August 26th.
The day opened with thrasher song, which again concentrated
into continuous song near Neo's nests. For a time it seemed as if
yesterday's experience would be repeated and Neo remain without
visitors; but about 9 A.M. things began to warm up and, until a little
after noon, we were treated to the most enthusiastic chorus of thrashers
ever heard at this place, so far as my recollections serve.
It is impossible to do it ample justice. The place was "full"
of thrashers. I do not know how many there were, but I could easily
place four singing at a time, and others moving about on the ground
and in the trees in almost any direction I looked. There seemed to
be no conflict among them at all. With glasses I could see now bands
on any of them, nor was a broken bill to be seen. About 9:45 I concentrated upon one bird, it was all so confusing. This one sat
across the road from the old oak and sang so much that he did not
bother to close his bill at all during pauses. He kept his tongue
retracted as if that position insured more resonant song. He was
a very fine singer, versatile and rich, in full plumage except that
some of his rectrices were not fully grown. His eyes were adult in
color. After about 20 minutes he spied a thrasher in the sage patch
and sailed down to investigate. There was a little dodging and side-
stepping, but no real pursuit or attack. This lasted a few seconds.
Both birds remained in or near the sage. I made a back-handed worm-
tossing gesture (without a worm) when I thought this singer was
looking at me. He responded at once, ran toward me and picked up
the worms. When he had had enough he and the other thrasher went
off into the orchard. Song was now heard from a small oak at the
oval lawn. I went there and stood 20 feet from this bird. Another
approached from the east and sat in the pine 40 feet away, also
singing. Another came from the north, sat in a pine north of the
house and struck up and independent aria. They were all good. It
was impossible to distinguish with certainty any one phrase which
they all had in common; but the second thrasher to arrive seemed to
pick up, after a short time, a singularly rapid and odd utterance
of the first bird which possessed a complex rhythm. There was
nothing to identify the first bird with the one I had been concentrating upon, either as to song or appearance. But, after a half
hour of this, he dropped to the ground and another tossed worm
brought him to my feet, so I suppose he was the same bird.
(In the meantime Rhody had joined us and sat nearby pretending
to listen and preen, but really waiting for signs of my "loosening
up" on the mouse situation. He was accommodated). Wrentits had
escorted him to the concert).
Song now shifted to the oak in the middle of the court. Four
birds were present. The last to arrive had a rough neck and said
victoree, but he made no attempt to justify the assertion. I suppose
he was Neo. All now quieted down and I left for an hour.
At 11:40 the affair was in full swing again in the pines
along the north side of the house. One came down and began to walk
about stiff-leggedly with bill pointing upward. Three others followed.
This attitude was more or less that of all of them. They all
talked in low tones and walked about 15 to 40 feet from me in plain
sight. There was no skirmishing. They separated into two pairs
(perhaps mates) and went off gradually in this formation, in oppo-
site directions, about 12:20. As developed later, this ended the
day's group action at this place, but occasional individual song was
heard from Neo's nest area.
These affairs often attract other birds, notably hummingbirds,
but also jays, wrentits of course, brown towhees, wrens, bushtits and
Rhody. Also, when the focal point was in the court today, a thrush
climbed the tree to investigate (species unidentified).
