(369) While I was giving them worms at 8:15 Brownie got a worm which Greenie thought belonged to him. He tried twice to pull it out of her bill and on the second attempt was successful. Brownie, other than holding on to it rather firmly, showed no sign of disapproval either before or after the act. Greenie's sub-song and mimicry. At 9:45 I went to the glade and called,as no thrashers were present. away A thrasher, estimated to be about 100 feet answered with a succession of scrics, rapidly approaching. Greenie came in and jumped up into my hand for worms. He then lay on the ground ten feet away with his back towards me, and for 15 minutes (actual timing) sang his undersong without interruption. I could not see that it differed in any respect from Brownie's any more than her own song varies at different times. During this time he imitated the cut-cut-ca-dah-cut of the hen, the California Jay, the ya'cup, ya'cup of the flicker and also the whurroo of the same bird as it flies away. For about 10 minutes more he continued to sing, but with occasional pauses. When I left he was still at it. B and G together again.At 12:15, on going to the glade, both adults came out of the bushes at once, Greenie being first to come for a worm. By using a little strategy each got about an equal share, Brownie showing considerable for- bearance, sitting on my knee placidly with little confidential gurgles and warbles. When I left both birds were "resting", one of them lying on the ground singing in a shallow basin scooped out to give greater com- fort. Singing in this position causes the body to bob up and down and the tail to wabble. ((Hermit thrush and house wren here today. Mr. Sampson saw the former several days ago at his place.)) About 5:45 Brownie was digging around the oak west of the berry patch and not interested in worms of my offering. She went up into the branches and sat there "thinking" for a few minutes, then came down, picked up a twig, carried it up into the tree and placed where she had been sitting. It fell to the ground, but this caused her no concern.
