8. The "chook chook chook," being, I think, the danger-signal to the young, to hide themselves; whilst sitting, and, I think, whilst flying also.

9. The low crooning note (one syllable) of content, which the two birds utter when together in neighbourhood of eggs (as heard by me), and probably whilst caressing.

10. The little querulous note uttered when the bird is in trouble or perplexity; also one-syllabled.

11. A low guttural note (I think of two syllables) which I heard the bird make whilst sitting on the ground in near neighbourhood of eggs.

12. A note like "jig jig jig," which I have heard whilst two or more birds were sporting together in the air.

13. A note very much resembling one made by Blackbirds, so that I at first mistook it for this, but cannot now remember the note itself so as to write it down. The resemblance, however, was remarked on to me independently[1] by a good ornithologist.

14. A low croodling sound, expressive of pleasure and tenderness. With chicks.

15. A low guttural note, something like "ho-oo ho-oo ho-oo," but impossible to write it.

16. Peculiar single note, like "quo quo."

17. The "quick quick—quick quick," like a sort of loud twitter, uttered whilst birds sport in the air together.

18. A note expressive of disquiet and impatience, short and of indefinite sound, often uttered at the point when the bird, unable to sit still longer, flies hurriedly off.

19. A low somewhat Parrot-like noise, like "tchug tchug tchug." I do not now remember why I thought it Parrot-like, but something in the sound must have caught my ear at the time.

  1. In conversation afterwards, and as a general fact. I was alone at the time.
