all about, although I knew she was snooping around the vicinity,
suddenly flew up on to my hands and looked for worms.
7:35 Brownie has just been getting worms from me at the front
steps, and Julio reports that one of the young thrashers came to
the glade while he was there less than five minutes ago and jumped
up into his hands. Brownie missed this chance!
( The young quail are now being brought by their parents to
roost in the oaks about the house. The first broods were seen here
in May this year).
As I have repeatedly shown visitors, the thrashers at this
place do not seem to concern themselves about making distinctions
between persons, as long as these persons behave in the manner to
which they are accustomed. Thus they will go to anybody who offers
food, if they want food and like the kind of food offered, provided
they are not alarmed by sudden or rapid movements or movements
towards them. They will invariably retreat when one moves from a
standing position to a crouching one, unless the shift is made
extremely slowly. In fact almost any movement of the body causes them
to retreat first, even though they approach immediately afterwards.
If Brownie is sitting on one of my hands and I hold the worm box in
the other, say a foot away, and she is considering jumping over to
it, but is hesitating for some reason, if I move the hand on which
she is sitting toward the box she will usually jump either to the box
or to the ground, usually to the ground and then up to the box.
But if I do not move that hand, moving the box toward her instead,
she may wait for the box to get near enough to pick worms out of it
and remain on my hand, or she may jump to it as it approaches. It
is unsafe to generalize with any degree of positiveness as to what
these birds will do under any given set of conditions. I think they
like to be talked to and I get the impression that if one keeps
