him a severe lecture. To heighten this illusion, Snooty then bowed
his head with bill almost touching the ground and opened and closed
his bill as if he were replying with due humility. About quarter to
six Brownie and Greenie, who had gone out of the glade a few minutes
before, suddenly returned rather excited and ran in the direction of
Snooty, all three birds disappearing in the direction of the orchard
whence loud scripping could be heard by two birds. Thinking that
they might be after Snooky, I hastened there and the scripping of one
bird was located as coming from the fig tree. I called to this bird,
and somewhat to my surprise, it came over and down to me still
calling loudly, stopping only when it reached for a worm and resuming
it immediately afterward. I administered the same treatment and it
gradually forgot all about whatever it was excited about. This bird
was [illegible] Brownie. Going back to the glade. I found no trace of
Greenie, but the youngster was there making the most persistent effort
to catch a flying moth which I have seen on the part of any thrasher.
If he had been the object of the adult birds' recent attention, he
certainly had forgotten all about it. He even climbed a tree to get
at the moth, but without success. However, when the moth made the
tactical error of coming down to the ground where the thrashers are
at home, Snooty got him. The chase lasted perhaps as long as a minute-
which is a long time for an affair of this sort. Shortly afterwards
Brownie reappeared, seeming to have no designs on her offspring.
Some time before this a young black-headed grosbeak was "record-
ing" about 20 feet from me and about 10 feet from Brownie. It was
clearly recognizable as a grosbeak song, even if I had not seen him.
dwarf crab-apple.
He was up about five feet from the ground in a bush. Brownie's atten-
tion was at once attracted by the song and her curiosity aroused. She
walked over to the tree which is very small and open in growth and
started to climb up to the grosbeak. Before she reached him he flew.
Her motive seemed to be entirely one of curiosity.
