food of any kind. Offers of mice did not tempt him. He resumed his former habit, while nest-building, of occasionally whining when spoken to. In the afternoon he loafed and preened and was content with only one mouse. Thrashers. (Neo) Neo was glimpsed only once and ran away promptly. He is still a wretched looking creature. Maybe he is ashamed of his appearance. He has not been heard to sing for days. (Since last recorded in these notes). There is still practically no thrasher song to be heard in this vicinity. Brokenbill. This bird is still here and seems to be holding his own. July 23rd. Rhody's nesting operations. Rhody continued work on his nest 5-38 during the forenoon only. It is now a fairly substantial structure in which he can lie with comfort. He did not work so fast today. Thrashers. No change. July 24th. Brokenbill sees the light. About 9 A.M. I made my first serious effort to interest Brokenbill in me as a food provider at the Oval lawn. He responded at once to a tossed worm and ate 10 of them. The ends of his broken mandibles do not meet and he had difficulty in picking up the worms. He seems to be a bird of the year, although I think his eyes have attained their adult coloration and he seems to be full grown; but he has not the detailed markings of the adult on ear covert and throat. However, as he is moulting, it is impossible to judge as to his state of development from his plumage. As yet I have not, with certainty, heard a sound from him. Rhody working on 5-38. At about this same time Rhody, who had had his breakfast- mouse, was found working on 5-38. He worked only during the forenoon, and then only a little "calking" voids in the bottom of the nest with soft material. Rhody in the cage with the magpies. In the afternoon the various compartments of the cage were thrown together, giving the magpies the run of all of them. This attracted more than the usual attention of Rhody, who swarmed all over the cage trying to get at them; so I let him in to see whether his attitude toward them would suddenly change and he turn suddenly meek as he did when I let him in with them several(?) years ago. This time he immediately attacked them and drove them all about the inner cage and feathers were seen to fly, although, as the magpies are moulting they may have been only loose feathers ready to fall anyway. Rhody rattle-boed and the magpies screamed, but the affair lasted only about 20 seconds or so and Rhody did not press matters. The magpies quickly quieted down and Rhody began exploration of the glass-covered upper annex. They all remained in the same compartment. After a few minutes Rhody again delivered another short attack and the magpies retreated precipitately into the com- partment which they usually occupy. Rhody did not follow, soon lost interest and came out. At no time, I should say, did he appear to have any serious intention of doing them severe bodily harm and, as far as could be observed, he did not discriminate between the two birds.
