G'day again Haruo,

I just noticed your reference to "orana" and "brolgas". Orana is discussed way up in this thread, but it is an Australian Aboriginal language word for "dawn" or "welcome".

The Brolga is an (eastern & northern) Australian crane, grus rubicundus ... grey with red features, and noted for the formal "dance" of its courtship behaviour.

I can't help you with the Esperanto versions ... we did have some keen Esperantists about the Bush Music Club in decades past ... but not currently!

Regards,

Bob
