1634 At 2:30 P.M. Neo was still working, though not very fast, at the same place. Curiously, wrentits and one Bewick's wren seemed to be attracted by what was going on and climbed in and about the very place where Neo was placing his twigs. Neo soon came out to me to get worms. N2 was there also. At 2:45 Rhody came running by with a billful of weed stalks that he had found himself and placed them in his nest. He is spend- ing most of his time inside. At 3:45 he was still working, but had been carrying only about one load each half hour, still using the weed. At 3:45 Neo was still at work, but in leisurely fashion. He again came for worms without call. I could not see whether N2 was there or not: the growth is so dense. At a little after 4 o'clock Neo was sitting quietly in his "nest", which at present is little more than a void in the tangle of honeysuckle, the interior stalks of which are leafless and of the same general coloration as the twigs of the nest. Consequently there is little to distinguish them. Rhody was now on tour someplace with a mouse given him by Julio, and no further observations were made this day. Mar. 3rd. Rain again fell during the night, although not very much, and it was threatening all day; a trace fell. Rhody worked but little on his nest and had two mice. The thrashers also had a day off, but Neo was seen to carry material to his nesting site a few times. Altogether it was not a day stimulative to the activities of birds. Neo sang to the east, north-east, north-west and west and Brokenwing sang often in his area. Mar. 4th. (Sunrise 6:39, sunset 6:06). (Papers are filled with stories of flood conditions in and around Los Angeles, where over 6 inches of rain are said to have fallen in 24 hours). At 7:40A.M., clear, chilly (46° in court and clearing) Rhody was: at his post on the west lot, sunning and refusing to sing, also not interested in food. A little later he was at his nest and a rough test was made of his discrimination in selection of nest mater- ial. It has been shown that, at present, he seems to favor a cer- tain weed; so I gathered stalks of this weed, stalks of golden-rod in about the same physical condition and other material of like nature and resembling it in appearance somewhat, and placed it near his take-off point. It was found that he would pick out the weed in preference to anything else. At 8:40 he was given a mouse with the present usual result. It was carried until 10:15, eaten and then work was resumed on the nest in casual fashion. In the meantime Neo had returned from somewhere or other and had resumed work at the site favored at present. Later he was join-
