Experiment with B.
At 9:45 Brownie was still at the glade and Nova in one of
the low trees forming it. B was given all the worms he wanted
in the expectation that he would either go up the old oak and
sing or else go to the nest. I went off to find Rhody and give
B time to make up his mind what to do.
Rhody
Rhody was not in his roost at 9:50. Mrs. Scamell called him
and he poked his head up out of the bushes in his usual morning
location west of my place and north across the street from the S
Scamell's. He stood on the bank facing us and I went over and
tossed worms up to him.
Outcome of experiment is:
B in nest.
In the meantime B had not sung again, but was found in the nest
at 10:10.
At 10:45 he was still there, singing softly at intervals. This
song was strongly reminiscent of the first immature attempts of
the young thrasher; more than of B's own quarter song.
His quarter song earlier in the glade--I forgot to record at
the time-- was made up almost entirely of recognisable full-song
phrases.
Influence of food.
This incident again suggests the strong influence which an
ample food supply may have upon the normal behavior of these
birds.

(Characteristics)
of captive.
This little fellow in the cage with the young mocking-
bird has now become sybaritic in his habits, spending hours at a
time lying or standing in his nest in the top of the pyracantha
bush. (P. Yumanensis). He is able to fly up into it directly
at an angle of about 45 degrees. Its height from his take-off is
about 5 feet. He also stands on top of the bush, but must
occupy a place where there is at least one fork as he is unable
to clasp a branch with his toes. When trying to move about on or
in the bush, he is, for that reason, extremely awkward and unsteady
and subject to falls. This is all the more noticeable because of
