(278) At 3:25 I went up to the nest. Greenie was in it. I wanted to test her on taking worms while in the nest which was about at the level of my eyes, the platform being too low. As I had the worm about 6 inches from the tip of my nose, the cheeky Brownie, who, I had thought, was nowhere around, calmly gulped it before I even saw anything but the tip of his bill. Greenie left the nest and B stepped in, reaching for more worms before I could get them all the way to him. He sat with his bill open to cool off and I noticed that he left a space between the eggs and his body, contrary to usual custom. Whether this was for his own comfort or for the purpose of regulating the temperature for the eggs, I do not know. About 4:30 I tried Greenie, again in the nest, with a worm. She promptly froze. I laid it by her bill. She waited until I had descended, then ate it. A little later when she was off duty in the glade, she ran to me, stopped about 4 feet away in front of me, raised her head and tail vertically, spread her wings slightly, crouched, and in that position "danced" a few seconds in a small circle, her head toward the center. Brownie was not present. This is her invitation to the male, After that she jumped up for worms. At 5:21 Brownie, on hearing Greenie scrapping in the old oak, left, and said softly, twice: C2 c1 Pyor-rah , keent I checked my recollection of the pitch on the piano when I came in, and it is given above. I then recalled, or thought I did, that I had previously tried to represent a phrase like this in musical notation, so looked back through the notes and found that I had. (See p. 444). The difference is not great, in fact the pitches are identical. It would be interesting to know whether the slight difference is due to personal equation or to a real difference in the call.
