May 17
  Cloudy; wind N.E. in forenoon, S.W. in afternoon, light
all day. Ther. 47 degrees - 63 degrees.
  In the forenoon Thayer and I walked around Ball's Hill
and through Davis's Swamp to Prescott's pines. Small birds
although still numerous were in greatly reduced numbers 
as compared with yesterday. Wilson's Black-caps and 
Carolina Warblers had however increased and there
were a great many Water Thrushes and a good many 
Blackburnians. We saw several Black polls (one female) and
a pair of Black-throated Blue Warblers at the cabin.

  In the afternoon we paddled up river to Nashawtuck
Bridge where Thayer left me to take the train for
his summer house at Dublin. On the way up we saw
a Greater Yellow-legs, (8) (2) & (1) Least Sandpipers (all
but the (1) above Flint's Bridge on the N. end of Honeysuckle
Island), about a dozen Solitary Sandpipers and a 
number of Spotted Sandpipers. Of the last named I
started a prodigious number (certainly 18 or 20) on my
way down river at evening. Just below Hurst's I came
upon a flock of 8 which I drove on before me for
half-a-mile or more. All would immediately start &
fly together in a rather close bunch. They were restless
& shy. This is an unusual experience for this season.
During the evening paddle homeward I also heard a 
Short-billed Marsh Wren in Lang's meadow & a Savanna
Sparrow just above the Holt, six Carolina Rails & one
Virginia Rail. I saw three Night Hawks & a flock of 
fully fifty Barn Swallows. There is apparently 
only one Bittern pumping on Great Meadow this spring.
