Concord, Mass.
1899.
May 8
  Forenoon clear, afternoon hazy. Moderate & cool wind.
  I passed a restless night and whenever I was awake the
Swamp Sparrow that I heard when I landed at Ball's Hill
last evening, and afterwards (from 9 to 10 P.M.) as I sat writing
in the cabin, was singing [?] [at] short, regular intervals. I believe
that he sang through the entire night, which was clear and 
starlit but nevertheless rather dark. The only other Sparrow which
I have ever heard sing steadily, regularly and frequently at night
is the Henslow's.

  Chestnut-sided Warblers, 
Redstarts, Black throated Greens, Black &
white Creepers, Oven birds, Red-wings, a Grosbeak & a White-throated
Sparrow were singing near the cabin early this morning.
  I spent the forenoon at the Barrett place walking both ways
through the woods. The country was literally alive with
birds but the only species new to my list was a Blackburnian
Warbler whose wiry song I heard in some tall pines in the
Davis woods behind Bensen's. There were a good many White
throated Sparrows & I saw two Yellow-rumps. All the other
birds belonged to species which spend the summer here.

  I found a Partridge's nest with 12 fresh looking eggs in a path
of Huckleberry Bushes under a Red Pine on the north edge of the Barrett
Run about 50 yards from the drumming wall & 40 yards from the
site of the nest with 13 eggs which I photographed last year. We
were thinning out birches & Mr. Libby cut down a large one that
stood within 15 feet of the nest. As it fell the Partridge rose flying
slowly almost like a Rail. The tree fell within a yard of the nest. 
We had been talking & cutting other trees close about the spot. On
