1187 Brownie's and Nova's present nestlings number two, again duplicating Nova's previous efforts. (Later - May 21. Than are 3) The first brood of the year no longer considers this place as home, but one or other of the two, on several occasions, has come out of the bushes to the west outside the fence, on call, through, under, or over the fence, climbed a 5 or 6 foot stone wall support- ing the road and eaten worms from hand in the presence of visitors perfectly strange to them. In one instance: three visitors, one of them a restless small boy. Both still have their "manes" intact. Further in reference to the first paragraph of today's notes, there has been a change in Rhody's actions since he started nest 5-36. Up to May 6th, the notes show very clearly that he interested himself in all nests, working on them, resting in them and carrying food to them. Since May 6th., however, he has been seen to visit no nest other than No.5--with one exception. That ex- ception was one visit to No.1, when, due to the presence of visit- ors too near No.5, he was afraid to approach too closely, so went to No.1. May 16th. to 18th., incl. During this period no departure from form was observed on the part of the thrashers or the roadrunner. Rhody continued to add material to 5-36 from time to time and do the usual things. His behavior in sitting quietly in his nest for such long periods appears to be an instinctive carrying out of his part in what should be a time of incubation by both male and female. May 19th. 11:00 A.M. Rhody and Brownie as usual. A little earlier I was sitting near the oval lawn when I noticed a California Brown Towhee loitering near me for the first time this year. I then recalled that, last year, during the nesting season, a brown towhee had suddenly shown similar interest in me without my having offered inducements, and that what it wanted was worms for its brood. (I had never attempted to tame these birds' Last year the towhee had learned, presumably by observing Brownie's success with me, that I was a source of food during breeding time and acted accordingly, with success. Since that time, no brown towhee, has ever approached me until now. I do not know whether the present bird is the same individual or not, since there are so many of them resident here, but, in any case, this bird has either just learned from observation or else has remembered its last year's experience for a whole year. I really had forgotten all about it so completely that I was surprised at first by its behavior. Rhody refused mice all day, preferring meat. May 20th. At about 7 A.M. Rhody was on top of the chimney trying hard to disgorge something--as judged by A and T's actions when seen actually getting rid of an accumulation of mouse fur. He kept this up for several minutes, but owing to distance, I could not see whether he was successful. This is the first time he has been
