I tossed worms to the thrashers and Neo again did all the feeding, true to present form. Further remarks addressed to Rhody in the nest brought forth soft whoo. whoo, woo-o-o-os. He came down at 6:20; had another look at the magpies and was in his house at 6:27. Nuttall sparrows and one russet-backed thrush watched his progress toward his resting place with signs of concern. The thrush followed at a safe distance making its alarm call, but finally singing its full song 20 feet from me, several times. (Incidentally this thrush sang frequently up to 7:30 P.M.). In the two days: May 7th. and 8th. we have, climatically, two days precisely alike as judged by the human senses. Note, however, how radically Rhody's behavior on these two days differed; whereas the thrashers behaved strictly according to present routine. May 9th. This day was almost completely devoted by Rhody to his new nest, 3-38. He was first seen working in it at 7:15 A.M., using lining. I tested him again on the known composite weed and the odorless one that he rejected yesterday. His first choice was the green composite. His next was of the rejected weed. Both were used in the nest. The dry composite was all used up during the day. I had it identified at the Herbarium of the University of California. It is: Gnaphalium decurrens, var. californicum, the California Ever- lasting. His roosting time was about 6:25. The thrashers varied their current programme slightly, in that the two youngsters remained at home more during the middle of the day. Neo, when present, insisted on giving the worms to them himself; but at times they did not respond readily and he had to tap them on head neck and back. May 10th. At 7:15 A.M. Rhody was in his nest 3-38, soon coming down to play with the magpies and get more lining. The young thrashers were not seen. I left at 8 A.M., to return at noon. when I returned The two youngsters were home, and came readily for worms. Neo saw what was afoot after a few minutes, and joined us. Again he insisted on doing all the feeding and, as I had the youngsters pretty well stuffed by that time, he had to resort to head tapping to get them to "open up." No chasing of the young has yet been seen. Thrasher song at low ebb. Thrasher song is now at very low ebb everywhere within hearing distance of this place and has been for several weeks. Rhody worked a little on his nest 3-38 during the after- oon (lining), played much with the magpies, loafed a lot and was found in his house-nest in the eucalyptus about 6 P.M. A flight feather from one of his wings was found today--the first found of the present moult, excepting contour feathers.
