  Brilliantly clear with light N.W. wind.
  At sunrise this morning I heard the same birds
noted yesterday morning & in about the same numbers.
The crows were very loquacious cawing lustily in the
trees near the house.
  Just before breakfast I saw a Blue Jay hopping
about on the ground in a ploughed field, every now 
and then pausing to utter the bell note which he
accompanied by an abrupt bobbing motion of the head.
His brilliant coloring showed to great advantage against
the rich brown earth.
  After breakfast I walked up the road for a distance
of nearly a mile. The farming country on both sides
of the road was simply alive with birds. I have
never seen more under similar conditions at this season.
There were Robins, Blackbirds, Song Sparrows, Tree Sparrows (2 in full song)
Juncos (12 in a flock,  5 in a flock) Cow-birds, Flickers (3) & Meadow Larks, all
in full song, and two Downy Woodpeckers, one of these 
drumming. I also heard two Phoebes singing (one our bird
at the farm). Bluebirds were never for an instant
out of sight or hearing. I counted eight pairs birds 
two odd males. The Juncos were trilling but I did 
not hear their medley-singing. The Meadow Larks were
in a field just this side of the swift farm. I did
not know before that there were any in that
neighborhood. Red-shouldered Hawks were screaming almost
incessantly & I saw a female Bluebird alight in an
old Robin's nest and cuddle down in it as if about to
lay an egg her mate sitting near at hand singing the while. On
