Mrs. Dickey's colored
photograph.
(Skin patch)
I have not read the description and have had only one
hasty glance at the print, but the latter was enough to show wrong
color and location of color. Not having it before me I can not go
into detail.
(It will be noted that these criticisms are made only of works for
popular consumption).
Moult.
A rough count made today indicates that the young road-runners
moulted probably as many as a hundred feathers today and yesterday.
Moulting of the body feathers seems to be at its height.
"Approach
Reaction".
Archie has a peculiar trick when on the ground and approached
by me of squatting close to the ground, shaking his head rapidly
sidewise and saying wakh, ookh, etc. when it seems that I am about
to step on him. Sometimes he gets out of the way and sometimes
lets me step over him.
"Corner
reaction".
Neither bird, when in a corner of the cage, likes to be approached too rapidly, either by me or by its fellow. This applies also to
an unexpected approach, slow or otherwise.
An odd dusting
behavior.
Archie (Terry to a less extent) has some sort of associations
or chain of reflexes that causes him, fairly often, to pick up a
stone and then dust while holding it in his bill. This may be varied
by his laying his head on my foot and then dusting, both with and
without the stone (or sometimes the most handy object). When I sit
in a certain place in the cage it seems to stimulate in him the de-
sire to dust at my feet, although the particular spot is not the only
good dusting place.
Jealousy(?)
A great many times Archie has driven Terry away while dusting
at my feet, and then done the same thing himself, although he does
not usually object to Terry's dusting at the same spot when I am
not there. Perhaps seeing Terry dusting has merely stimulated him
to do the same thing and no jealousy is involved.
Reaction to
voices.
Entry of yesterday under this caption is somewhat negatived by
an incident which occurred later yesterday, at bedtime. A was in
bed at about 5 when, about 150 yards away, yelling youngsters
started a roller-coaster down the sidewalk. Archie bolted from his
bed like shot and there was soon a panic which lasted 15 minutes, (or
until the children could no longer be heard).
Bedtime.
Tonight is a warm night, (76 at 7 P.M., 74 at 8, 71 at 10:30).
Archie, the first to bed took Room 1--now his usual one. Terry,
perhaps on account of the warmth, took the hanging nest (Room 3)
which is less sheltered; the first time for many days.
Brownie
B slept in the dorm, although he certainly needs no shelter of
any kind tonight and I rather expected him to take the acacia.
Thrasher
reactions.
Shooting a rabbit today at the oval lawn produced typical thrasher
response, viz: B, who was singing about 25 feet from the rabbit (hen,
russet-backed thrush and tree-toad mimicry) stopped for a few moments
and then resumed his song. Roughneck (identification uncertain) came
from the other direction and inspected the dead animal curiously.
Taxation of
territorial
vigilance(?)
While B was singing there were two other thrashers sitting quietly
in the same clump of shrubbery (Perhaps Nova and Roughneck). Anyway
there was no effort made to drive them away. If both were females,
perhaps they would not have been in any case, but if males, territorial
claims have been relaxed.
