be certain. (See p 1455) 1451 1:15 P.M. Rhody continued to work earnestly on his nest until a little after 11 A.M. He then disappeared and I have just located him at the cage "spread-eagling". At 2:30 he was on top of the cage with a small lizard, showing it at one of the windows. At 3:50 he was back at work on 8-37. 4:15: Still working. (Dr. and Mrs. Grinnell are due here between 4:30 and 5 and I am hoping Rhody will stay on the job and am avoiding all moves that might be interpreted by him as invitations to come to the mousery). 4:45. Rhody has disappeared! I can't find him anywhere. (The remainder of this note written May 13th.) Dr. and Mrs.G and their son Richard arrived just a few minutes after I had given Rhody up. However, perhaps three quarters or a half hour later, when we were near the cage, Mrs. G spied him on the driveway headed for the cage. He stopped on being hailed, and dusted, then continued to the cage. I did not want him to eat the meat there, as I wanted the G's to see what he would do with a mouse (or a lizard) so I followed him into the cage and took the meat just as he was about to take it from the dish, then returned to the G's. R soon followed directly the group. When he reached us he stopped. I did not lead the way to the tool-house, as I wished now to demonstrate that he would now go on the rest of the way himself and wait for me. And that is what happened. At this moment, however, a delivery truck roared up the road and passed between R and ourselves. R. of course, sought cover. This gave me an opportunity to get the lizard from where he was "held in reserve" and a mouse. The truck now departed and R presented himself, coming from the direction of the tool-house. He was a little shy, but for the first time in his career, voluntarily approached a group standing in the open, where a woman was present. (Not quite correct: He did this 2 Or 3 minutes before!). I now placed the lizard and the mouse at my feet in the open road perhaps ten feet from the visitors. R showed a disposition to keep me in between as a buffer. Neither lizard nor mouse stirred. When R got ready to make his selection he flirted his wings (shrugged) once. I said: "That means he wants the lizard"-- a rather risky statement to hazard, yet, by precedent, such was the probability, and fortunately (for my reputation as a prophet) it was the lizard that he took. Retreating a few feet he bowed, hrooed deeply and tail-wagged vigorously. I think (as he did not retreat further for some time) he wanted to take it to the mirror but was deterred by the presence of the group in the line of ap- proach to the cage. In any event, he now continued west along the north road, stopping to bow, hroo and so forth. I thought he would take the lizard to nest 8-37, but he went past it and down into the street to the cars in front of the Scammells' and, when last seen, was headed for his roost tree. May 13th. At 8:15 R was not working, but at 9 A.M. he was very busy at 8-37. It has been recorded that he has started an extension of this toward the north (really N.E.). His whole structure now is roughly in the outline of a figure 8, as if the new portion were intended to be a complete nest in its own right, so to speak. These notes have shown that this particular nest has received his at- tention for an exceptionally long time, and that I have expected it
