To my left foot (154)
jump up on it, as she crouched for a spring--but evidently remembered that, on a previous occasion she had not been able to
stick on it because her feet slipped off. So she backed off
a bit, crouched and jumped up on to my knee, took a worm out
of the box, looked for a place on my knee on which to pound it,
decided that would not do, so took it down to the ground and
treated it there. She then jumped up again with the worm and
replaced it in the box, selecting another, which she laid on my
left
knee thigh without attempting to pound it. (She was learning!)
But that worm slipped to the ground on my left side and fell
amongst some fragments of bark, etc. and could not be seen, even
by me. She marked its general direction, however. Without at-
tempting to recover it, she selected several more worms, prepared the
went around to my left, found the lost worm and
on the ground to my right, then took them to the nest. On her
return she went around to my left side into the bushes (My right
side was toward the nest) and jumped up on to my left elbow where
it was resting on the arm of my chair, walked along my arm and
my left thigh to the box from which she took more worms for
the young. As she evidently needed a place on which to pound
them nearer to the box than the ground level, I placed
the cover of one of my seed tins on my lap, hoping that she would
most of
use it for that purpose; but on the next trip she ate\ the worms
herself, taking but one or two to the nest, where she elected to
retire for a time. Now I am willing to admit that, if there was
not intelligence shown by that bird on this occasion, then there
certainly was no intelligence anywhere in the glade with the two
of us occupying it!
At 11:00 the Russet-backed thrush was singing in the Thrasher's
glade. I put a ladder up to the nest. The parents were away.

The young birds do not have their eyes open as yet. Their skins
are black in the sense that a very dark negro is said to be black
