August 4th. to 6th., incl.
During this period there was no departure of consequence
from present routine either on the part of Rhody or the thrashers.
The Convention of Thrashers has not yet materialized as
observed in 1934 and 1934. Brownie sings full song at irregular
intervals, and the same may be said for sub-song. The latter is
now, at times, of long duration: an hour or more continuously.
Rhody continues to favor his resting places in the cage and
the same acacia.
On the 6th. it looked as if he might resume his nesting work,
for a few moments at least. The impulse came to him, but faded
out. He had been resting quietly in the cage for an hour or more
and, upon coming out, performed his ridiculous series of loops,
spirals and other complex curves through the bushes to the accom-
paniment of beak-rattlings and rattle-boos apropos of nothing with-
in the range of my senses, then devoted himself to the collection
of a large sheaf of pine-needles. This he took to the mirror
for inspiration; but there, after pressing it against the glass
once, it was dropped in a casual sort of way and he turned to
sunning himself in the spread-eagle pose.
A little later he was invited to the shop for a young rat.
He picked it up without enthusiasm and dropped it twice, then
turned to wander off after waiting for further developments.
When I got a mouse for him--also white--and practically the same
size as the rat, he came back at once and gobbled it without cere-
mony. There seems to be something besides color to influence his
selection.
About 4:30 P.M. a visitor (H.L.E.) and I were sitting in the
shade of No.5 nest-tree watching him lying on the ground about 20
feet away, also in the shade, at peace with the world. After a
half hour or so he got up and approached us along a path, but
suddenly dashed past us with incredible speed, looking more like
a line in space than a bird, and disappeared for the rest of the
day. The cause: three boys approaching the fence from the north,
not at all noisily.
August 7th.
When offered the same rat today he swallowed it without hes-
itation, alive and kicking. His throat and shoulder feathers
continued to move about for several seconds.
2:30 P.M. At a shade temperature of 83 degrees, Rhody sits
in the shade with lifted wings, while Brownie sings under-song in
the glade.
At about 7 P.M. Rhody was not in any of his known night
quarters. I learned from Mrs. Scamell that he had, a few days
ago, entered Mrs. O'Neill's bed-room early in the morning while
that lady was still in bed. Since there is an acacia tree (Acacia
melanoxylon) close to the west wall of the O'Neill house (275 yards
due south of here across a small valley) and the tree would seem
to offer all the requirements of a road-runner roost--including
the unobstructed western outlet and the landing field with protection
from the rear--I went over to investigate. It seemed probable
that he might have been using the tree as a roost and discovered
an open window nearby that required investigation.
