1491 Rhody now proceeded to the roof of the house and was still up there at 10:45, sitting on the chimney preening. Okii and Chiisai were still yipping and restless. July 20th. to 22nd., incl. During this period there were few new developments. However, it was found that Okii and Chiisai could be quieted if given meal- worms. So far this has worked every time and it seems that unsatis- fied appetite is at least one of the causes, still, of this yipping and restless moving about, and that actual living food, in addition to that furnished them, is necessary to satisfy their cravings com- pletely. When thus satisfied, they become sleepy and like to follow me out into the cage entry and there, provided I hold my hands high enough, climb up to them, lie down on them and doze, now and then reaching out to touch gently with their bills any portion of my anatomy within reach. Chiisai still wants to be fed by hand. Rhody showed a growing tendency to absent himself during the forenoons and to omit ritual when given mice. Thus, during this interval, only about one in four was thus honored. Thrasher song diminished again, although Broken-Wing seems to remain here most of the time. I neither heard nor saw the brood during these three days. Mr. Sampson says that a new thrasher, much tamer than Broken- Wing is now at his place. July 23rd. No new trends. Rhody is undoubtedly (unless he is building another nest elsewhere) on the downward slope, either of one of his nesting harmonics or the fundamental wave itself, for he has been neglecting all of his structures at this place for several days. A mouse given him today was also eaten without ceremony. July 24th. Okii sings full song! The great event of the day was Okii's sudden breaking out into veritable, rich, loud full-song . It happened as he caught sight of me about 50 feet away carrying a box of peaches just gathered in the "orchard". It was a keen surprise, as it was not only the first instance heard, but there has been absolutely no gradual development of this song from the immature sub-song, or from the slumber- and digging-songs. The latter two songs have differed fb from the sub-song--as far my ear could detect--only in the occasion of their use; that is: the sub-song--the substantial equivalent of Brownie's quarter song--has been used both when digging and when doa dozing. Moreover, since first it was heard, there seems to have been no considerable improvement in it either as to volume, musical quality or variety. Consequently this full-song has appeared not as something that has evolved, but as something that has "just happened". Another surprising feature of it is, as these notes show, both Okii and Chiisai's efforts at song have declined greatly in frequency since they first initiated them. Naturally, also, the fact that the bird is only two and a half months old and is, moreover, in the moult, makes the event all the more interesting. (O and C left their nest May 20th.
