1484 and were at a point on the drive-way nearest the thrush nest, he darted into the bushes. I thought the fledglings might be the attraction, but he came out with a large twig, forgot about mice and hurried back to 8-37 with it. He had evidently been working more on it than I had suspected, for he had again "blown" away all the leaves and dust from his landing place in the road in a roughly circular area about 5 feet in diameter, and the hard surface thus exposed was covered with fresh claw marks. I gather a new supply of material for him and he began at once to use it diligently with apparently as much enthusiasm as if this were a suddenly discovered new location. By 10:45 he was back near the cage and promptly accepted an invitation to the shop-yard for a mouse. This was treated with ritual and eventually taken to nest 8-37 and there eaten after hesitating uncertainly at each point where paths branched off. On the way he visited two windows at different points in order to exhibit the mouse at them. In a half hour he was again back loafing in the vicinity of the cage, paying no attention to any of its occupants. During the rest of the day he was present most of the time: preening, lying in the shade near the loquat and, in general, taking easy. Meat again meets with favor, and his dish had to be filled twice. Also, at about 6 P.M., he was ready for another mouse, which was treated with honors. At present most mice are so treated, reversing recent behavior. He was not seen to visit 9-37; 8-37 seems to have been restored to the first place in his favor. Okii and Chiisai were both strong and active, the latter now more frequently resorting to Okii's specialty of exploring my topography from crown of head to heels. Both seem to consider that when I move to another spot, my feet should immediately be dug about. If I stand long enough in one place they will often dig entirely around the periphery of one shoe and make a sort of rough, bas relief of a foot-print. Both are intensely interested in the garden loam and leaf-mould carried into the cage. I am usually able to find three or four centipedes to put in it. Of these they are very fond. If I stir the pile with a trowel they keep as close to the trowel as possible or even climb upon it in order to miss nothing. Both are sure death to yellow-jackets; although Chiisai fears them instinctively, he nevertheless catches and eats them after thorough preparation. Yesterday he was seen to disgorge one several minutes after it had been swallowed and then go over the preparation again thoroughly. (Is it possible that he was stung internally, but that he is more or less immune to the effects of a sting? Other thrashers (see earlier notes) are thought to have been stung here. Both, on discovering an especially delicate morsel, are apt to carry it to the other one with chuckles, clucks and other in-articulate sounds. This has been commented upon before and it is not clear whether the act is in the spirit of play, or whether it represents an expression of the parental instinct. These notes have recorded examples of the act performed both by mature birds (Brownie and Greenie) and by youngsters just out of the nest, and instances have been recorded where the food is transferred from one to the other, sometimes intentionally (apparently) by the donar, sometimes unintentionally with a chase resulting; also, sometimes the offer seems to have been made to invite pursuit. The two latest instances are:
