looked as if she might be making a collection for Green-eyes.
From past observations, I believe that this was her first in-
tention, but, if so, it was abandoned. Usually the first
symptom of such action consists in holding a worm in the bill
and looking toward the nest; the second is to chirp and then
start running for the nest. If no chirp is given the bird
usually eats the worm itself, but if it chirps this seems to
indicate the formation of a definite resolution to carry it
to its mate. However, this is not an absolutely invariable
procedure.
A.M.
April 17th. Rain started about 9:50. Looks like a local
shower as the sun is shining at many points about the Bay and the
are
there a clear patches in the sky. This is the ninth day of
incubation for the first egg. The birds have given continuous
attention to their duties and only one bird at a time ever is
seen away from the nest. (10:01, sun coming out). Gave
Brown-eyes "the run of the box" again. She ate all the worms
she wanted, laying one on the ground beside her, during the process,
then carrying it toward the nest. When half way there
she changed her mind and ate it herself. I am inclined to the
belief that she had just come off shift and that it was too
soon to change. 10:10--Brown-eyes digging vigorously and singing
to herself in a flower bed at the oval lawn. I look down at her
from the patio ten feet above and forty feet away and call her.
She will not come but gets quite excited about, running about,
looking up at me and throwing small clods about, in the meantime
practicing her undersong, a strain of which has puzzled me
the last two or three days. I now recognize it as the "kee, kee,
kee-kee " of the Sparrow Hawk (Desert? Sparrow Hawk-Cerchneis
sparveria phalaena (?)) very much softened, but per
observation was made it was repeated with the same bird.
