ive space just beyond which they would like to enter. However, their inhibitions prevented until one of them discovered a gap at D which the presence of the former platform (now removed) had concealed from them during their occupancy of the cage. Through this gap they went, and for an hour or so, it was the only route they used, until Archie jumped over the hedge. Even then, though they had now two methods of getting into the new territory, the the hedge remained a restraining influence all the rest of the day. This initial jump of Archie's had an interesting consequence. For the first time in his life he found himself one one side of a low bush and Terry on the other. This acted like a trigger to put into operation an instinct or a reflex (I suppose) that had not previously come into play, for he immediately acted precisely as does Rhody when he comes to the cage to see the youngsters, crouching, feinting, displaying and dodging about facing Terry, who sat calmly on Rock 1 (See p. 1003) staring at him. This was all new—seen for the first time. I half suspected that it was Rhody, somehow mysteriously getting inside the cage. Even my Filipino boy, Julio, got a "kick" out of it and said: "He is imitating Rhody!" To one who has known both of these little fel- lows since they were eggs, this little episode was a distinct event This again adds another link in the lengthening chain of evidence leading to the conclusion that Archie is a cock roadrun- ner. From the very first I have thought he was, but "he" may be a hen. Terry I have always "felt" to be a hen, but "she" may not be I am still hoping that Rhody will somehow furnish the clue. March 16th. A little before noon Rhody was on the Scamell house with a lizard scanning the landscape for prospects. Evidently he places great reliance upon the chance of seeing a roadrunner if he watch- es carefully. Some hours earlier out on the sidewalk with a stick headed directly for his nest. He seems to take no precautions whatever to conceal his operations. He brought the lizard to the cage about 1:15 in the presence of a visitor. I went to him and offered him meat, and (another "first time") he wagged his tail, apparently for my benefit, with long powerful side-sweeps, pointing his bill toward the ground with head carried far back and pivoting his body from side to side—his courting gesture. The new cage extension gives him a fine, clear view of the youngsters and a good long beat along three sides, enabling him to maintain closer contact. This was well shown on a later visit. This time he was so intent upon watching A and T that he at first ignored a piece of stout string that had caught upon both feet. As he ran about it became more securely entangled, so that he was hobbled and his stride shortened. I did not see how he could get rid of it and had visions of having to catch him and cut it off. I expected him to lose his head and become panic struck, but he did not. At last when he could tolerate it no longer, he stopped in front of me, within eight feet, and with surprising apodness and precision, attacked the problem rationally. He began on his right foot, raising it from the ground and disentangling that one first. As far as I could see he made only one mistake, and that was to pull on the end of the cord first, thus tightening it, instead of taking hold of a bight. However, he immediately changed his tactics and pulled on a loop, which, no doubt by pure
