completely reversed--at least inside my property lines. What goes on
outside, I do not know. Greenie has been doing Brownie's work and
Brownie appears to be doing whatever it was that Greenie was doing
before.
Up to 12:30 Brownie had not been seen and at that time Greenie
was still taking food to No.4.
The pictures of Roll No. 8, unfortunately, were fuzzy in appear-
ance, due, presumably to the loop in the film on one side of the gate
being too small, thus interfering with the smooth passage of the film
by the gate and blurring the image.
At about 1:45, it being rather too warm in the glade, I sat on
the ground under a tree on the western margin where there was a little
breeze. Greenie soon came for worms and disclosed No.4 lying down in
a hedge about 15 feet away. After the young one was well fed, Greenie
dug a small stone out of a sloping pathway at a point about 7 feet from
me, thus making a small bench on which he stretched out and rested
for about thirty minutes by the watch. During this time he closed
his eyes frequently and evidently napped, occasionally with the tip
of his bill on the ground. This habit of dozing on the ground in
broad day-light must result in frequent tragedies, if this is a com-
mon habit of thrashers in general. All of "my" birds have done it,
and as I have noted before, the impression has been gained that they
are not noticeably more acute of hearing than human beings--or, more
specifically--than I am. Consequently it seems that they should be
easy victims for predatory animals, such, for example as domestic
cats.
At 2:40 I was wondering what had become of Brownie and whether
the thrashers would begin singing again after their domestic cares
are over. As I approached the oval lawn a thrasher undersong was heard
and Brownie was located in an oak nearby, in plain sight, as the
