Concord, Mass.
1902.
Oct. 9
  Early morning cloudy & threatening; remainder of day
brilliantly clear with strong N.W. wind. Warm at noon, cool
at morning & evening.
  At 8 A.M. a Black Duck passed the cabin, flying
low over the river. About 10 A.M. Gilbert saw three
Pied-billed Greebes swimming together off Davis's Hill. They
were close in shore & although he thinks they must have 
seen him he got within ten yards of them under cover of 
the bushes.

  At evening, as twilight was passing into night, I saw
a Great Blue Heron dimly flapping lazily along the course
of the river just above Davis's Hill. A few minutes
later I heard two Night Herons quawking and still 
later the scaipus call of a flying Snipe.

  Gilbert reports an immense flock of Crows - upwards
of 200 he thinks. They were on the meadow opposite
Birch Island where they "fairly blackened the ground."
Large flock mig. Crows.
  At the farm, where I spent the day, A Solitary Vireo
was in full song in the elms near the house at 10 A.M.
and a little later a Phoebee sang well for about half-a-
minute somewhere in the rear of the barn. In the 
afternoon a Flicker shouted rather feebly twice. In 
Birch Field at sunset I heard the pink call of a Swainson's
Thrush distinctly & very near me. There were a number 
of Rusty Blackbirds in Davis's Swamp this morning &
among them at least one Crow Blackbird whose lusty
cr-aw note I heard too plainly for any mistake.
At 6 P.M. a Great Horned Owl hooted several times
in the direction of Davis's Hill.

  Titlarks are very scarce this autumn. I saw a single
bird flying over the orchard at the farm to-day.
