about fully developed now). R went off a few feet to sun and preen; the scrapping ceased. In a few minutes he was back again. Chiisai was the only scripper this time, and then only moderately. R retired again. Same result as before. R now pulled at a rope connected with the awnings. C scripped again. I then took him on my hand and carried him to a point where he could have a good look at R. He was perfectly calm about it. (3:20 P.M.). O is still larger than C. Both fly well and are good diggers. Both have the "mane" which was noted in connection with only one other young thrasher in these notes. It should have been recorded before, as it has been present from the first. Chiisai, the "bad" bird in the nest and the more backward one at first, is the gentler bird; stands handling better ; handles worms more skilfully; accepts food more readily; pays more attention to outside happen- ings. Either one, when he finds a worm, picks up a pebble or a twig may carry it to the other, making the same adult clucking sound that Brownie did when offering food to a chick. The other will open his bill, but the object does not change ownership. They are both beginning to respond to my approaching the cage by vips and by sometimes running toward me. Rhody (now in nest 8-37: 5:30 P.M.) was not far from the cage most of the afternoon. At 3:50 he again followed to the tool-house looked at my offerings and turned away, although he cried. Twice when he approached the cage Okii flew to my shoulder. Twice I held Okii close to my ear to listen to his scrips. They are just like Brownie's --whatever they were. O could not have been much afraid of R, for he would momentarily stop his scrapping and pull at the bow of my glasses. Rhody finally came to the wire and lay down. O made himself very tall and approached him stiff-leggedly. R made no hostile movss. When he began to whine I went to the tool-house followed by him and presented him with the mouse he had killed and abandoned. He was perfectly satisfied, displayed, took it to the mirror, lay down with it near the cage and carried it to nest 8-37 about 5 P.M. Rhody left nest 8-37 at 6:20 P.M. and soon headed for the roost tree. May 5th. to 8th., incl. (Written June 9th.). During this period observations continued, but specific notes were not made. Rhody spent most of the daylight hours here, got his mouse rations, worked on nest 8-37, loafed in it, watched the young thrash- ers, and in general, ran true to form. He did not sing again, but occasionally rattle-bood for my benefit when my pace toward the tool-house was too fast or too slow or too or not enough something or other. The young thrashers dug industriously in the large cage but still do not find enough food as a result of their own efforts and still like to get a "shot" from me at intervals of an hour or so. Leaf-mould from the garden is carried in to the cage and from this they get pill- and sow-bugs, centipedes and other crawling things. Meal worms and the resulting pupae and beetles are also set at lib-
