soon discovered the police-dog lying in the middle of the street. He approached the dog within 50 feet, jerking head and tail, then made a detour around him. Passing cars caused him to retreat several times up into trees on my south bank. One of them (at 3:58) he appeared to examine as a possible roosting place, as he examined the branches above him carefully in detail. These interruptions delayed his arrival at the ladder-tree until 4:19. He again followed his usual route through the tree, but this time, took only 7 minutes to reach his roost, arriving there at 4:26. (Temp. 62, bright, fair). Sunset 5:39. October 12th. Much song by B during the morning, less during the afternoon. A large part of it was undersong. Rhody was not located in the morning, but showed up at the cage at about 1:30 P.M. where he ate all the meat at one sitting, then spent the next few minutes drinking and making feints at the magpies accompanied by rattle-boos. On the latter occasions he does not usually raise his crest, but displays hid skin-patch color to the fullest extent. Seen then a yard or two away with the sun behind ones back he is more than merely handsome, he is beautiful, with lustrous metallic reflections of blue, bronze green, old rose, purple and copper and conspicuous pattern on wings and tail of black and white with body feathers of black and tawny. His pupils are expanded and the brassy ring around them is less conspicuous than when his pupils are contracted, making his expression softer. His skin-patch is stretched tight, so that the crepe-like wrinkles are smoothed out and the red, white and blue are bright. His movements, though theatrical, are graceful and he is full of ani- mation. As Rhody had not reappeared at 3:30 I went to his roosting place, thinking that, although his meal of meat had been rather early in the afternoon, its size might have sufficed for the day. At 3:40 he was already in his "third position" in the ladder tree and at 3:50½ he landed in his roost. (Temp. at 3:55, 70 deg.; Sunset 5:38; bright, windless). I wonder if his ability to get all the food he wants, whenever he wants it, has had any effect on his daily life pattern. October 13th. For several days, now, another thrasher has occupied a pine t tree about one quarter mile south of here and sung all day. Brownie does not seem to respond and, in fact, all day his singing has been negligible. Rhody was at his present morning look-out as usual. He had his meat during the afternoon, but wanted no mice. I waited for him at the roost tree until 4 P.M., then as he did not appear, returned here to find him about ready to leave and having his second drink of water within the hour. (Referring to Dawson and others re RRs rarely drinking oftener than once in two or three days). As I had not follow up and down the hill and the bank several times I did not observe his roosting time, though it was probably after 4:30. (Temp. 72). at 4 P.M., Sunst 5:3 (In the forenoon I found mocking-birds singing at : Niles; between Niles and Decoto; Decoto; between D and Hayward at Cemetery of Holy Sepulchre; Hayward).
