Negative reaction to skunk odor, by A, T and R. A spotted skunk ("Civet cat") was caught in the box trap trap within a foot of the poultry wire mesh of the cage. When shot with a 22 calibre rifle, a thin white mist arose from the trap carrying the characteristic, powerful odor. The two young road-runners gave not the slightest heed to it, although the odor in the cage was almost overpowering. Later, after the trap was washed out with a hose and placed in the sun, still smelling strongly, Rhody used it as a perch on which to stand and sun himself, evidently not objecting to the odor and having no associations connecting it with danger. R and young. Rhody seems to be as much interested in the young birds (and as little parentally) as ever. He seldom, now, makes either of the calls formerly reserved for his children. In fact, today (24th.) it was Archie who used the goose-like call, inspired by Rhody's presence, as both manoeuvred about to get a better look at the other. R and mirror. R absolutely ignores the mirror. The real birds seem to have usurped the place in his "imagination" formerly occupied by the phantom. R's roost. R continues to roost at night in the same tree where was found on the 17th. September 25th. Thrashers No changes noted. Road-runners Moult. Archie is beginning to replace the moulted eye-lashes. (See later) Bed-time behavior. As bed-time approaches, the birds become restless, just as they did when, as babies, they were allowed their liberty in the shop-yard. At this time Archie is shy of Terry, even on the ground. This evening, however, after both were in their accustomed place Archie apparently forgot about his experience when he climbed over the partition last time, and tried it again, with exactly the same result as that previously recorded. The partition will be raised. September 26th. Thrashers Everything as usual, but Roughneck was present at the upper feeding station, and Brownie indulged in a long quarter-song at his night roost in the middle of the day. Road-runners Relations between Archie, sitting on my lap, saw Terry 15 feet away, back toward us, investigating a corner of the cage. He rushed up to him, pecked him once and "drew feathers". T did not retaliate. So far neither bird has ever been seen to return a blow. Two or three hours earlier Terry had resented Archie's too great interest in a mouse that T was preparing to eat, and had drop- ped the mouse and made a short rush at Archie, causing the latter to retreat hastily. The partition dividing the two sleeping place into two chambers was extended to the roof today. Terry noticed the change
