Helen & Jos:
I've never seen a snow goose either but there is a cafe by that name half way up Ben Nevis in Scotland. We visited it in January by means of the ski gondola, ate some good hearty food, took some photos and came down again. I'll be delighted to think that my waltz is being played on the other side of the world.

The challenge to write a tune about fruit bats, ravens, crows (carrion or otherwise) is interesting. But does it have to be a waltz? A jig, reel, hornpipe perhaps?

Anyway, I'll have a go but might (as Captain Oates said) be some time.
