prevented by the fence, which, I suppose, he assumed to have a roof like the cage. (The fence is a wire one with triangular mesh). Since T knows all about climbing up on me, I went to the fence, although there are plenty of low acacias along it which R uses in going over. T understood this and used me as a ladder, but did not go over as R was not in sight. He was in the nest. Noon. T then went into the cage and the next thing I knew he was in here. 1:35 He is still here or hereabout, making free of all household facilities. At lunch time in the cloister he would not go more than 25 feet from me, coming up on the table, etc. Later he went up stairs and out on to the roof of the one storied portion of the house. When I went up and leaned over the parapet of a porch to watch him, he came and lay down on my back. I believe, now, that T is a female, with little doubt. The status of Archie is less certain--I do not know. 3:45 Terry has been in the inner cage (voluntarily) since 5 P.M. Rhody is, right now, investigating both the glass house in the dorm and the platform I prepared for him under Brownie's roof in the same tree. T has been calling puck, puck.....often and is restless. Rhody has, once or twice, been upon the point of entering, but has changed his mind. (The entrance, since the ex- tension, is somewhat more complicated than the one he knew). There are women and children in the vicinity of nest 2-36 and I cherish the mean hope that Rhody will conclude that that location is untenable. At the moment it seems to be a contest of wills between R and T, each wanting his nest adopted. Search for Archie over the area of the lot to the west failed to show any sign of him. He has not been seen since he entered the brush there. Food and water have been put out for him at a place where he is likely to go. 7:10 P.M. Another search about 5:30 did not locate him. Rhody has shifted his roost back to the Scamells' pine; he went up the tree at 6:34 (Mrs.S.). Sunset 6:37. This is late for him. Terry entered the cage again at 3 P.M. After 2 hours he showed no intention of coming out again, though Rhody solicited. Unusual for him--he spent all of his time inside the inner com- partment, restlessly moving about. (Missing Archie, or trying to attract Rhody?). He was shut in for the night. April 7th. At 7 A.M. I went to the cage. Julio had already opened the door and Terry was out someplace. However, he saw me and whined, enabling me to locate him and, as it happened, Rhody also, who was with him. Their attitudes were purely platonic. Terry, on invitation, jumped to my shoulder and rode around with me for a short time. Both he and Rhody then sunned their backs and T retired to the cage where he puck-pucked and hrooded. (Trying to get Rhody to go in ?). Meanwhile the wren-titmouse feud which has been of long stand- ing here, broke out in the lath house nearby, over the wren's house. Rhody went in to "arbitrate", but soon gave up. At 7:30, when I left, the situation was: Terry in cage; Rhody outside; the feud continuing actively with four birds engaged 9:00. Rhody spent the time from 7:30 to 8:30 on the observ- atory roof. He then flew down to my feet, thence to the cage, in which Terry had remained all the time, in the inner compartment, moving about restlessly and occasionally making one or another of his calls. Rhody displayed a little at various places for T's benefit, but would not go into the cage. The most T would do was to come out into the new extension for a few seconds and then
