Rhody returns to old sleeping place. 4:11 P.M. Rhody, for some obscure reason, elected to return to his old house in the oak on the west lot, arriving there at 3:57 P.M. When I saw him start in that direction at 3:15, I fol- lowed. He followed his old route, even dusting in the accustomed place just outside the side gate.(He had had a second mouse at 2:15 , as the first one was small. At the time it was anticipated that he would want another and, when I looked him up after a short absence, he greeted me with a rattle-boo and hastened to follow to the tool- house). His first wit- nessed en- counter with Red-tailed hawk. When he was about half-way through the roost tree he suddenly straightened up and looked keenly to the south, then dropped to the ground and disappeared rapidly. A Red-tailed hawk glided about 15 feet above the ladder-tree, reversed its course and now circled about the tree at an altitude of about 30 feet, making four or five complete circles of about 25 yards diameter, eyeing the ground close- ly, then sailed off to the north, not having moved a wing . He had made no attack upon Rhody, but I think that bird was the center of his interest just the same. It is the first time I have seen one so near Rhody and the first time I have seen Rhody frightened by one. I was standing at the ladder-tree at the time and the hawk was so near that I could see the individual feathers on its body. R panicky. I found Rhody had not gone far, but he was still frightened, and when two noisy aeroplanes passed overhead just as a noisy truck with a clanking load of metal turned the corner, he darted in all directions through the brush--the only time I have seen him really panicky. However, he recovered in about ten minutes and once more ascended the ladder-tree and was in his house, as far to the rear as he could get, at 3:57. I wondered if he had not regretted his decision to change his roost when he got this unexpected scare, and half expected him to go back to the eucalyptus tree. There was no meteorological reason why he should change his roost,as far as I could see. (At 4:11, calm, sunny, 53°). Neo was not again contacted during the day, but thrasher song was heard frequently off to the north-west. Jan. 4th. (Sunrise 7:26, sunset 5:03). Considerable early thrasher song, wandering about, but most- ly off to the west. At 8:30 A.M. (partly cloudy, light wind from the north, 46°) Neo was not at his location on the south bank, but there was loud thrasher song several hundred yards away down in the canyon to the west. (It may be that Neo and the bird Poni (west) are the same). I did not go down to look up Rhody. Rhody's first Spring Song of the Year 1938. At 9:35 A.M. Rhody was at his old post in the west lot. I went to the fence at the Clearing and imi- tated his coo-song. He glanced in my direction, lowered his head and favored me with his full song! Last year it was first heard on the third of January. Yesterday, the anniversary, I cooed to him, but he would not respond. I consider it remarkable that, on two successive years, he should arrive at the same physical and psychical state of being at so nearly the same calendar day. This seems all the more noteworthy in view of the undoubted fact that, however slight the change may have been, he is, this year, further advanced in domestica- ton than last; he is more closely reliant upon man-provided food and shelter. After his first song Rhody walked into the bushes and I came back to write this note, returning to the Clearing at about 10 A.M.
