Brownie jumps up on my knee as if by right and waits until I hand him
a worm. He even expects now, if I drop a worm, that I will pick it up
and give it to him and save him the exertion of getting it himself!
At 10:40 there were no adults at the nest, but B's feet were soon
heard on the perches in the glass house and he stepped to the rim of
the nest and immediately began inspection, tapping the bottom of the
nest near the stern of each youngster in order, I suppose, to induce
Joint feed-defecation.(?) When I attempted to feed the chicks with the spatula, he
was always too quick for me and intercepted each offering, eating it
himself. To avoid stuffing him I stopped, then tapped him on the
back with the spatula. As anticipated, he tried to throw it away.
This was repeated several times. He appeared to be only mildly annoyed,
for the last time I tapped him, he noted that there were a few
crumbs of soft-food on the stick, so instead of trying to wrench it
away from me, he picked them off delicately, and resumed his detailed
inspection and police duty.
It will be noted that, while his attitude at the nest is mild
and courteous, he is in no sense servile, but is prepared to defend
himself against unwarranted intrusions upon his dignity, without being
overawed by the superiority in size of his tormentor. At the same
time he is not so preoccupied with resenting an encroachment upon his
rights as to blind him to opportunities of extracting some recompense
from the aggressor.
12:55 (Temp.72). Neither adult at the nest, but B soon came
without food and then G carrying something small. B fed the young
up to G's arrival, then ate for himself alone, so I pushed him away
and he left. G ate nothing herself, but gave the young a good feed,
settled upon them and then stared at me fixedly, so I left.
2:20. I have been watching B's behavior at the nest for about
a half hour. Throughout all of that period, except when actually
