1505. There are still other effects. They are now less certain of making either good take-offs or landings from or to perches--they have become awkward and have incipient falls. The weighted leg appears to lag in starting and arriving without the bird's being aware of it. The weighted leg is favored in perching, being lifted up and placed beneath the feathers. Even this placing is interfered with on account of the unaccustomed bulk of the band. Again: the bird appears to tire sooner in holding this leg up and become restless. While they do not now peck at the bands very often, they appear aware of them in every move they make. In short, they act like the slightly crippled birds that they are. Some of this will, no doubt, be overcome; but there is little doubt in my mind that, no matter how long the bands are allowed to remain, the pedestrian activities of these birds, as long as the bands are in place, will be definitely impaired and unthrasherlike, and that apart from any considerations of actual physical injury. August 18th. to 20th., incl. During this period "pressure of other affairs" prevented my giving close attention to the birds. However, during these days, Okii and Terry failed to become reconciled to the handicap of the bands and, although it may have been due to excess of imagination, it seemed that they sought the seclusion of their retreat in the upper portion of the inner cage more, and were somewhat more shy of man. In fact Julio complained that they had now formed the habit of running away on his approach. Examination of their banded legs fails to show any surface damage, but it is noted that the tarsus of each banded leg appears to be polished as compared with the other. Moult of Okii and Chiisai. Chapman, in his book Bird Life (1914) makes the statement: "At the close of the nesting season all (the italics are his) birds renew their entire plumage by molting." "All" necessarily includes birds of the year as well, perhaps unintentionally. In this connection it is to be noted that, as yet, the moult of Okii and Chiisai appears to have been confined to the "soft" feathers, the rectrices and the wing coverts. Here, again, it is to be noted that I have heard it asserted that young birds, in their first moult, shed only their "soft" or body feathers. It is quite evident that Chiisai, the more juvenile in appearance and behavior--in most respects--of the two birds is further advanced in the moult than Okii. Both still retain vestiges of the natal down (?) on the back of their heads. Song. Chiisai has been heard in one or two short snatches of approximate full song. His digging song is now in no way inferior to Okii's, and when he has stopped digging, he is apt to continue the song from a perch. Rhody shows seasonal form. Rhody appears to have forgotten all about building nests; no longer displays on receiving a mouse; does not tail-wag sideways; does not carry it about and does not present it at the mirror. He does, however, occasionally look at himself in the mirror, but without vestige of excitement. All this appears true to seasonal form.
