It crawled beneath his feathers and there was shortly an exhibition of pyro- technics viewed at close range. On such occasions, the thrashers seem to be suspicious of everything near at hand for the time being, and are extremely nervous, even retreating precipitately if I allow my body to sway slightly, though returning almost immediately. Sept. 30th. At 5:40 A.M. the first thrasher calls and short songs were heard, but they soon ceased.
