(536) the trees began to roar again, I still heard it, and it occurred to me to listen at the box( temporarily covered to allow the youngster to have a nap) and to my surprise, he was the musician! This is true to precedent in respect to time, for he is now a month old, but he can neither walk nor fly, nor sit on a perch, nor feed himself and, in addition, is distinctly an invalid. The song, while not elaborate, is soft and sweet and unmistakably the thrasher quality. Another Norther. 2:25 P.M. When there is a strong norther all the birds make for the sheltered south slope. When I went to the glade just now there were no signs of B&G, but they finally came, after much calling, from Thrashers overawed. the chaparral on the bank by the side-walk. Greenie first, plainly overawed by the sound of the wind and listening acutely in all direction. Possible reason for fear. Brownie was more phlegmatic about it. I am sure that it is not the physical discomfort of the wind alone that annoys, perhaps its noise is obliterate other sounds, the hearing of which are necessary for their safety. In any event, they stick very closely to the brush and are reluctant to come out of it to me even when they will not be exposed to the wind by so doing. G nesting reflex. After both birds had eaten all the worms they wanted, Greenie began picking up twigs, carrying them in random directions, and then dropping them, although, once or twice she did look up into trees with twigs in her bill as if about to carry them up. The twigs were of large size and were definitely selected with discrimination. The nesting instinct seems never to be entirely dormant in these birds. Full song subsiding? There has been no full song for a week or so, but some sub-singing occasionally. November 29th. No observable improvement in the young bird in any respect. Some undersong by the parents. November 29th.
