October 14th.
No early morning song was heard.
At 8:15 Greenie was in the nest, Brownie in the glade. The latter after taking but 4 worms, climbed the old oak and sang full song for 30 minutes, sitting perhaps 50 feet from the nest. The song was not continuous during this period. It was harsher than I have heard from this bird before, and it was changed frequently. Toward the end I imagined that the bird became hoarse--if such a thing is possible. (8:50. The song continues).
G answers from nest. After 25 minutes Greenie answered from the nest softly once.
G calls. B continued, then G called loudly perfect, perfect, just as B changed his song to one containing the phrase yer-r-r-kit, yer-r-rkit, strongly thrilled. B went to the nest and sat on the edge, both talking silently. They did not change, but B went to the glade where I followed. He was much excited, as shown by his rapid movements. His pupils were expanded giving him a wild appearance. He came to me for one worm at a time, flying part of the distance and taking off with a hard push each time to run through the bushes. Clearly much excited. (9:07--still singing loudly). I do not know whether the excitement is because an egg was laid or because none was.
An egg? Singing stops. At 9:15 singing abruptly ceased. I sent Julio out to have a look and he said G was in the glade. I went out a few minutes later and verified this. Greenie looked dumpy, would not come for worms, and even worms tossed to her, she would turn over with her bill and eat only in a perfunctory way.. I went to the nest, finding B there.
B, on nest pecks me. He protested silently at my meddling about the nest and pecked me. Grips lining He sat xx tight and gripped the lining with his feet so I retreated Ungentle temporarily. He does not seem to be so gentle as formerly.
G recovers spirits. At 10 Greenie was no longer in the dumps and ran up to me for worms in the glade as soon as she saw me. The last one she took to the nest. B left when she was 2 or 3 feet away and the worm was seen
