the highest point, ran for a few yards more and again sailed, the total distance covered being about 150 yards. He then headed for his night roost, although it was only 2:30 P.M., sat for 10 min- utes on the rail below it watching hawks and t/aking worms from hand. At 2:40 he was settled in his night roost--the earliest retiring time yet noted. Feb. 21st. Heavy fog in the morning, clearing up about 9:30 A.M., but B singing as usual. Rhody came to me of his own volition without being called, about this time, and was soon followed by B, also on his own initiative. There was some restraint on B's part as regards R, but R paid no evident attention to B. They were handed one worm at a time alter- nately, B soon climbing the old oak to sing, Rhody, somewhat later, somehow (I did not see him do it) got on top of the tower of the observatory and called for 50 minutes. I trained the movie camera on him with a telephoto lens hoping he would get up on the weather- cock, but he sailed down and landed at my feet. (About 110 feet, along the line of flight). Feb.22nd. The usual singing by B, but no activity at the nest whatever. At 9:30 Rhody was sitting on the wind-screen which shields thrasher nest No.9 in the dormitory tree, calling occasionally. He sat there for three quarters of an hour, then moved to the small roof over B's nest and sat there for 25 minutes--hopefully waiting? Next he delivered a few calls from the screen again, then sailed down to the cage where I was sitting, got meat from near my elbow, passed by the mirror several times without getting excited about it--merely a casual glance in passing--and moved on to see what else there might be of interest. In the afternoon he came to watch me digging in the orchard.
