noon, when he went to nest 8-37 and worked on it in rather desultory fashion until about 2 P.M. When next seen he was visiting the magpies, but abandoned them as soon as he saw me and tagged after me to the tool-house, got his mouse, displayed, looked for no reflecting surfaces and went down the north road. Arriving near the garage, he found a stranger (man with a motor tricycle) between him and his nest, so made a long detour and arrived at nest 8-37 at 5:10 P.M. and ate the mouse there. He remained quietly lying in the nest until 5:50, when, after a brief survey of activities of birds about the oval lawn, he started for his night roost at 6:00 P.M. While mak- ing his inspection he rattle-boed so frequently that it seemed that it should have some special significance; but unless it was in some way connected with the discovery of the other birds, I can think of no inciting cause. May 8th. Up to about 11:30 A.M. Rhody was busy at the nest, had two mice--both treated with honors--strolled about the upper garden and was altogether very domestic in his behavior. To make up for this he disappeared for the rest of the day. May 9th. not At 8:15 A.M. Rhody was in his nest 8-37, nor was he to be seen anywhere about the place. At 9 A.M. he found me using the garden hose near the cage, wiped his bill thoroughly on it, then came to me without any greet- ings whatever. He wanted no mice, but preferred to hang around doing nothing. At 9:30 he was comfortably installed on the roof of the cage, lying where he could watch the magpies. His wings are short, thick and rounded, reminding one of the wing case of beetles, and in lying down, he has the odd trait of lifting them slightly and taking great pains to see that their edges are neatly fitted together over his back. I now had to leave for the rest of the day. May 10th. Julio informs me that R was about the place most of the day, in and out of the cage, working at his nest, but, wanting neither mice nor meat. At 8:15 A.M. he was working on nest 8-37 and cried on seeing me, but wanted no food. At 9:15 he was still working. I got him a fresh supply of material so that he would not have to go so far for it. He adopted it at once. It was noted that his plumage is becoming more unkempt. This I attribute both to the progress of his moult and to the rough usage which it undergoes in working on nest 8-37, which, due to the surrounding growth's being dense, is the most difficult place for him to reach and work in of all the sites so far selected. He has surprised me by working so long on this particular nest. I expected him to start another one before this. 9:50 A.M. Still working and refusing invitations to follow to the tool-house. He has found that the support at one side of the nest is insecure and that branches overhead interfere with his work, so he is extending it toward the north. It is now long and narrow. He is all "mussed up". 10:30 A.M. Still working hard and refusing to follow to the tool house. He does not pick up twigs at random, but makes sel-
