Okii's slumber song. While Chiisai was being attended to Okii sat upon a nearby perch and sang. This song, I had thought earlier, resembled Brownie's slumber song. As if to confirm this diagnosis, Okii now put his head under his wing and continued the song. Rhody now came and stood close to the wire to watch oper- ations. Chiisai, who was sitting dozing on my finger with head under wing and sore foot under breast feathers merely stirred un- easily. Okii said nothing. When I came out of the cage Rhody tagged along behind for his mouse, conducted it, with full ceremony, to nest 8-37, where, be- fore eating it, he several times essayed a rudimentary sort of full song, but of only three notes. 2:55 P.M. R still (or again) in his nest. I think he has been there ever since about 11:45. June 16th. to 21st., incl. (Notes written 21st.). During this period Rhody was about the place much of the time. Nest 8-37 was occupied by him a great deal and he was seen carry- ing pine needles up to it yesterday at 6 P.M. He sits in it mostly doing no work. Once again he was heard to utter a rudimentary coo-song when carrying a mouse. Most of the mice given him during this period were eaten at once: There was less display than there has been. Based on last year's observations, this would indicate decline of breeding urge. Still he is much concerned with nest 8-37. He loafed much in the vicinity of the cage where the young thrashers are. He can no longer get into it to study the magpies, as the door is closed. As I am often in the cage, the possibility of getting a mouse from me is undoubtedly one of the attractions. He will wait patiently close to the wire and, when I come out, will usually trot along behind to the tool-house. Once again, today for his second mouse, he lead the way. He still is afraid of numbers and small boys and girls. This morning Mr. Cain came with half a dozen boy scouts. Rhody was sitting over my head in a low branch of a pine at the north fence where I was repairing some damage. As soon as he heard the boys (he could not see them) he flew down and ran off to the north, not reappearing until they had left. Incidentally the young thrashers concealed themselves in the upper part of the inner cage with loud scrappings on this same occasion. Yet when I went in and touched one of them on the breast, he stepped to my hand and allowed me to carry him all about the cage and to the wire where the boys were standing and there exhibit him "sun-fitting", taking food and digging in a trowelful of earth all while sitting on my hand. He was perfectly composed. The odd part of this is that neither bird, now that they are get- ting older, likes to be handled, even when there are no visitors present. This was Chiisai. Okii, on seeing how things were go- ing and that C had not been massacred, flew out voluntarily and thereafter neither minded the boys at all. The young thrashers have now been in the large outdoor cage night and day since the sixteenth. On the 18th. Okii was out of custard's having been made the major portion of his diet, was much livelier. Okii was given the same treatment and both birds appear
