(553) west of the house I heard the unmistakable song of the Russet-backed thrush,below the wall, accompanied by no other bird sounds. I stopped to listen and, from the same point, there came the song ( not a call) of the Western Robin, followed by thrasher music. I finally located the singer in the top of a dense mass of hazel and black-berry below the wall, about 30 feet away under an oak. I could not recognize him positively, but thought him to be Brownie. I tried for about 5 min- utes to get him to come to me, but he was much interested in something underneath the bushes and would not leave his perch, although he pre- tended to make a violent struggle to escape from the tangle in which he sat,and come. This bluff lasted for several minutes, but I had seen it before, so went to the glade to see if B&G were there, in which case this fellow would be an outsider. Greenie was in the glade sing- ing undersong with many variations fully up to B's standard. She would not come closer than about 3 feet and seemed frightened, so I looked behind me and discovered the cause to be a large black nondescript dog that had sneaked in close behind me. After altering this situation I returned to the west and found the thrasher in the same spot, as if glued there. It was a case of the mountain and Mahomet. When I reach the bird it was, of course, Brownie, still interested in something in the tangle which I was not able to find. He was not interested in worms, but worked over toward me and sat about 5 feet from my face, facing me. Beginning with soft sounds barely audible even at that short distance, he passed through all the stages of undersong into full song of astonishing richness and power. Whenever he stopped, I talked to him and the whole performance was repeated. This lasted for about 15 minutes, when a milk wagon,roaring along the road immediately behind him while he was concentrating on his song, frightened him off over my head down into the thicket outside the fence, where he began all over again, but would not come back on call. B's full song heard 5 feet away.
