Concord, Mass.
(Ball's Hill.)

May 5
  Sky half-filled with rapidly scudding clouds; a violent
and at times almost icy N.W. wind; brief flurry of thinly
falling snow flakes at about 10 A.M. Ther. 36 degrees (lowest) 58 degrees
(highest). Altogether a harsh, disagreeable day for this season.
  There was a fairly full chorus of bird voices at sunrise
but as my door and window were closed I identified very 
few of them. Gilbert says a White-throated Sparrow was
singing near the cabin. Three adult Redstarts were
flitting about together when I first looked out.

singing.
  Walking around the E. end of the hill at about 7 A.M.
I found a number of small birds collected in the dense
young pines & quickly identified three species new to this
year's list viz the Chestnut-sided and the Black-throated
Green Warbler and the Oven bird hearing one of each in 
full song. There were also a Ruby-crowned Kinglet, Canada 
Nuthatch, Pine Warbler, Yellow Palm Warbler & 2 female Yellow-
rumps. A Carolina Dove, the first I have noted this season,
was cooing in the pines beyond the swamp. Numbers
of Swallows & a few Swifts were skimming over the
neighboring meadow.

  On my way to the station I heard a Grass Finch
and a Purple Finch both on the West Bedford Shore.
  At evening few birds sang but I heard a 
Bittern pumping and a Snipe scaiping in 
the direction of Great Meadow.
  Just as the sun set a great number of 
Red-wings collected together somewhere in the meadows
were singing in medley.The general effect was
strikingly suggestive of the honking of Geese. The
birds were at a considerable distance.
