Concord, Mass.
1910.
April 7 [April 7, 1910]
  Forenoon cloudy & calm; afternoon sunny with fresh W. [West] wind
changing to N. [North] at sunset. Another summer-like day, less warm
than yesterday, however, & pleasantly cool at evening.
  A Yellow Red-poll Warbler singing near cabin at 6 A.M.
At 7 I heard a Yellow-rump and later still found three males
of the latter species flitting about in the oaks on the hillside.
Arrivals
  At 7 A.M. a Bittern pumped once (giving but one note);
just before sunset he went through the whole performance,
repeating it at the usual intervals for fifteen or twenty minutes.
This is the first time I have heard one this spring. The
bird was in the meadow directly opposite my cabin.
Bittern begins pumping.
  No Snipe were heard this morning (although I was awake
at daybreak) but at evening two drummed for half an
hour or more over the meadow across the river from the
cabin and I heard a third scarping as it rose from
Great Meadow opposite Beaver Dam Rapid.
