I could hear Mrs. Scamell talking to Rhody, who was working his way home along the street. At 8:30 I saw him sail down from nest 1-38 as I was verifying N2's continued presence in her nest, and run rapidly up the bank toward the tool-house, where I found him waiting for me when I got there. He greeted me with a sonorous rattle-boo and was so impatient for action by me that he ran first to look in through a window and then came in through the door. He needed this mouse at once--not for immediate consumption--but to carry about as an offering. N2 still in nest. At 9:20 N2 was still on the nest, Neo absent; but song was heard from the N.E. and also from the N.W., the former probably by Inver in his territory and the latter positively by Neo, as I went there and found a bob-tailed thrasher running around on the ground, climbing bushes, singing. It seemed as if he and Inver were having a long-range contest; but I wonder if he knows where N2 is and is rejoicing in momentary freedom from his worries, or whether he thinks he has lost her and is looking for her. It may be that this sudden devo tion of hers to the nest has not been anticipated by him. Neo takes charge. At 9:40 it was Neo on the nest. Calls for relief. At 10:00 he called loudly with a short musical phrase. At 10:08 he called again with a longer set of phrases. There was immediate answer from some place close behind me in a short, loud, but equally richly toned phrase. Neo now began to probe be- nath his body with his bill, looked restlessly about him and sang repeatedly in full, rich tones, receiving no answer. N2 comes, but shift not made. Unprece- dented be- havior? ONE EGG. At 10:13 N2 appeared at the soft-food dish and ate for 3 min- utes as if preparing for a long stay in the nest. She then proceed- ed toward it in leisurely fashion wiping her bill as she climbed to the nest. They conversed in low tones, but to my surprise, N2 came down again, unhurriedly, and wandered off. Neo remained in the nest for a minute or two, calling. Neo answered once 30 or 40 feet away, in less musical tones. Neo now got out of the nest. I look- ed into it hastily. One egg. Neo came back, called again. No an- swer. He now dropped down to the ground, ran to the drinking dish and drank deeply. He was very thirsty--hot in the nest? He started back to the nest, but I interrupted by offering worms, which he came and took, but was anxious to resume his incubation and hastened back, carrying a worm with him. Now, if Z memory serves me (I am not going to read 1542 pages of notes to find out!) this is unprecedented thrasher behavior at this place, in that, although call for relief was answered in due course and the mate came to the nest, no shift was made, and the bird in the nest left it not only once, but twice, only to return and take up the work which its mate should normally have taken over. While I was watching these events Rhody trotted past me still carrying hopefully his precious mouse in what is probably a hopeless search for a mate. At 11 precisely a loud call: Ter-ieu', three times repeated in close succession, sounded from the thrasher nest. I went there, finding N2 on the job. Neo was scrapping in the East lot. He went farther away and sang intermittently for the next 20 minutes. N2 did not call again. At 11:25 Neo appeared at the food dish and pro- ceeded to load up as N2 had done, then went directly to the nest, refusing my offer of worms. Arriving there N2 greeted him with " silent" talk. (Open and closing her bill as if talking, but making no sound audible to human ears. This is true thrasher form).
