1350. At 9:30 he was not there. At 10:30 I found him standing in front of the mirror looking up at R5. Both had their crests raised and skin-patch colors fully displayed, but otherwise showed no excitement. I went inside to get a closer look at R5's colors in order to compare with Rhody's. Rhody was in full sun and R5 in shade. This would, of course, make some difference, but, as far as I could determine, the colors did not differ substantially. Further, they were arranged in the same pattern. However, the test can not be considered conclusive. out R continued to watch R5 for 15 minutes with no change of location; then, when R5 went into the upper annex, R, unhurriedly, went to the roof for a closer view. There were no threats, displays or abrupt movements of any kind--no vocalization. When I came out of the cage and stood outside the outer one, R5 came out into the latter--another first for him. R remained on the roost, but came down (about 11) to get the mouse now offered him. He wandered off to the glade, R5 watching his departure interestedly and remaining in the outer cage (disregarding my movements). They now seemed to forget each other and fell to sunning their backs. Rhody looks larger in every way. At 12:15 R was still in the glade lying on a bed of leaves in the sun. He cooed softly once when I stood in front of him. The compliment was returned, but to this he replied with a soft rattle of the beak with, possibly, some expulsion of his breath. The effect was that of a sort of pooh, as if in contempt of my utter- ance. After one or two more attempts by me, he gave four or five resounding rattle-boos in quick succession as if to put me in my place once and for all. I did not accept the hint, but stayed tues there (6 feet in front of him). At about 3 or four minute inter- vals he gave forth a cooh-co-o-o-h, four times while I was there. This "cuckoo" was soft, sweet and low. It was not at all like his coo-song, and I do not think it was his hrhu-hroo. Certainly it did not sound the same. As near as I could get it was: Cooh Coo-oo (Put clearer together) the last coo being long drawn out, first rising in pitch and then falling. At 1:15 Rhody was still there, but his attitude toward life (and me) had changed materially, for, as soon as he saw me coming, he ma-ed plaintively and kept it up. I could look down his throat and, as far as I could see he was all "black" inside. This time I understood what he wanted and went and got it for him. At 1:45 I offered R5 a dead house mouse. He came down to the shelf upon which my hand rested, but stopped a foot away. On withdrawing my hand, he took the mouse, but dropped it. He now swung his head back and forth sidewise with widely open- ed bill as if trying to disgorge a pellet. (None has ever been found in his cage). Finally he disgorged a huge pellet, the larg- est I have seen from any road-runner. I judge 4 or 5 times as large as any rejected by Archie or Terry. I have had him in the cage 31 days, and this appears to be the accumulation of that peri- od. It must have interfered materially with his digestive process- es, and it seems probable that it had something to do with his
