own rendition of it. I do not know whether it was mimicry or not, but
the birds have occasional opportunities of hearing this call here.
At the same time as the singing was going on frequent scolding calls
of the Vigors Bewick Wren came from the same place. This call was
heard only when the thrashers were singing and, I think came from them.
Although this wren is a resident at this place and seen "all the time"
I do not think it probable that it would scold only when the thrashers
sing. The thrasher concert lasted just 20 minutes and then ceased
abruptly.
At 7:30 I found Snooty in the glade, shy but friendly. After
giving him worms I went directly to the house and looked at the clump
of trees where the adults had been singing, as there was some scrippping
going on there and a young, fully feathered (that is, not moulting)
thrasher came out through the leaves of the upper branches followed
by an adult, neither in a hurry, but both disappeared in different
directions. I went down into the thicket quietly and heard an undersong
coming from a clump of hazel. In this clump and about ten feet from
me were three thrashers, Brownie, Greenie and the big youngster all
fully at ease with no show of hostility or fear on the part of any
on branches
of them, sitting about 3 or 4 feet from each other. They did not re-
treat, but, on the contrary, worked into positions where they could
see me better, and, in the case of Brownie, where she could take worms
from my hand. I could not identify the youngster (who left shortly
did
on his own initiative) but did not think it was Snooty at the time,
just left
whom I had 100 yards away. working his way toward the chaparral in
the opposite direction, because the interval of time seemed too short;
I could not see his "ruff" and this was a new location for him.
However, on going back to the glade, I could not find him and his
appearance at this window--just noted--shows that he is wandering
all about the property. On my way back to the house there were
two kingfishers in the trees at the tool house, a dead spotted towhee
