Concord, Mass.

May 17
  Brilliantly clear. The warmest day of the month
thus far despite the fact that a strong N. to N.W. wind
was blowing.
  The birds sang with the utmost freedom and spirit
from sunrise to late evening. Indeed there has been no
such prodigal feast of their music before this season.
Everything seemed to be singing, even the Robins and
Field Sparrows. Our Bluebird simply warbled incessantly
all day long while his mate continued to work on the
nest in the bird house over the shed.
  During my morning walk I noted only a very
few migrants. There were a male & female Black poll Warbler
in the orchard near the farm, a female Black-throated Blue
Warbler in the woods near Birch Field and two male
Magnolia Warblers singing within two rods of one
another among the dense young white pines just to
the south wood of Pulpit Rock. I had expected to find
at least one Blackburnian Warbler in the woods but
failed to do so.
  On the 14th a Great Crested Flycatcher was calling
in the orchard nearly all day for the first time
this season. I supposed at the time that the was the
bird which builds there every season but I have
not heard him since until to-day when he was
very much in evidence. About the middle of the
afternoon I heard two birds, no doubt the pair,
& finally saw them in one of the elms near
the house.
