1125 The thrashers are giving little attention to their nest. February 29th. Rhody given a mouse, whichlot to the west, receiving a mouse. He hrood softly after taking it, and instead of eating it, apparently accepted it as his duty to go on tour with it. He is now, 9:41 A.M., making the rounds calling. I gave him the mouse at exactly 9:25. It had not occur- red to me that he would not eat it, otherwise I would have given him one of the light gray hybrids secured from the University. He would not be able to duplicate this mouse and it would serve as a check on his operations. (Sunny and warm, but a blanket of fog over the bay below). 9:15 A.M. Rhody appears to have disposed of the mouse; at any rate, he is calling from the roof of the Scamell house and it is not in his bill. He may, of course, have laid it down, as he often does. RR sunning. At 7:45, temp. at cage 54, roof still covered, Terry had [illegible] found a beam of sunlight and was fully opened in it. A was in under the covered portion not open. I uncovered the roof, went him inside to A; he stepped on to my hand and I raised to a high roost where there was sun, and he immediately opened up. At 10:30, temp. 71, both birds in full or partial shade. Temperature conditions are satisfactory to them and there is no need for sunning. R answers my call in kind. 11:45. Rhody, who has been silent for a long time, was found quietly preening on top of the observatory, 30 Or 40 feet up. I rattle-bood at him and he returned the compliment with the same call. No mouse visible. At the cage, temp.71, both birds in shade. They whine on my approach, with lowered heads, and Archie adds a deep hrooh, hroo Rrs sunning. At 12:55, temp. at cage 81, under oak 66, both young roadrun- ers sitting or lying in partial shade, closed. Rhody on top of lath house in partial shade, in breeze (Back to it) lying down. R selects meat instead of mouse When R came down I offered meat and a dead mouse simultaneous- ly. He took the meat unhesitatingly and ate it. He had no use for the mouse.( Too long dead?). He retired to full shade to rest some more. Next time Rhody chose the mouse. At 3:15 Rhody reappeared at the cage without his lizard. He was offered a freshly killed mouse and a piece of Hamburger at the same time. This time he took the mouse and ate it, reversing his former attitude. March 1st. Rhody was heard calling at 6:45 A.M. He was lizardless for a large part of the forenoon, but actively travelling about and calling. About 9:30 A.M. he sailed down from the roof of the Scamell house, ran steadily in the street toward, then past me, took the curve by the entrance grandly and hurried onward, disap- pearing around another curve to the south. Thinking he might have gone to investigate prospects at the Reynolds', I followed. By the time I got there he was already installed upon a chimney, di- recting his song toward Dimond Canyon and the county where he
