Road-runners 1073 Moult Terry has now moulted all but two of his broken rectrices; Archie none. (This is 6 for T). There does not appear to be any moult of flight feathers, although over a period of several weeks, two have been found. The "soft" feathers continue to be shed and there is still much work on the plumage in removing loose feathers and sheathes. "Grooming" Both birds like to be smoothed down gently with a stiff feather and will submit to the operation for an indefinite period, seeming to invite it, occasionally emitting soft "grunts" and nibbling at the feather. Mouth color. Terry is still behind A in change to black. Possibly he will never change so completely and this may be a characteristic sexual difference. Sizes T remains distinctly smaller than A and A is smaller than his father in every respect. As a rough, visual comparison, using a human basis: Terry is a "man" weighing, say, 150 pounds; Archie 175 Rhodie 200 and more. The birds have not been weighed since last record was made. Sexes These are still unknown. Pellets The sixth pellet has been found; again composed principally of mouse-hair. (Five days after the fifth one). (the birds Fear reactions. A niece whom the birds have seen a few times at the cage, becoming only slightly restless), appeared in riding clothes on the 12th. Both birds immediately flew into a panic which subsided only after my niece retired to a distance out of sight. (Colors: Blue, olive drab(?) and tan leather). A reclaims former roosting place. Archie recovered his sleeping place from Terry by the simple process of getting there first and repelling attempts of T to enter it while A was in possession. T gave up after two attempts on succeeding days and ignores the place entirely, not even sleeping in the other room on the same shelf, but taking a new place made for him. October 15th. to 18th., incl. Thrashers Decrease in song. This period has been marked by decided decrease in the volume of thrasher song, both by B and by other birds in the vicinity. Early morning song has been almost entirely stopped. It is so quiet during the day that, several times, I have wondered if Brownie had decamped, and have looked for him, usually finding him somewhere on the place ready to come to me for worms. No nesting(?) He has shown no further evidence of a desire to build a nest here at this season. I anticipated, last year, that his post-season, autumnal nesting activity would fade out to nearly nothing this year. Roughneck This bird has not now been seen for weeks. B's wing. The gap is still in B's left wing, with no external sign of its being filled.
