could be induced to join him). Last but not least from my
selfish standpoint; it is a very convenient location for me!
For the next few days my problem will be: how to keep away from
it and watch only from a distance. That will be as hard as to
keep ones tongue out of the vacant space left by a recently extracted
tooth.
Of late Rhody has been giving a good deal of attention to
the interiors of the trees about this place as if hunting for a
suitable nest location, and it would now appear as if that was
really his object.
His first noted actual construction work last year was on
April first, at which time he had just acquired a mate. She was
with him at the time.
March 11th.
Rhody sang most of the forenoon in the immediate vicinity of
this place. At 8 A.M. I offered him some meat at the old oak, but
he did not want it, so clapped his wings together over his back
and sauntered away. He was seen to come to the cage during the
forenoon.
At 1 P.M. I was parked in my car in the street, about a hundred
feet from the nest, at a point commanding the nest tree and
its surroundings, as well as the nest itself. As cars are continually
passing this point and parking nearby, my presence should not
disturb the bird. Rhody, almost immediately came down from the
tree, found several twigs not more than 20 feet from it and took
them up to the nest at once. I could see him in it. This procedure
was followed several times, but was varied by taking dead twigs
from inside the tree itself. At 1:20 Rhody came out to the street,
boomed 6 or 8 times in rapid succession, ran south-west to have a
closer look at a ground-squirrel that was sitting on its haunches
at the sidewalk, seemed satisfied, turned away and preened in the
shag of a shrub until 1:26, when he decided to go to the cage (as
it proved). He was there when I got there, ate meat and then turned
his attention to the youngsters, silently but watchfully, dis-playing a little. A and T both harked at him, but T soon stopped
and went to rest in the shade indifferently. R and A continued
their interest in each other until Rhody went off to seek shade.
All birds were panting. (Temp. at cage 82). R had hardly made
himself comfortable before it became necessary for him to investigate
the activities of a flicker eating pyracantha berries two feet
from the ground and 6 feet from Rhody. The flicker fled. R next
sought a closer view of some robins in the top of an oak 50 feet
away, but abandoned the idea when the birds flew when he was half
way up. It was next in order to drink. When finished he noticed
a twig by the dish, picked it up and started in the general direction
of the nest, gathering other twigs as he proceeded toward it.
It was now 1:40 and I did not follow him. Nothing was seen of a
mate at any time. R worked entirely alone. In the 20 minute
period he made about 8 additions to the nest. I still wonder
whether he is counting on one of the youngsters and have considered
releasing one of them as an experiment.
When I went to the cage both youngsters came to the wire and
maed; to Rhody they hark.
2:20 P.M. I find that there is a straight vista through the
oaks from the cage to the nest tree and, through it, at present
Rhody can be seen up and down, down and up, hard at work. This,
including the auto stunt, is roadrunner-watching de lux. Now if
