in the thicket, move about from point to point, occasionally rattle-
boo, but maintain enough self-possession to preen and rest.
(Incidentally there was not seen any of the decoying behavior de-
scribed by Dawson (Birds of California).
A Point of Behavior
Common to the Thrash-
er Neo, the Road-runner
Rhody and the Plover
"Beetle".
The crippled plover, christened "Beetle" by Dr. Reyn-
olds, now recognizes me as source of food and will
come and take worms from hand.
Neo, as the notes show, comes to me for worms; but he
has not progressed so far. Numerous instances have
been cited of Rhody's beginning to look for imaginary worms on seeing
me and even of his exhibiting the "salivary reflex", supposedly.
Neo, on being called from his retreat, often pecks at invisible
objects as he approaches me. Yesterday Beetle did the same. In both
cases the bird does (or did) this immediately following an extended
period during which it had not sought for food.
These notes have shown that Rhody, Archie and Terry his two
offspring, have passed by and even walked on meat for hours without
considering eating it, only to pick it up and eat it on having their
attention drawn to it by me.
Beetle, yesterday, had refused to eat some short sections of
angle worms placed near his principal standing place, although he
had looked at them more than once. When I entered the cage and ap-
proached him and sat down, he came toward me at once, but paused first
to pick up and eat every one of the worm fragments before continuing
onward to get meal worms from me.
11:30 A.M. So far the rain is only a threat. At this time
Julio "handed" Rhody, in his new house, a mouse on the end of a pole,
and it was gratefully accepted. R had refused to come down and get it,
1:15 P.M. Still in his house. Light, cold rain just start-
ed. Southerly wind, (50°).
2:05. Rhody still in his house. Not raining and, so far the
amount fallen is only a trace.
Plover deviation from
behavior just cited.
I now went to see Beetle, the plover. I entered the
cage and sat down. When worms were shown in the palm
of the hand (meal-worms) he came at once and took them. Heretofore
it had been necessary to toss a worm or two on the ground in front
of me as a preliminary.
I now placed some angle-worms on the ground before him. He
would not touch them; but when I showed him one in the palm of my
hand, he came and took it at once, but dropped it either accidentally
or purposely, and stood there looking at my palm. He would not touch
the other worms while I was there, though he might have if they had
been cut into smaller pieces as he prefers.
Similar experience Somewhere in these notes , I believe, I have stated it as past
with other
birds:
Grosbeak,
Oriole,
Goldfinch.
experience that tamed wild-birds, in an outdoor aviary, notably
a black-headed grosbeak, a Bullock oriole and several green-backed
gold-finches, once their confidence was gained, would try any food
offered them by hand, even though that food would not be taken by
them on their own initiative; further, that these birds would leave
any food they were eating at the time and come to me to eat exactly
the same food if offered in my hand. (Curiously, the oriole proved
to be a great seed-eater--provided I cracked each seed for him indi-
vidually: a slow process which annoyed him so much that he would
peck me to make me hurry and look for tender places (webs between
fingers) to pinch. As soon as the seed was slightly cracked he would
endeavor to extract the kernel. The grosbeaks method to force me
to hurry was to call in my ear, then pinch it until I handed him a
seed. In this way he got a taste of blood and I had to prevent him
from chewing my ears thereafter).
