recognition of me by sight. (Or rather, seeing me passing by, was the trigger that set off the action). He continued his pathetic, two-toned whine for several minutes as I talked to him, then came down and followed to the tool-house. Full ritual was accorded the mouse; and it was taken to his house and not nest 3-38. He did not sing there, merely woo-h-wooing. Neo now has a long tail and sings again near the fig tree. Investigation disclosed a long-tailed thrasher in a ceanothus and it proved to be Neo, rehabilitated as to tail but, otherwise far shabbier than ever. The fact that this new tail was a surprise to me is an indication of how well he has managed to avoid showing himself in the last several weeks and of his increasing shyness during that period. Now that he has come for worms again, perhaps he will abandon his previous anti-social attitude. Following Rhody in one of his excursions abroad. What he did during 1½ hours absence. About 9:45 Rhody was at the cage playing with the magpies. He came out on seeing me, noticed a loose tuft of his favored nest lining-California Everlasting-picked it up and considered taking it to nest 3-38, but changed his mind, dropped it and climbed a low acacia (Acacia latifolia) 20 feet from the cage, attracted by the evolutions of a pair of brown towhees who have a nest there. These birds placed themselves suddenly in front of him as if inviting attack, but he paid no attention to them or their nest and looked for a nesting site for himself in the same tree. He found a good "prospect" and worked for 5 minutes trying to clear away interfering twigs, gave it up and went over the fence to the north. As these notes show, he has, in the last day or two, renewed these excursions abroad (or at least has "made himself scarce" in the vicinity of his house for several hours during the day). I decided to follow him for a time. He strolled in leisurely fashion toward the north-east, making about 3 to 6 feet at a time and then stopping to preen,"look and listen" and examine the ground at his feet. He was in no hurry and seemed to have no definite objective. He inspected the grounds of two houses near the N.E. corner of this place and then decided to go across Estates Drive toward Dimond Canyon. He crossed the street but did not like the automobile traffic, so returned to the house on the corner of Estates Drive and Inverlieth Terrace and went to the front door. Nothing developing of interest there, he went north across the street and examined a loose stone wall for lizards for a few minutes, then climbed it and sat preening and looking off over the lower country to the west from the top of a pile of rubbish. An oak nearby next commanded his attention and he took a twig up into it and looked for a place to put it. However, the tree afforded no favorable nest site and he sailed down 50 yards to the west to cavort around a young Liquidambar tree (just planted) in the top of which a hummingbird sat. This bird buzzed over him and made swoops down at him, Rhody making impertinent gestures of head and tail, but soon tiring of this entertainment, he flew up to the roof of the Nichols house at 10:15, there to preen and sun his back, having accomplished nothing of a constructive nature at all. In this time he had covered perhaps 400 yards of space and was still within 75 yards of his starting point. I left him still on the roof. He was not seen home again until 6:05 P.M. and I believe was away all that time. I saw him coming back from the north at that time. He entered the cage, brought out a piece of meste, picked a few crumbs off it, abandoned it, then went to play with the magpies. He wanted no mouse.
