1599. Jan. 21 st. Thrasher song was first heard here at 7:02 A.M. and there was a lot of song all day coming from various directions. Much of this was due to Neo moving about to sing at different locations near the bounds of what is assumed to be his territory. Thus he sang from the N.E., E., N.W., W., S.W. and perhaps from the south, besides from various stations within the grounds. As he was frequently con- tacted, it was easy to identify him as the distant singer in many cases. (By watching him come home). As an example: I was near the entrance--about 125 yards due east of the Clearing, and heard much thrasher song due west. I went to the Clearing. Two thrashers were in the top of tree 12, both singing and in amicable relationship. A third thrasher was singing far off in the canyon below. I called to the two birds (about 60 yards away). They were much engrossed in the musical competition, but after a few minutes, dropped to the ground and ran to the fence, where I gave them both worms--Neo and his mate. During the afternoon both birds were frequently contacted at their place on the south bank and, strangely Neo(who is no longer lame) would not take worms from hand. He is very selfish in the matter of wanting all the worms and will try to get all tossed to his mate, even fighting her if they arrive at the worm at about the same time. Rhody was first seen at 9 A.M. in a tree on the south bank at the clearing, where he remained for about 3 hours. (56°, clear, calm, precursor of a fine day). About noon he suddenly ran out of the bushes near where I was working in the garden and invited attention. Offers of meat were refused and again he dashed off in circuses with rattle-boys, but when he saw me head toward the tool-house, he was satisfied and trotted after me as meek as a lamb. He seems to know that he has "got my number." This was all he wanted for the day and, at 4:30 P.M., I found him already in his house. Jan. 22nd. (Sunrise 7:21, sunset 5:21). A heavy tule fog with dripping trees, lifting about 1 P.M. The first bird heard was "Xochimilco", the bantam off to the west, at 6:50 A.M. Next was Neo (probably) in the garden at 7:10. Thrasher song continued all morning from various points of the compass. Rhody was still in his bunk at 12:05 P.M. Here we have an example of what appears to be direct physical response to unfavorable weather conditions. At 1 P.M. he was at his post on the west lot, not disposed to heed my invitation. In a few minutes he went into the thicket and did not reappear. (58°, the fog now replaced by high clouds). At this time thrasher song came mostly from a southerly di- rection and I went down to investigate. I found Broken-wing and three other thrashers at the Hershey home, 200 yards (by map) from here and about 200 feet (?) lower. I could interest none of them. There was some chasing going on. A fifth thrasher could be heard in the direction of the Robinsons' and Julio says another was here when I was down there. Rhody had not appeared inside the fence, so I looked him up, finding him in tree 8. He cried plaintively and stretched his neck as far toward me as he could and I handed him a large piece of meat, which, this time, he was glad to take in lieu of a mouse.
