me until he gets "good and ready". As to D, Preoccupation. This causes delayed response, as when he is intently gazing at some distant object, listening to something of special interest, sunning, or preening. He may then not respond for an interval measured in minutes. (2). Granting that Rhody has now responded with one or more of the a,b,c's and has decided to come, what does he now do? As a typical case, supposing him to be at C with no distractions observable to me, inhibiting his behavior. I am in the Clearing with the fence between us. This is a wire fence with triangular mesh. From the S.W. corner it is covered with ivy up to X. There the ivy ends. The ivy is not so thick as to prevent his seeing into the clearing almost anywhere. There is a hole under the fence at Y. He does m, that is, begins to approach, but not direct- ly. He moves to the north, that is, at right angles to the direct line between us, a few steps at a time, stopping to look and list- en, perhaps to sun his back also if not too hungry. This part of his course is to avoid the dry grass and seek the smooth course following the "Edge of the thicket" shown on the map. His pro- gress is slow, only 2 or 3 feet at a time at first, then longer as he nears the fence and faster with fewer stops. During these stops he looks and listens, but also "studies" me as if to assure himself that I am really there, have no tricks up my sleeve, am alone and there is no hostile object near me. (I am dealing with external appearances, not trying to arrive at his internal reac- tions, therefore am using the language that any casual observer would use). It should be stated here that this mode of progress, unless he is in a great hurry for some good reason, is not peculiar to this occasion. It is his usual one anywhere at all times. (Of the few birds I know intimately, his economy of energy is great- est. He is almost completely free of unessential moves). When he arrives at a point about 3 or 4 feet from the fence, he stops and watches me, often looking up into my face, as if aware that intentions may be foreshadowed there. (Like Brownie, the California thrasher). This is the effect that act makes upon one. His nearest point of approach at this moment is not necessarily opposite the point where I am standing. It is usually where he can get a good look at the ivy-free space X, for there is the place where I have generally invited him to reach through the mesh and take my offerings. At various times also, I have had him come under the fence at X. Within the past few days I have desired that he come into the clearing instead of staying outside. Consequently he is now generally confronted at this stage with a problem; it is, to go over the fence or to go up the hill further and come under it. In event of the latter decision he loses sight of me for a time, and has to approach me, when through the fence, by a path through the old-man sage where he can not keep me in view. (Though there is no evidence that he fears to do so). While "considering" this problem and also, perhaps waiting to see if I will not relent and hold the food at X where he can reach it without effort, he usually shows a reaction and often "cries". He now very clearly, nearly always, (Remember he has not been subjected to this test until very recently and I sometimes relent and hand him the food) shows marked indecision, evidenced by his
