I now left for the afternoon. Julio says Rhody had another mouse at 3:30, coming in response to repeated calling from some place out of sight. He again slept in the same place in the eucalyptus tree. Another factor affecting change of roost? A possible factor bearing upon his change in roosts, which has not been suggested herein, is that, with increasing reliance upon human agency in the provision of food, it is not strange that he should shift nearer to the source of supply. Expressed in another way, it may be considered that this act is an evidence of increasing domestication. He is getting lazy! Nov. 26th. (Sunrise 7:01, sunset 4:52). Scattered, mostly distant, thrasher song and calls, early AM. Rhody frolicsome. Rhody came down from his roost at 9:30 A.M., preceded me up the driveway from the entrance and began to cut fancy capers through and around the sage patch. Then followed much bill wiping as if he had just eaten. Worms tossed to him were looked at curiously and then dropped. He would not follow to the tool-house, but was animated and friendly and inclined to frolic. Rhody casts 2 pellets. It was therefore somewhat of a surprise when, at 9:52 precisely, he shook his head and cast up a pellet, following almost immediately with another and smaller one, since his immediately preceding behavior indicated (to me) no discomfort. I thought, in fact, quite the opposite. This somewhat weakens the force of previous suggestions that the road-runner may be really ill when it disgorges pellets; but, on the other hand it may be that these rattlet-booping circuses really, at least at times, indicate internal discomfort. Appetite still good. In a half hour or so more he had eaten his meat at the cage. At 11:30 he was in the chaparral on the south bank and, on seeing me on the opposite side of the fence followed close to the wire eagerly until he could find a hole under it to come through, the growth on the fence now being so dense that it is impossible for him to force his way up and over. Rhody draws audience Again he crossed all the open spaces on the way to the tool-house at full speed. A big mouse was taken from hand and its hind legs waved from the corners of the bird's mouth for several seconds, until by a last effort, he was completely engulfed. This performance attracted a flock of bushtits, two plain titmice and a kinglet, all of whom climbed down to the lower branches of the trees overhead and scolded. A short rest and Rhody dashed at high speed across the driveway, halting instantly when reaching the cover of the bushes on the other side. At 1 P.M. he was still sitting in a bush there taking it easy. 2:45 He has remained continuously in this same bush ever since. The big mouse he had left and I could not find him, but when I was watching a thrasher in the sage patch trying to identify it, Rhody came trotting up the path and took station near me (6') where he stood for 10 or 15 minutes, until he became restless on account of a hideous din made by children, coasters and a fox terrier on the street below. He retreated toward the tool-house, but wanted no food of any kind. He wanted to go to roost and made several advances nearly to the eucalyptus tree, each time retreating on account of the noise. Finally, when the terrier somehow or other was eliminated, R made his final attempt good and reached his roost at 3:45. It must have taken considerable courage for most of the noise came from a group only about 50 feet from the tree. R and I try to identify a strange thrasher Noise frightens Rhody
