Sept.11th.
The day opened overcast, but with much full song by B and others.
On my way to the glade to locate the birds at 9 A.M. I passed under a
tree in which sat Nova scrapping. B came out of the bushes and sat
for a long time, occasionally making soft gurglings. I tried to make
him sing by crude sounds without success. When he climbed to the top-
most snag of the old oak he began with calls (probably for Nova) and
swung into full song. By whistling, what sounded to me at least, a
reasonable imitation of his whistled: —— (p.474)repeatedly
I hoped to get him to take it up, also without success. However,
when he changed his location to the dormitory tree behind the screen,
this call suddenly rang out detached from all other sounds. As it
brought no results, he mounted the screen facing me and repeated it
several times, turning his head to look in all directions, I suppose
for Nova. He got no response and retired to sit on his platform.
There seems little doubt that, on this occasion at least, his
singing, and particularly the musical phrase referred to, had the
purpose back of it of attracting other birds, presumably Nova.
He introduced two variations this time; the first one contained a
repetition of the the first note at the end, thus:
B
The second repeated the last note, thus:
C
The intervals here are believed to be correct. The lengths of the
notes and the technical correctness of the representation are not
guaranteed!
Shortly after this B was at the oval lawn, very talkative, and was
there joined by Nova, herself, who shows a liking for pyracantha
berries. She behaved in a quite civilized manner, but at her tamest
she is not so tame as Greenie at her wildest.
