R's memory. Remembers lizard in place for 3 hours Mouse and mirror. Mouse to 1-36 Brownie, the second time, does not discriminate against other bird.] April 19th. I move mirror. Rhody, with mouse remembers where it should have been. Brownie calling Nova to work. B full song in nest. Mostly concerned with his accepting assistance from me in building nest in glass house. (Takes twig to 2-36!) I work in his absence. A little before 5 (I had been engaged elsewhere since last note) Rhody was again on the watch for the lizard. I gave him a live mouse. As usual, he ignored the magpies and went to the mirror with it. After a 5 or 10 minute rest, back to the mirror for a rather extensive display. At 5:20, after wandering about aimlessly, he carried it to nest 1-36 , coming down about 6 without it, heading for his night roost in the Scamell pine. Some hours after Brownie was observed with the two youngsters, he was again followed by me by them. This time he fed then fairly impartially. This suggests that Nova is leaving the job to him and may be away. Rhody was not seen often during the forenoon, although he was out in the street at 7:15 A.M. About 11 he came to the cage, got a mouse from me and began his regular ritual, including running to "show it to himself" in the mirror. However I had shifted the mirror about 10 feet, so he ran directly to the exact spot where it had been and made his display as usual, after some hesita- tion, facing the spot. This may not have any particular signific- cance, other than indicating ability to remember where it had been, because, on this occasion he had, for the first time, displayed for the magpies immediately after receiving the mouse. Also, for some reason, he was making more frequent displays than usual, any- where and everywhere. After about 10 minutes the mouse was taken to nest 1-36 as yesterday. Brownie sang a lot during the forenoon, giving the impression that he was trying to get Nova to come back from somewhere. (I had not seen her at all). Once I looked him up and found that he was singing thus while lying in his new nest. It will be recalled that Nova has always been rather independent and that in the case of one nest at least (I forget which, now, but it is in these notes) he had to travel far and repeatedly to bring her back. Rhody Intimacies Rhody had been with me in the cage, where I was taking movies of him, for about an hour, when, about 3 P.M. he suddenly ran out, picked up a twig and went to nest 2-36. In a few minutes he was back again, got another twig and carried it up into the glass house. The next one (he was getting very busy) went to 2-36. Back again in a few minutes, he went to the glass house carrying nothing. I went there and stood below it. He began to whine, so I got a ladder, placed it, got some twigs (he continued to whine) and handed him one. This he took and placed it in the "nest" (A scraggly platform mostly put there by myself). He then came down about 3 feet and investigated a place where I had thinned out some dead branchlets thinking that the space thus made might prove attractive to him. I handed him a twig there, which he pulled rather roughly from my hand--unusual behavior for him --and then took up and placed in the house. I handed him three more in succession, all of which he took gently--crying between times just like Terry--and placed carefully. He then came down, got a twig from the ground and took it to nest 2-36! While he was away I rearranged the material in the house and added a lot of stuff taken from A and T's nest in the cage. When he came back he took a twig up to the glass house, for some reason
