctness, the song of a Hermit Thrush coming from
a considerable distance towards the westward, apparently from the
young oak woods on Lawrence's land beyond our Berry Pasture.
The bird continued singing as long as I remained listening or about
five minutes. I wonder if it was the same Hermit I heard in
Birch Field a few evenings ago.

Oriole tries to steal building material from nest of Yellow Warbler

  Gilbert found a Yellow Warbler's nest this morning. It is
very conspicuously placed in the very top of a thin-foliaged snow-berry
bush just behind our house within five feet of the pantry window.
Soon after he showed it to me I heard the birds making a
loud, continuous outcry similar to that of a small bird in the clutches
of a hawk or cat, e-e-e-e-e-e-e very shrill and plaintive. Hurrying
to the window I saw the [male] Warbler flitting excitedly about the
nest & the [female] in it her wings & tail spread, her bill wide open.
Within two feet of her was a [female] Baltimore Oriole sitting motionless
regarding her with what seemed to me a cynical expression. A
moment later the Oriole fluttered to the nest and the Yellow Warbler
left it precipitately. Just as the Oriole began tearing at the
outer wall of the nest, evidently to plunder it of material to
work into her own in the elm nearby, I rapped on the
window loudly & frightened her away. Soon after this the
Warbler came back & inspected the nest carefully. It is
practically finished but empty.
