(289) incidental thereto. 8% in resting and dozing. 58% in preening. 9% in miscellaneous activities. TOTAL 100% It should be noted here that Brownie's preening was not of the recorded frantic type previously [illegible]. It seemed to be engaged in, not by force of circumstance, but by voluntary choice. In the last day or two she has made herself look a little sleeker. The younger sat in one place for 50 minutes of observed time and for a considerably longer period undoubtedly. At no time was he clamorous for food and for at least 50 minutes showed no anxiety about it. During that period he dozed frequently. There were no signs indicating that his nest-mates were in existence, unless Greenie's long absences and quick departures are connected with them. Brownie once or twice picked up and dropped soap-root fibres, other- wise there were no actions that might be considered as indicative of a desire to build again. This is a thrasher call as near as I can get it: "Chew'it, Chew' it, Chew it,' early, early, early, Murphy, Murphy, Chewit Murphy." At 7:05 P.m. young thrasher No.4 was all alone in the glade. Soon after I entered he began to "yip", and as he was accessible I approached him with a spatula of soft food which he ate greedily. It has been observed, but not recorded, that this young bird has now the same color of iris as Greenie and the three older juveniles. All three of the second brood were showing this tendency very plainly before they disappeared. To date Brownie is the only thrasher of the eight with the bright orange hue showing in her eyes. It begins to look as if brownish olive might be characteristic of young thrashers, again suggesting that Greenie, himself, is a young bird and that the difference observed in the two adults is due to a difference in age and not a sex difference.
