1902.
May 29
  Clear with high, cold north-west wind.
Thermometer fell to 40 degrees last night.
  Spent the day hunting birds' nests with John Thayer
and Harriman. Drove first to the Pansy farm where
we worked over two hours beating the outer tract of
meadows occupied by the Henslow's Sparrows with
the utmost thoroughness. In the lower meadow we
started a pair of birds and in the upper one two
single birds. All four rose almost under foot and
two of them acted as if they had nests. One was
flushed twice (at intervals of several hours, the second
time late in the afternoon) with a yard of the
same spot; the other flew only three or four yards at
a time and very feebly. Once she fluttered past Thayer
so close that he nearly caught her in his hand.
We searched every inch of the ground for many yards
about each place from whence a bird rose but without
finding any signs of a nest. None of the males were
heard singing to-day. We are quite at a loss as
to whether the eggs have been laid as yet or not.
  In this same meadow we started a Savanna Sparrow.
I had a good view of it & saw the yellow head
stripe. Thayer has never found it in the breeding
season before.
Savanna & Grashopper Sparrows.
  The Yellow-winged Sparrow is evidently not
uncommon here. We flushed one in a clover field
on the Pansy Farm & heard another singing a mile
or more to the southward in an upland mowing field.
