and that perhaps he had been there when we were looking for him without success on the 17th. Accordingly I waited; but he did not stay there and jumped to his roost tree, entering his house at 4:28. It was noted that the interior of the house was fairly shady at that time, but would be sunny a little later. There seems to be a growing tendency for him to have his last meal (from me) earlier in the day. During this period there was no noticeable change in the young thrashers. Sept. 20th. Rhody had two good helpings of meat during the forenoon, and as I had not seen him after about 1 P.M. I looked him up at 3:45, finally finding him at 4 P.M. a few feet from the ladder tree (15') inspecting a bush. I approached him to within 4 feet. He flirt- ed his wings at something in the bush (as he does when trying to make a lizard run) and made an unsuccessful attempt to catch whatever it was. To test the theory that he ought to be hungry, since he had had no food from me for several hours (notwithstanding the next to the last sentence in yesterday's notes) I started up the sidewalk toward home. He came trotting along behind like a little dog--directly away from his roost-tree and at roosting time, be it noted--until we arrived at the "mousoleum", he taking one or two short cuts in order to keep pace with me, a distance of about 200 yards, all up hill and by a devious route. It tickled my vanity to observe that Rhody, on arrival, was also "blown" and had to keep his bill open and pant. The mouse was given short shrift. I had to go back and get my car which had been left at the curb near the roost, and, on returning here, Rhody was already on his way back to the roost tree. (On account of the uncertainty of his movements I find it a good plan, when watching for him to go to roost, to park my car nearby as a comfortable place from which to observe events, rather than to stand in the open on the sidewalk and invite the attention of the passing public). Sept. 21 to 25th., incl. During this period all birds under observation were frequently observed, but no changes in trends were seen. Okii and Chiisai continued their digging songs with no appar- ent development beyond the stage last noted, when comment was made to the effect that there was a tendency to continue this song after digging had ceased for the time being: that is, a tendency for it to merge gradually into "quarter-song". Except for the few instances noted, there has been no full song by them and, as far as I can see, there has been nothing that seems in any way a step preparatory to full song. Their slumber, digging and quarter songs--unless my recollect- ions of Brownie's are at fault--are, at least as to the first two, substantially mature in volume and quality and in the very begin- ing differed little if any from those of the adult bird. To the best of knowledge and belief they have had no tutelage whatsoever in thrasher song of these types and as far as more ad- vanced types are concerned, since Brownie was killed before they were brought here, I believe that the number of thrasher songs heard by them--except when they were in the nest--is completely negligible, insofar as concerns any probability of learning. It is true that Broken-wing was here for a time, but any full
