territory 1562. by the bird that came to me for worms: the one left in possession of the field, supposedly Neo. The other bird went about 50 yards to the east; higher up the hill and began to sing in the back garden of a house fronting on Estates Drive. I have seen and heard a thrasher + there several times during the past few months. Probably it is his territory and Neo(?) may have encroached and was driven back toward his own, where he in turn repulsed his antagonist, or else that bird was satisfied that he had driven Neo far enough away. and retreated vol- untarily into his own territory. 1:15 P.M. Thrasher song still continues over there. Territorial be- havior? (Later: Song continued up to 5 P.M.; sunset 4:51). Rhody's rising time was not observed. Julio wanted to go down and give him a mouse, but was told that I preferred to wait and see if he would not come up here first. Rhody did come up and got his mouse. At 3:30 he was not at either of his two roosting places, but at 4:50 (very late--practically sunset time) Julio saw him go to his roost in the eucalyptus tree. Back again! As it had not rained all day, presumably he had decided that (as it was also no longer windy) till he would be taking no chances on the weather by again sleeping in the open, as the stormy period was now over for the time being. If such was his "reasoning", I doubt the infallibility of his judgment. Hawks were around all day, occasionally flying in and out of the trees. It may be, therefore, that the eucalyptus tree is still con- sidered the safest place. This recent unprecedented vacillation of his in the matter of roosting is puzzling. 12 Midnight. Well, up to 11:45 P.M. it looked as if Rhody were a better weather prophet than I; but it began to pour at that time. 12:15 A.M. I went out with a flash-light to reconnoiter, the rain having abruptly ceased. Apparently Rhody was not perturbed by it in the least, as his flaxen belly loomed up conspicuously at his chosen spot in the gum tree. (I wanted to see if he would move in the night time as he undoubtedly would have in the day time). (55°) 12:20 A.M Raining again. (This is really the 12th. Dec., but "fis- cally" it may be considered the 11th.). Dec. 12th. (Sunrise 7:15, sunset 4:51). About 5(?) A.M. the storm staged a grand pyrotechnical display, apparently its last effort for, at sunrise, the sky was practically cloudless. Nearby thrasher song was heard at about the same time. At 9:15 A.M. Rhody was still occupying his same place, now enjoying the warm sun after his trials of the night. Thrashers were still singing off to the north-east. At 10:15 Rhody was still in his roost. At 10:25 I went to locate the thrasher that could be heard sing- off to the north-west. He was seen in the top of a small pine growing in the baccharis thicket. I approached to about 100 feet, remaining inside the fence, and called. No response. Making throwing-worm gestures also proved unproductive. I took a pinch of bran from the worm-box, thinking that if I tossed it into the air, he would be at- tracted by the light colored particles, associate them with my func- tion as a commissary department (provided he knew me) and come to me. This worked on the first trial --even at that distance. He instantly dropped to the ground and threaded his way up through the baccharis to the fence, where I dropped worms to him. It was noted that a tiny feather over his left eye was displaced.
