Petree, prilly, prilly, prilly. At 12:20 he heard Dux 1 singing near the north fence and sailed down, running quickly toward the cage. I followed. He was in the acacia at the east end of the cage singing with still another set of motifs. Dux 1 was in a pine 20 feet on the other side of the fence, 50 feet from Neo also singing. I watched for his comes to come. She did, running along the ground, foraging for a time and then climbed his tree, whereupon his song ceased. Meanwhile sounds from Neo's tree at the cage indicated that N2 had followed him. (She had not scrip- ped when he left her). Her presence was checked. Neo's song ceased and he glided down into the disputed territory (?) of the Nichols garden. Dux 1 sailed down to him at once. The two comes followed. Four thrashers now inside an area of about 4 feet radius. Neo and Dux 1 advanced, confronted each other with raised bills and stiff- legged movements; the other two looked on. This appeared to be a meeting of two males from adjoining territories meeting on common ground (although I suspect that Dux 1 --or Inver(?) wants the Nichols garden for keeps. This is the first time in Convention season that the participants of the two principal performers have been identified with accuracy. (Offhand it looks as if this episode conflicts with speculation made on a previous similar occasion a few days ago-- but it may not. I now hoped to see something pretty definite; but a fool of a brown towhee, acting upon the dictates of his befuddled intellect, chose this particular time to raise a hue and cry over nothing, at least a hundred feet away. The result, to my astonishment: All four thrashers instantly dashed to cover in different directions. Ordinarily I think they would have resisted the impulse to flee, but they were probably in a state of nervous tension ready to explode on slight provocation. This ended the session. (Note how "convention" appears to be resolving itself into groups of twos). Rhody, meanwhile, was phlegmatically preening on top of the cage. At 1:30 he was still there similarly engaged. After a go at the magpies he suddenly appeared in the shop door where I was examining his latest pellet, rattle-boed with impertinent head and tail gestures and led the way to the mousery when he saw me get under way. This time he wanted two of the little ones. At 2:45 he was still in his second-choice acacia at the north fence, whence he had retired after having his mouse. Here he was resting sleepily; preening forgotten for the time being. (70°). 5 P.M. I was absent from 3 until 4:45. At the latter hour Rhody was on the way to the west lot apparently on his way to house 2. However, when I called him, he came back quickly and fol- lowed about 50 yards to the pojnt where he had to decide whether to branch off to the tool-house or go to roost. He chose the latter and his choice was No.2,in the eucalyptus tree. He seemed fearful and gazed for a long time back over his shoulder toward the north east, then hurried without pause from the first station all the way into his house. Last night, about 11:45, the horned owls were calling back and forth in what seemed the direction of Rhody's house 2, and I wondered how he was taking it. It also occurred to me at the time that, on account of the owls, which were heard here for the first time in several weeks, he would not sleep in No.2 tonight, but in No. 1. and it is still not too late for him to leave No.2 and up to the time I called him back, No.1 was probably his destination. 5:27.Well, somebody please disentangle this; west 1-4At 5:14 I found Rhody had left No.2, so proceeded toward the
