1095. Archie's bill. The decurved tip is now flush with the lower line of the lower mandible; but this is still short of normal as determined by comparison with Terry, Rhody and skins at M.V.Z. "Worm-box reaction". Archie continues to respond promptly to sight of the worm-box; but Terry not at all, unless first shown a worm. A may or may not react to the "frog" sound given out by it. Rhody and young. Rhody continues to be interested in the young birds; but the talk is still all by them. At these meetings all three may swing their tails slowly back and forth in a horizontal plane. This gesture seems to be used principally when in contact with other road-runners, though not always. Pellets. No pellets have been found since the seventh on Nov.11th. Skin-color change. (See Nov. 13 an 14). Confirming the change in color of A's bald spot from "white" to slate: The bare patch exposed by the debacle of Nov.14th. (The second bare patch) began to change to a darker hue noticeably the first day. "Replacement of A's head feathers. This has progressed so rapidly that, unless the crest is erected, the head looks normal. "Rumbling bowls" Sometimes when one of these little fellows is sitting close to one of my ears I can hear a "rumbling" of his "bowels", showing, I suppose, that these creatures, notwithstanding (or perhaps be- cause of) their extraordinary digestive powers, are subject to flatulence. Occasionally, also, one or the other has been observed to discharge fecal matter composed largely of bubbles. Excretion. These birds do not foul their roosting places and there is no accumulation of excrement below them. This applies to Rhody as well as to the youngsters. Usually a very considerable mass of excrement is discharged by each bird, at one performance each morning sometime before 9 o'clock, or thereabouts. Thereafter, during the rest of the day, but small amounts, individually and in the aggregate, are voided and at infrequent intervals and it seems to me that none of the food eaten during the daylight hours is ever completely digested in the same calendar day, and the waste rejected. Thus the fur of a mouse eaten even in the early morning does not appear in the excrement until the next morning. December 1st. to 10th., incl. During this period all of the birds under observation, except the hummer at night, have been contacted every day. Thrashers Brownie has been very quiet and appears to be roaming about to considerable distances. One morning he was heard scrippng over at the Robinsons' 250 yards away, but on being called from here, came readily enough to eat from hand. It was noted, however, that, on the journey toward home, he went from bush to bush, on the ground and kept a sharp lookout for hawks, and even while with me, kept a weather eye open. Nothing was seen (or heard) of Nova or other thrashers.
