crest raised and skin colors displayed. Arriving there, he watched closely while I fished out a mouse. He did not move an inch to get it. I put it "under his nose". He looked at everything else but that, never shifting his feet. I put the mouse back. He waited and watched. I got one of the tiny ones and offered it in the palm of my hand. He immediately advanced and gobbled it, but still waited. That meant: No big mice, but another little one. This eaten, he trotted off at once, contentedly. In the first example preening was his major concern at the time and he made a thorough job of it, not being deflected from it until it was completed to his satisfaction. Not until then did he undertake to start me off in my "pattern"--consciously or other- wise--by taking the initiative himself. In the second instance, in conforming to my pattern, he very clearly showed--to my mind--not only that he knew precisely what kind of a mouse he wanted, but that if the first one offered proved unacceptable, a substitute would be offered in all probability, as past experience had shown him. September 2nd. From about 11:30 A.M. to 2:30 P.M. Rhody kept close to the house, mostly in upper garden not far from this window. He was given a mouse about noon--a good big one--and instead of going away, hung about where I was having lunch in the cloister. When finished, I tossed him a couple of dozen worms one at a time, which he caught expertly. Still he hung around, at one time marching through the front door into the hall, out again, but still near at hand. I stepped out of the shop where I was working on a remote control for the motion picture camera and found him loitering out- side. I did not think he wanted another mouse so soon (2½ hours) but he did and followed me to the "mousoleum" uttering one plaint- ive whine. This mouse, like the preceding one, was large. September 3rd. Rhody was not seen here all day and his meat in the cage was untouched. Tired of mice? B's soft talk. When Brownie came to me for worms he was quite talkative in a gurgling, querulous sort of way. I had previously noted the presence of another thrasher about 20 yards away in the bushes and as B kept looking in that direction, no doubt the talk was intended for that bird, yet it was so low that I am sure I could not have heard it more than about half that distance. September 4th. Brownie again repeated the above behavior, again with a strange thrasher having just been seen a short time before. I looked for Rhody in his usual haunts several times during the forenoon without success, but at noon, as I passed the cage, he dropped down from a perch inside and came out to see what I was going to do about things in general. Accordingly I turned toward the shop yard, but without suggesting that he follow. He lost no time in keeping me company, even running abreast of me as I approached the gate. Here I stopped to see if he would take
