scenery than in me. However, he did not neglect to catch all
worms tossed to him though he was rather casual about it and
would not put himself out to retrieve any of my wild throws.
It will be seen that my reasoning was at fault, for he got
up later than the day before. Perhaps I should have reasoned that
because he had (presumably) had little to eat the day before, there
would be little waste accumulated in his system so that there
would be lacking one incentive for getting up. (Rhody, Archie and
Terry never foul the vicinity of their roosting places; also on
the present occasion R was not seen to evacuate during the few
minutes I remained with him.
R in roost 22 hrs. From the time he went to roost yesterday until he came down
10 min.!
this morning exactly 22 hours and 10 minutes elapsed!
He remained at or near his post at the top of the bank until
I called him to the fence to get a mouse at 1:30 P.M. I did not
look him up again today, but he did not come to the cage.
November 16th.
A heavy fog blanketed everything until about 1 P.M. It seem-
ed likely that Rhody might stay in his roost until the fog lift-
ed, bearing in mind also that he had been well fed.
He was in his roost at 9:45 A.M., but at my next visit, 11:30
he was not there and not in sight anywhere. I searched through the
brush calling him in an ordinary tone of voice, but no sign of
him. When I came out into the open, a backward glance showed him
following right behind me only 6 or 8 feet away, ready for worms.
At 1:30 he was still at his post and was invited to the fence
to get a mouse. He hung around for a time, then resumed his
lookout, and was not watched further during the day.
November 17th.
At sunrise this house was in full sun, but everything below
blanketed in fog, including therefore, Rhody's roost.
I deferred looking him up until 9:30. He was not in his roost
Search in the vicinity of his lookout amongst the scattered
bushes in that vicinity disclosed him about 4 feet up in a bush
and 3 feet from my elbow. He had not made a move or a sound and
finding him was virtually an accident.
I handed him one worm at a time. The branch he was sitting
on was so small that his big feet could not clasp it firmly and
he had to depend for stability upon the support of his (now) flim-
my tail. Consequently, in taking worms, he had to be very careful
not to disturb his equilibrium. He therefore reached for them
gingerly, and, instead of gulping them with a toss and a rapid for-
ward thrust of his head as is customary, he omitted both movements,
substituting for them a pointing of his bill to the vertical,
opening it momentarily and letting gravity start it in the right
direction.
In this location I could study him at reading distance. I
have once or twice suspected that the brass ring about his pupil
was interrupted where it thins out to almost a hair line in front
of the pupil, but was now able to observe that this effect is
caused by minute flecks of brown (the color of his iris) upon the
ring.
