Thrashers. Thrashers were first heard singing about 6:45 A.M., in various directions, mostly to the west. About 10:30 I attempted to get into contact with them. One of them was approached to within 20 feet near the west window of the living room and proved to be Longbill, who has the most exaggerated length of bill of any thrasher ever seen at this place. Longbill was scrapping and uttering short musical phrases, apparently in order to keep in touch with another thrasher singing volubly further down the slope perhaps 150 yards away. This other thrasher was the one that repeats its phrases so many times and, although not seen, was thought to be Broken-wing. Rhody and hawk. I went back at 2 P.M. to see Rhody again. A hawk flushed from a tree 20 feet from me as I approached. This was 40 feet from Rhody, who showed that he had been aware of the raptor's presence. I now invited R to follow to the tool-house and he responded this time, but in unaccustomed fashion, running and flying parallel to my course until ahead of me, then waiting until I had passed him, then repeating until we reached the mousery where he keenly scanned the surroundings with displayed skin-colors, but accepted the mouse. The impression gained was that his antics were due to fear of the hawk and that he recognized the journey as hazardous, hence made it in short dashes at high speed as much under cover as possible. As hawks are bad now, it seems probable that his long stay in the acacia on the bank--not one of his accustomed haunts--may be accounted for by the presence of these birds. (It should have been recorded in connection with the above thrasher note that, shortly after their song ceased, an accipiter was circling over the area which they occupied). On the basis of Rhody's behavior, as above set forth, it was thought quite probable that he would roost in the eucalyptus this night (instead of exposing himself to the hazards of the journey to his accustomed roost). Accordingly he was kept under observation at intervals. At 2:30 he went up into the companion tree of the one in which his new house was installed. (As in the case of his regular roost tree he has, when roosting in the gum tree, also used the ad- joining tree as a "ladder"). By 3:15 (next observation) he was located in sleeping post- ure on the support of the new house. At 4 he was still there. At 5 " " " " 9:30 P.M. Rhody is still there. (Clear, calm, temperature 60°). Nov. 22nd. (Sunrise 6:57, sunset 4:54). Thrashers singing and calling close by to the west. At 8:50 A.M. Rhody was still there. (Cloudy, temp. 59½°). " 9:50 " " " " " " 60 . " 10:00 " No change. (It should have been recorded that, while he was still in the same location at 8:50, he was not in sleeping posture, but was sitting up with tail hanging down). At 10:15 no change in bird or weather; no interest in me. " 10:30 Ditto. " 11:15 " " 11:40 " , except temp. 61°, slight S.E. breeze.
