The tui is a New Zealand native bird. It has a white tuft under its neck, which is why in the early days it was called the parson bird.
In September there are dozens of them on my street. Afterall, I do live at 12 Tui Glen Drive! They come to feed on the nectar of the flowering trees.
In this piece of music the tuis can be heard calling over the music. Sometimes they sound like little bells, and other times like a truck revving or backing!
