Concord, Mass.
1893 
July 19                                                                                   
  Clear with two sudden, short but heavy showers in
the afternoon. Wind N. to N.E.
  To Balls' Hill at 9.30 A.M. for the day in company
with C., E.R.S., W D. and M.M. Hayward. On the way down
saw a brown Eagle soaring over the meadows and a
Red - tailed Hawk over Holden's Hill.
  After dinner at the cabin I took most of the party
to Davis Hill & Swamp. Few birds singing, a Wood Pewee
at Davis Hill and a Pine Warbler in Bensens' knoll.
Heard a Long-billed Marsh Wren at Beaver Dam Rapid but
thus far have detected no Short-bills anywhere "down river".
  After tea I walked with M.M.H. up the Estabrook road
as far as Clark Meadow. The evening was still, rather warm
& very damp. We heard a good many birds, Robins, three
Wood Thrushes, Grass Finches, Song Sparrows, Towhees, an Indigo bird,
Maryland Yellow-throat, Yellow-winged Sparrow (near Clarks') and
Whippoorwill.
  There was an Indigo Bird singing on Balls' Hill this                                                 Indigo Birds
afternoon (the first that I ever heard there) and
another near Hunt's landing on the river bank. Thus I heard
three in all to-day. It is singular that I find so
many more about Concord at this season than in June.
Can it be that there is really an increase to the neighborhood
of the rivers from the remote fields & pastures. They are
in full song now at all hours. Can they be "second
brooded"? I have never seen any proof of it but this summer
singing is suspicious to say the least.
