Concord, Mass.
1907.
April 5
(No 2)
closely followed by the much smaller plain
grayish Bird which I feel sure was a female,
no doubt his mates.
  On my way to the farm in the afternoon
I saw about 50 Juncos feeding on the turf in
Bensen's pasture. One would not think there
could be any seeds there it is kept so closely
cropped all summer and autumn by the cows yet
the Juncos were eating something.
  When I reached the Ritchie place (about 5.15)
two flocks of Robins containing respectively 25 and
13 birds were flying into the Barrett Run from
the southward. A little later I saw another flock
arrive from the direction of Birch Field and
pitch down into the run. I have known Robins
to congregate there before to roost.

  As I was returning through Birch Field about
6 o'clock a large Cock Partridge flew from 
a poplar crowded with mature catkins. I
instantly stopped short and examining the top
of the tree closely discovered another Partridge
sitting very erect and absolutely motionless on
a slender twig. This bird, a small hen, flew
off in a direction opposite that taken by the
male when I went through the motion of
pointing a gun at her. I suppose she must
have been the mate of the other bird & I
have no doubt that both were engaged in
building before I distracted them.
