1669 April 28th. Rainy morning with much thrasher song. About 8 A.M., there was a lot of confused thrasher song near the oval lawn and I went out to investigate. Neo and another thrasher were engaged in combat, Neo being the aggressor at the moment. The chase came to and ivy- covered bank which I faced and there, at eye level and less than ten feet from me, Neo got the other fellow down in the ivy and "gave him plenty". The invader retreated, perhaps largely through fear of me, as he had been doing fairly well before that, although losing. To be certain that Neo's opponent was not N2 and that this was not a mating affair, I had listened for signs of her presence and had heard her singing near the glade. I went there, found her and the two youngsters. Up till about 11 A.M. this other thrasher continued to remain on the property, but a considerable distance from Neo's inner territory. At one time it was accompanied by another bird. I was unable to see whether either was banded. (Trying to identify either with Okii or Chiisai). Rhody, earlier in the morning, had been found by Julio under his roof under the old oak. Julio had asked him if he wanted a mouse and the bird had responded by leading the way to the tool house, where he was accommodated. I found him later in his house in the peppermint gum. April 29th. At 7:45 A.M. Rhody sailed down from the roof to land close to me and act very cooly; but he did not want a mouse. Thrashers had been singing S.W. of the house. I found Neo, N2 by tree 8 in the west lot. Neo came for worms and took them into the brush. There were no evidences of thrashers in the vicinity of the nest; so they appear to have moved to the west lot. 10:30 A.M. About 10 o'clock Neo again fed his young in the brush by tree 8, then came back over the fence. I went to the sage patch near his two nests to see if he was still interested in the locality. I was surprised to have a young thrasher run toward me and accept worms just as Neo does. He seems to have tamed himself. Soon he began "silent talk" directed toward the fence and it was seen that Neo had returned, as hoped. He then joined Neo. For the last day or two both thrashers appear to have forgotten about the new nest, which seemed to be complete for occupancy on the 27th. No "thinking" period has yet been observed in it. 10:45 A.M. Neo is now feeding the youngster that has stayed home with food not furnished by me. He therefore looks out for both, although they are now about 125 yards apart and N2 is with the one near tree 8. They have been out of the nest 13 days. Later in the afternoon all four thrashers appeared to be in the tree 8 area, though one of the young birds may still have been in the original nest area. Rain began to fall about 4:30 P.M. and Rhody, after having a mouse, retired for the night to his house in the eucalyptus. This seems to have been a clear instance of weather conditions (when his appetite was satisfied) inducing early retirement, and not his "incubating complex"; for the latter has been little in evidence during the past few days. His actual retirement was about 5 P.M. At that time all the thrashers, with the possible exception of one chick, appeared to be in the brush near tree 8. Neo got worms from me to feed at least one of them.
