Actions

period.
ing the nest and Brownie was on the ground beneath, but without the
worm in her bill. This worm she had "crimped" while standing on my
hand, an action which I have not seen performed except when the worm
was intended for a very young nestling that needed to have its food
treated in this way. (See earlier notes). The actions of these birds
are now resembling more and more those which have previously been
witnessed in connection with serious brood-rearing operations.
Nest finished; Thrashers loaf.
At 3 P.M. there were no thrashers in the vicinity of the nest,
nor were they in the glade. After a few minutes, calling brought
a scr[illegible]from the south-east and Brownie shortly appeared. When she
had eaten she did not pick up nesting material, but immediately went
down into the chaparral on the south bank. I went there to see what
the attraction might be, but she was merely wandering aimlessly about.
I left her and returned to the glade. In a few minutes Greenie came
for worms, picked up a fibre at my feet and then dropped it. Brownie
one
returned after several minutes, had more worm, then she and Greenie
joined forces and dug a little way behind me. This looks as if they
might consider the nest completed. This is approximately 20 days
since the first work was actually commenced at this site, although
there was aimless carrying of nesting material much earlier
B sleeps in nest.6:06. No further observations until 6 o'clock, at which time
Brownie was snug in the nest and Greenie was at his accustomed roost.
This is pretty soft for Brownie. They should build one for Greenie
also. Greenie knows all about the house, has been in it many times
now. Yet I suppose force of habit, if nothing else, will make him stick
in the other tree.
October 10th.
At 7:45 A.M. the thrashers could not be found any place. I
called repeatedly in all directions without eliciting response of any
kind. Finally top notes of thrasher song could be heard off to the
east, I should say about 250 yards from the glade, over at Robinson's
