The birds then disappeared. During all of this time, i.e. from 7:45 to 8:15 the birds paid not the slightest attention to me. Singing was almost constant and ranged from 3/4 to full. As far as I could see the principal singer was largely a spectator, merely following the chase. I think it was Brownie, but am by no means certain. No fighting was seen and I had no glasses. I call thrashers from Indian Gulch. At 9:30 I went to the fence along the north line and stood about 50 feet from the N.W. corner looking down over the chaparral slope into the canyon due west. I heard scrapping beyond the street and saw two thrashers appear on top of an oak yds. to the west and feet lower. I began calling at 9:35. The scrapping stopped and both birds dropped from the tree on my side. Between us was the chaparral about 6 feet high and I could just see the top of the tree in which they were seated sitting. I continued calling and moved to the west fence . In about 5 minutes there was rustling in some scrub oaks forming the southern boundary of the chaparral patch, and I caught glimpses of two thrashers about 50 feet from me and 8 to 10 feet up in the branches. They worked their way towards me with occasional loud bursts of song on the part of one of them and low calls by the other. The nearer, when about 25 feet away, flew to the top of the wire fence landing about ten feet from me. I dis- played worms and it came rapidly towards me in sidelong jumps, head pointing first east and then west at right angles to the fence, the top wire being too small for it to walk on. The wire is so small that the bird's claws make more than one complete turn around it with the claws on top of the wire, but still pointing in the normal direction. This one was Brownie. Due to the height of the fence and the sharp slope she was right in my face, too close for clear focus. She could not balance well on the wire so I gave her a finger to sit one. She talked volubly in very deep tones with throat swelling out like a large bubble. Greenie also flew to the fence, but continued his flight Enthusiastic return. B balances on small wire. B "in my face".
