1519 Sept. 12th. At 6:55 A.M. Rhody was still in his house in the roost tree. There was a low fog, but we were in the upper surface of it and the light was good. Rhody had undoubtedly been in his house for about 15 hours continuously, and he is in that portion of his yearly cycle in which his hours of rest in his night roost exceed those during which he is "up and about". I do not know when he left his roost, but he was on hand for a mouse about 9 A.M., at which time the fog had dissipated and the day promised to develop into a typical September one --as it did--with temperatures running well up into the eighties. September 13th. and 14th. This month is now running true to form. At 6:55 A.M. Rhody was not in his night roost on the 14th. and while his actual roosting time during this period was not checked, it was later than 4 P.M. Okii and Chiisai, though still moulting, become noticeably sleeker and handsomer. Chiisai's twisted rectrix now lies flat against its mates. Chiisai continues to exhibit nesting instincts, at times quite strongly; Okii almost not at all. Okii now seems more interested in affairs of the world outside the cage and is more restless, suggesting some correlation with the approaching (?) thrasher "convention season", which latter, however, gives no evidence otherwise of being at hand. Except for O and C's singing, no thrasher song is being heard at this place, but Broken-wing still visits the feeding stations. September 15th. Rhody was not in his roost at 8 A.M. At 9 A.M., while I was walking about the garden, he suddenly appeared from nowhere and began to loiter around me suggestively. When I took the first step toward the mouse abode he darted off in the lead in such a hurry that he passed out of sight beyond the trees where the path makes a reverse turn from the driveway without once looking back at me. But when I reached the turn a few moments later, I came face to face with him on his way back to meet me, presumably impatient at my slow progress. Satisfied that I was really going to fulfill my implied promise, he faced about and led the rest of the way, where he was given a mouse. No display of any kind, but prompt consumption, as has been the practice for several weeks now. He now went to his oak branch near the tool-house for a long rest: three hours. When I passed him for the dozenth time in the course of some puttering I was doing, he closed his resting period by following to the shop-yard for his second mouse of the day at about 12:15. It was now in order to seek a cooler resting place. This was found to be alongside nest No.8-37 on top of the lath house in the shade of an acacia and a pine. About 1:45 alarm notes of quail were heard to the south and he reacted to them at once, finally sailing down from the roof to investigate. As he frequently does in such instances, he proceeded directly toward the sound, ending up in this case by joining the quail at the south fence. He sat on a stump 5 or 6 feet from them
