became diffuse and more of the conversational type. Three birds
could be distinguished.
About 10:30 Neo began to sing full song from his sanctuary,
frequently introducing the victoree phrase which he has been
neglecting lately, and a see-cret (with the s lisp ed or even omitted
at times—a phrase often used by him before, but, I think, not
recorded here earlier). When he shifted to the old oak he was joined
by N2, who thereafter followed him when he shifted from place to
place, usually beginning to scr ip as he flew off.
(It has been characteristic of thrashers here that, when a
bird calls its mate, the caller usually often leaves as soon as she
arrives).
Neo had occasionally glanced down at me, sitting 50 feet
away, and suddenly, without invitation, glided down to me, accepted
worms, then climbed the SH pine to sing where he was soon joined by
N2. He then shifted to another tree, followed by N2. Here another
joined them and, as I came in to write this note, full song had been
displaced by the lower, conversational type, everybody talking at
once.
When I went out after writing this note, two thrashers were
in the pine close to the north wall of the house, moving about,
fluting, talking, "jingling" and one of them pecking pettishly at
the branch on which it stood. Another was on the north driveway
40 feet away, and another was somewhere in the court scripp ing.
They were all concerned with each other, two being spectators. The
affair then seemed to be: two males discussing matters in the pine;
two females looking on. It was impossible to keep the identity of
the individuals separate, but two now were on the roof marching
about and talking and two were in still another pine. I turned away
in order to enter the house, go up stairs and get a close look at
the two birds on the roof from concealment—but—as I turned, there
was waiting for me. (He had been sitting in his optimum tree ever
since having eaten a piece of meat earlier). He followed me and, of
course, I had to get him a mouse. He now went to peer in at the owl
in the office and I went on to carry out my original intention.
The thrashers had now left the roof and were at separated points in
the garden (including the court).
When I came down and out, there was Rhody waiting for me
by the pool in the court. He wanted, and was given, another mouse.
When I went into the shop he peered in at me. All of this flattering
interest in my movements could only mean that he wanted still another
mouse, and so it proved. He now lost all interest in me and moved
off. (These are still the tiny mice).
By noontime thrasher sounds had ceased. (78°).
Rhody went to his No.2 at 3:45 (J), but finally went to No.1.
September 17th.
No early thrasher song was heard here at all; but about 8:30
A.M., Neo was stationed in a pine near the Scamell house exchanging
songs with another thrasher a hundred yards or so away on the
boundary of Brokenwing's territory. Another thrasher (N2?) was in
the tree with Neo. During a couple of hours absence thrashers
gathered here in the vicinity of the SH pine and there was "much
singing". (J).
Rhody ran true to present form. He slept in No.1 without
being seen in No.2 at all. He was given three small mice, one after
the other, about 3:30 P.M. and "considered" a fourth.
