occupied last night, that is within 2 or 3 inches of the same place.
Its head was not under its wing and it did not move while I was looking
at it. It is perhaps somewhat less than 10 feet above the ground .
I could not see evidence of the other one's perching near. I shall have
to locate the tree it is in by watching where it goes when it has finish-
ed feeding for the day. I suspect that it is in a tree about 30 feet east
of this one. This bird I think is Brownie.(I.e. the one just located).
Sept. 13th.
I went to the glade at 8:30 A.M. There were no thrashers in
sight, but after a few calls I was answered by a scrip from the chapar-
ral outside the fence. Soon this was taken up by another bird and
both thrashers came running to me for the morning worm, though I had
noted in passing the oval lawn that, possibly due to my tardiness, they
had been busy on their own accounts. Brownie's talk at this meeting
consisted mostly of a soft woor-roo followed by a couple of infinitesimal
inarticulate sounds. In order that Greenie might get his share, I offered
worms with both hands. Greenie went off 10 feet to dig and when he got
a hole well started, Brownie ran over to appropriate it. Greenie
crouched down with wide open bill, just like a youngster and backed away,
but said nothing, out loud at least, as Brownie took his excavation and
turned her back on him. Greenie bowed his head toward the ground,
opened and closed his bill exactly as if talking to himself pettishly,
made one peevish snap at the tip of Brownie's tail and came towards me.
It is exactly what I would have felt like doing myself under similar
circumstances. I have no doubt but that if one knew the thrasher
language and understood bill-reading, he would have found that Greenie
was cursing Brownie for her cheek and himself for his timidity--but
silently so as to involve no risk of retaliation. The snap at her tail
was not a serious effort either, just a gesture. Brownie probably knew
nothing about it; anyhow she ignored it.
