February 21st. Rhody was heard singing about 7:45 (Clear. warm). At 8:30 he could not be seen from the clearing. (Temp. there 60). At 9:30 he was working hard in nest 2-36 and, strangely, he would not cry when I went there. Soon he ran down the tree (not his usual method of descent) passed rapidly by me and hurried to the next house to the north, where he went to the roof and began tattle-booning, looking north. There I left him. At 11 I was at the old oak cleaning out a drinking place. R suddenly glided past my elbow and up into the lower branches. A harsh, angry sound preceded R's sudden exit to the top of a bush, followed by loud scripping from Brownie. (This place is where Brownie had his first nest and he presumably was exercising his assumed ownership rights). I did not investigate as I wanted to watch Rhody, who immediately came to me purposefully and cried. I turned toward the shop, Rhody leading most of the way and almost getting under my feet, looking back at me. I got him his mouse, which he took with ritual and carried it to the cage. Now followed intensive coting of R5 with all the appropriate "trimmings". R5 was receptive to the extent that he kept near the wire, watched R with head and tail jerking and side- stepping, curtisied and hrooed gruffly deep in his throat. Rhody was very much in earnest, but could not be satisfied with such mild response, so sought elsewhere. Over the fence to the north he went and sat on the slope near 2-36, holding the mouse and occasionally saying wooh,wooh,wooh, wo-o-o-o-oh. After 5 min- utes back to the top of the cage to show it to R5 through the wind- ow; R5 crying. No use--back to the north, five minutes wait, then up to the nest. I now turned my attention to Brownie at the old oak. Though he was singing, he came promptly for worms, then took a twig up to the anticipated nest site, following with others at irregular intervals, all taken to the same spot. 12:30. Brownie is still working at this nest. 12:35 As R5 had not taken the mouse from his can, I went in and took it to the outer cage. As expected, R5 came out and took it at once when it was laid at my feet, although he had seen it more than once in the can and is accustomed to get mice from it. At 1:25, as I passed through the orchard, a soft hroo sounded from my left rear. It was Rhody in the partial shade of a bush and I had passed him within four feet. This is an old trick of his and I have always felt that, on such occasions, he has deliberately attracted my attention to himself. I spoke to him and then passed on out of his sight. In about three minutes I again passed him, pretending not to know he was there. This time he said, wooh,wooh, weo--o-o-o-o. I stopped, spoke to him and again passed on, to return in another two or three minutes. He had, now, however, moved out into the open on top of the wall where my elbow almost brushed him as I passed, and he did not consider it necessary to call again. About 2 P.M. he came to the cage and sat on a rock by my feet watching R5, who began to pick up twigs and stones. Hearing voices to the north of the cage, he became somewhat nervous, but did not hesitate to go there and investigate. This repeats behavior pre- viously noted where he has gone to have a look at the cause of some Brownie begins nest.
