(No 5)
  In previous years I have often known Fox Sparrows
leave their feeding grounds in the open fields and 
weed patches to seek their resting places for the night
among dense pines before sunset but this evening a
number of them lingered well into the twilight about
the seed bed in front of the cabin. All the Juncos
deserted it half an hour or more before this, according
to Gilbert who was on the spot. At 5.45 P.M. 
I came upon what appeared to be the entire flock
on Pine Ridge where they had evidently settled
themselves for the night although the sun was
still well above the horizon. They were scattered
about over an acre or more in dense, bushy
pasture pines of large growth. As I strolled about
among these trees I started bird after bird to the
number of a dozen or more. Each would flutter
noisily and utter the tsup call once or twice just
as it left its roost to seek a new one at a 
short distance. Until thus disturbed not once of them
uttered a sound or gave my any other indication of
its presence. Most of them flew from perches near the
ends of the pine branches from six to ten feet above
the ground.
Fox Sparrows go early to bed.
Juncos go still earlier.
  Still earlier in the afternoon (certainly not
later than five o'clock although I did not note the time)
I saw a perfect stream of Juncos pouring into some
scattered white pines in the berry pasture at the Farm.
At least 100 birds passed me in the course of a
few minutes, coming from the open fields in Mr.
(?) farm and disappearing among the dense
foliage of the pines. I feel very sure that they, too,
were seeking their roosts.
