full song of the russet-backed thrush; all of its varied calls, in- cluding danger and scolding and a varied assortment of phrases strongly suggestive of other wild birds. He and Neo are about 75 feet apart and in view of each other, Neo is fairly excelling him- self and I think is catching russet-backed timbre, if not its full phrases, from the other bird. Full song gradually faded away and, at 2 P.M., Neo was found sitting concealed in the depths of the honeysuckle in his innermost retreat singing softly to himself. (76°). Rhody's moults. Rhody, meanwhile, not wanting a mouse, had helped himself to meat in the cage. His crest has large gaps in it due to the moults. Rhody in house 2 at 4:15. 4:15 P.M. Rhody has just gone up into his house No.2. It remains to be seen whether he has gone there for the night. It is bright, calm, 72°. There is nothing in the weather to cause him to retire early. He has had one mouse and two pieces of meat today. What he has caught himself I do not know. Thrashers about all day so far: principally Neo and mate; no more conventions. 5:20 P.M. Well, at 4:49 Rhody was not in house No.2. After search about the grounds I went to house No.1. There he was!?!. This offers innumerable opportunities for speculation; but I will merely note certain physical facts here: 1. The sun shines in both houses at this time of day and year. 2. It shines into No.1 until sunset, at all times of the year. 3. At this season it will be out of No.2 much earlier than for No. 1, on account of trees to the west. Later, at about the end of this month, the sun will shine in both until sunset and continue to do so until about the Vernal Equinox, when No.1 only will "see the sunset" (and consequently Rhody). 4. The west-facing bank where No. 1 is retains the heat of the sun longer after sunset and, when there is no wind, the air is warmer later in the night, than at No.2. September 5th. Thrasher song first heard at 5:40 A.M. From then on it con- tinued practically without interruption until after 9 o'clock. The morning was bright and fair. From the beginning song was right at home, with others from the distance. At 8 o'clock it was coming from all direction, two or three birds being singing here. At little later the principal song was coming from the pine south of the tool-house. At 9, reason- ably certain it was Neo, I went out; singing continued for a few minutes, ceased, then he dropped down to me for worms, N2 following, but not all the way to me. This terminated loud song here and curiously, none could be heard from afar, but there was local "talk" in which could be heard the pit-yur-kit, pit-yoorky phrases used by Brownie. Shortly all thrasher sounds ceased. (Est. temp. 68°). Rhody was found sitting in the almond tree from near which the talk came. He brightened up on seeing me, came down and beat me to the tool house, greeting me with a rattleboo on my arrival (or perhaps is was censure for being so slow). He picked up the large mouse offered, but dropped it and allowed it to run away and stood quietly waiting for me to hand out a smaller one, which I did. He ate it promptly and then retired to the lath screen to rest and, later, preen. At 10:30 (actual temp. in court 72°) no thrasher sounds what- ever, but in five or ten minutes song of several birds revived, all coming from the direction of the Robinsons' (East).
