ing it completely through his bill, a deciduous sheath usually
floating off. No oil was used, and no feathers were removed
during this period. All parts of the body accessible to his
bill were treated. He did not use his feet.
At 11:45 he decided to come down and renew contacts with
affairs on a lower plane. First a casual glance at himself in the
mirror without display; next looking and listening at the place
in the cage where the lizards ought to have been; next laying his
chin flat upon the flag-stone in front of the mirror to determine
whether it would make a satisfactory rest while he sun-fitted.
For some reason it did not work out right, so he moved a few feet
away, found the right place, settled down, pushed a clod or two
out from under himself by sidewise thrusts of feet and composed
himself in spread-eagle fashion. This use of the feet in pushing
material aside to make a satisfactory couch is the nearest approach
to scratching in the earth seen on the part of any road-runner at
this place. It is a typical act of this bird. In performing it
the feet are never moved from front to rear as in the scratching
of the usual run of birds, but at right angles to the body. There
is no pulling--it is all pushing. Usually the bird is already lying
down and the feet can be seen only at the end of the thrust.
If we consider the arrangement of the bird's toes: two pointing
forward and two pointing rearward, it is obvious that his
feet will be better scrapers if pushed sidewise than if moved in
a fore and aft plane. Perhaps this is the reason back of this odd
performance.
A few minutes of sunning and Rhody decided to join me in the
shade, lying beneath a rhododendron; also in the shade of an oak.
The rhododendron (often called "Rhody") and the road-runner "just
naturally" don't belong in the same environment, but at this place,
through the agency of man, they seem reasonably contented in each
others company.
When I moved off at lunch time Rhody promptly followed, confident
that my course would intersect the mouse-rat zone and that
the wants of a hungry road-runner would be satisfied forthwith.
And that, of course, is the way it worked out.
Now man, who has arrogated unto himself primacy in the animal
kingdom, and who has made all the definitions, prides himself
upon the intellectual feat which he has accomplished in fitting
a few of his fellow creatures into what he calls a "pattern" from
which they have not mind enough to depart. This achievement he has
trumpeted to the world through means of communication developed
by himself and which have now taken charge of him and become es-
sential to his very existence. Yet here we have one of these
lowly creatures whom we patronize, who has, without self advertis-
ing, without artificial aids or knowledge of the work of others,
while still maintaining his physical and intellectual freedom,
within the space of a few months of modest "research", success-
fully, with no margin of error whatever, completely worked out
the pattern (insofar as it interests and concerns him) of one of
these superior creatures. This superior creature, to wit: myself,
is so incapable of deviation from this pattern, that Rhody with
absolute confidence, bases his actions upon that knowledge, and it
works, not once, but every time! And to his advantage. Surely
what brain he has gets results!
About 4:30 P.M. two of us (G.K.D.) were sitting near the cage
watching Rhody inside. He was mildly concerned about the presence
of the visitor and hesitated about coming out. I was called to
