1475 posture of the adult thrasher, one wing raised to let the sun strike into an "arm-pit"for a few seconds, then the wing is lower- ered. I find, also, that they too have a "spread-eagle" pose like Rhody's. In this, unlike Rhody, the preen gland is exposed to the radiation. Thrasher preen gland.(Vs. R's). Without having had an opportunity to make a direct com- parison, this gland appears to be much larger in proportion to the size of the bird than in the case of the road-runner. Personalities of O and C. Okii and Chiisai have distinct personalities, and the differences noted in the beginning still hold, and, in some cases, have become accentuated. The difference in size still remains. At one time it ap- peared that Chiisai was catching up on Okii, but the latter seems now to be forging ahead once more. Chiisai continues to be more dependent upon me for food and is less self-reliant in other respects. For example: At"bed- time" he is much more restless and responds to guidance in seek- ing a roost.more definitely. At this time he goes about from place to place constantly yipping (or kipping), but if I hold a hand near some point that he is considering, he climbs up to it and settles himself comfortably upon it with little gurgles of satisfaction, closes his eyes and prepares to spend the night there. Okii has not been doing this, but last evening at 7:50 P.M. I went into the cage, placed one hand against the wire of the door about 7 feet above the ground, and Chiisai at once climbed up the wire to it. Okii saw this, climbed up the wire of the magpie cage, shifted horizontally across it and around a corner and joined Chiisai, who had (as usual) ceased yipping. Both were then transferred to a more permanent abiding place. The difference in self-reliance is also shown in their daily behavior. O feeds freely from the various dishes--C much less so. O seldom calls for food. C is "always" yipping and tagging me about, and often refusing food when it is offered, even on his own solicitation. He is much harder to rear. Neither bird cares much for meal- or angle-worms--both seem to be "last resorts". Their tastes in foods differ. Thus: Okii, differing from all other thrashers of my acquaintance, is very fond of chopped apple.Chiisai almost completely ignores it. On the other hand, he likes hamburger (which Brownie always refused and O seldom will take. In fact, hamburger, thus far, seems to be the only food aside from the centipedes and other things he finds in the earth brought into the cage, that will stop his yipping. Sex of thrashers. Okii still sings a little-- Chiisai far less often. If I were to make a guess now, it probably would be that they differ in sex, Okii being the male. There is no distinction whatever in markings. Thrasher digging. Early in these notes it was suggested that the thrasher is the"digger of diggers" These youngsters are "the diggingest" thashers of my acquaintance. They dig under everything--all the time. If I stand still for a moment they are digging under my feet. If I put a hand down as a support, they dig under it. Food of almost any kind placed on the ground before them- even just one worm--is usually dug about and under . Okii especially, is always digging at my shoes and ankles. Rhody was seen to visit his nest 8-37 every day during this period, though not seen working at it. He came for mice as usual and displayed with only a few of them.
