that feather now has a V-shaped notch at the tip. Perhaps illustrative either of thrasher tolerance at this season (or their present tendency to wander outside their terri- tories) I was surprised, on seeing a strange, ragged thrasher in the moult at the suet feeder, to find that it was Roughneck, still with his crested neck feathers and tamer than any of the other thrash- ers except B. I have frequently observed, but failed to record, that A and T's gaping when spoken to is frequently followed by vigorous scratching of the throat and sometimes of an ear as well, as if an actual irritation had been caused that was no longer tolerable. Today when Terry was sitting reposedly on my shoulder, I found that he would also react to a whisper, gaping and scratching. This does not seem to fit in well with the theory of irritation due to vibration, unless we make some additional suppositions, such as, that frequent sensations of irritation accompanying similar experience in the past have produced a sort of "complex", so that the bird responds by reflex action to a similar, but milder, stim- ulus. (This is not exactly what I mean). August 30th. Early morning thrasher song, occasional sub-song during the day. Increasing (?) tolerance of childrens' voices on the part of A and T. Rhody very much in evidence and sticking pretty well to the immediate vicinity of the house. August 31st. Much early morning thrasher song until about 9 A.M., thereafter almost continuous sub-song by B until 11, at which time I interrupted him by offering worms .
