1580. The sun was now shining brightly, so I went to look up Rhody, leaving Neo with his delusions. Rhody was now on the bank at the orchard sunning. His tail was pretty well mussed up, so I imagine he did not seek shelter of the house until it was light enough for him to see well. He was quite ready for a mouse. About 11:30 thrasher song had shifted to the north-east and I suspected that Neo had gone to the cork-elm to exchange songs with his rival that holds forth in the back garden of the house on Estates Drive, which extends all the way through to Inverleith Terrace. I was able to see him from here in the tree and drove over there. He was singing loudly and Inver (the other bird) was answering in much more subdued tones from his garden. In a half hour all song ceased and Neo disappeared. 4:40 P.M. There has been no more thrasher song up to now. Rhody began his upward climb to his roost in the eucalyptus at 4:34. Since 10 A.M. he divided his time among three places: the bank by the orchard, the roof of the cage and the acacia near his roost. He appears to have been satisfied with the one mouse. (Cloudy, calm, 50°) At 4:48 he was in his roost. Jan. 3rd. No early thrasher song this bright and sunny morning--fog at lower levels. At 8:35A.M. Rhody was already up and sunning on his favored eucalyptus branch on the south bank. Neo discovered me while I was looking for Rhody and was re- warded with worms. The initiative was his. When I returned to the house he uttered several loud musical phrases and stopped. At 9:45, as I approached the glade, there were two thrashers there. One, Neo, came at once for worms; the other faded away, al- though not especially frightened. There had been no "talking". Tentative deductions based on foregoing ob- servations. These observations suggest: That there was no early morning song because Neo was home and the other bird was somewhere nearby, and was friendly, hence presumably a female. Consequently there was no neces- sity for defending territory, no need to announce that he was at home and looking for a mate. When I left his calls were bring the new bird back from wherever she had (inferentially) gone when I made my first appearance. At 10:10 I went back, whistled and called. Everything had been quiet in the meantime. Neo came through his passage way from the bank, eager for worms. He is still very shy; any movement of the body toward him causes instant retreat. There were no indication of the presence of another bird. When I left and turned up the driveway I was surprised to find that Neo had followed, so rewarded him. I now went down to the street to look for Rhody (not seeing him). Neo mounted to the top of a rose-bush growing on the fence and began scripping, looking in my direction. I returned (after a passing automobile had silenced him and frightened him into seclusion) and stood in the driveway. He came out soon without being called and began to peck in the ground near me, keeping an eye on me and was again rewarded. Rhody now sailed down from an ironwood tree (where I had not seen him for months) and trotted up the road behind me, pausing at one point to emit one loud rattle-boo, to the tool-house for his mouse. (10:45).
