January 2nd. Rain in the night, strong north wind in the morning. At 9:30 Rhody was not in his roost. A cold wind was sweeping over it. (40 in court, 45 in Clearing). He was not contacted dur- ing the forenoon. By 9:30 R5 had had his first mouse, a live white one. At 11:30 I went in with another one. He came down as if to get it, but went right on by me in no special hurry to the outer cage. I stayed with him an hour. Though he was naturally afraid of me, he did not once approach panic and seemed thoroughly to understand that the wire netting was impassable, for, although he thrust his bill through it a few times, he did not once try to force his way through. He would not take the mouse, but once or twice when it was on a perch on which he was walking he pecked it as if to make it get out of his way. Sometimes he jumped over it. He frequently came back into the inner cage where I sat and sometimes stopped in front of me for a few seconds. I am inclined toward the opinion that the scraping of trees against the upper portion of the cage where he hides had something to do with his apparent boldness in my presence. I cannot see that his skin-patch is inferior to Rhody's in brightness of coloration, and if female road-runners have dull- er colors than males--I have no positive information as to this-- the indications are that he is a male. At 1:50, when I went out to the cage again, I just caught a glimpse of him jumping from the floor to his retreat. I got a surprise on finding Rhody waiting at the cage door as if wanting to get in. I suppose the birds saw each other, but there was no evidence of trouble or excitement. Rhody, in fact, as soon as I approached, forgot all about the cage(and its occupant?) and came at once for a mouse, then off to sun his back and had not returned to the cage up to 3:15. Referring to floor plan of cage p.1003. The partition DE has not been in since the extension DEFG was finished. So that cage C and this extension form one large compartment. It connects with inner cage B through doors 2 and 3 and also by a removable 3' wide by 6' high panel at the S.W. corner of cage B. This panel has been out ever since DEFG was finished. (Not shown in sketch). I now replaced it, so R5 could not go from B to C without pass- ing through the open doors 2 and 3. I sat in the seat shown near doors 3. R5 came down from his retreat in the upper portion of cage B. (It is above the shrubs shown in the sketch). He wanted to go out to C, but discovered the way was blocked by the wire- netted panel. He showed no fear at the discovery that he was, in effect, shut in the smaller space with me, did not become badly frightened and made no attempt to conceal himself, though he was looking for a way out. There is a perch 9 feet long in cage B running east and west, horizontally, about 5 feet above the ground, passing over the pool shown in sketch. I placed a mouse on this, as R5 was now using it to walk back and forth on. The mouse also paraded back and forth on it, but the bird went faster so frequently met or overtook the mouse, and would step over it. This seemed to annoy him finally as he picked him up and tossed him to the ground. Soon the bird came down to the ground in my presence (for the first time) continuing his march there and occasionally going up
