assure himself that I really intended that he should eat the miserable creature, then took it dutifully. What was the pattern here? August 22nd. No thrasher convention seen at or heard from this place today. B and Nova (presumably) were frequently seen quietly attending to their usual affairs. August 23rd. No convention seen or heard here, but one heard in the distance. Dr. Reynolds says there was one at his place this morning. At 5 P.M. soft song was heard from the dorm. B was in his night roost and nesting site there. Last year this action preceded the building of a nest there. (Think Sept.). At last an unmistakable pellet has been found disgorged by one of the young road-runners today. It seems to be entirely composed of mouse hair, but will be examined more in detail. The event is so rare with the birds under observation that it must still be held that the evidence to date is that road-runners do not make regular a practice of disgorging those portions of their food usually class- ed as indigestible. August 24th. Well! Another pellet found this morning. The first one, dispersed in water, contained only mouse hair as viewed by the naked in addition eye. The second one contained fragments of two teeth. The surface of the water looked oily. At about 9 A.M. a thrasher was seen running swiftly along the lower road, dodging into the bushes when it saw me. In a few mo- moments Brownie emerged in pursuit. He halted when spoken to and came for meal worms. The matter did not appear urgent. Possibly this means, taken in connection with B's renewed sitting in the dormitory, an awakening of B's reproductive instinct. It is about time for some show of late nesting activity as in previous years.
