hour and a half, beginning before four o'clock. B seemed to be in a song contest with a thrasher off to the south west and fairly extended himself. Both he and Nova went to nest 9 frequently and about 11:15 N was seen in it, staying there about three quarters of an hour longer. B was given worms, some of which he took up to . her. Altogether it looked like a genuine nesting operation, but when B relieved Nova and them left after a few minutes in the nest there were no eggs in it. During this time B was very quiet, sometimes sitting on the screen near the nest as if standing guard. Rhody's presence about 25 feet away on top of the lath house lent some color to such a supposition. R was about "all" of the time, sometimes making his mournful song when standing on the ground immediately in front of me. In making this call the bill is entirely closed. > Once, for no ob- vious reason, he had a fit of "rattle-boos" in which the calls were uttered in rapid succession, giving the impression of an expression of intense disgust with everything in general. March.6th. The day opened with song notwithstanding a cold wind from the south. About 9 everything was quiet, a thrasher was on the nest and Rhody was squatting on the ground (where I nearly stepped on him) near the dormitory tree avoiding the wind. At 11 A.M. a loud outburst of song from B in the direction of the nest. I went there to observe results but as Nova was stick- ing manfully on the job I did not risk disturbing her. B had shifted his singing post to a point where he was fully exposed to the gale on the south slope. The wind screen protects the nest on all sides but the south. That side is, however, fairly well screened by the tree itself and other trees to the south, so while the nest is swaying about somewhat, the wind does not strike it strongly.
