They likely won't start returning for another three weeks so there
might be time. Mine went up on 8th May last year then it took me
another week or two to get the speakers fixed up. I had them passing
seriously low over my garden so I could hear their wings cutting the
air and buzzing the back of my house within a metre of the box I'd say
so I'm hopeful for this year.

I'm told that the first lot that return will go straight back to the
previous year's sites then the next ones are the prospectors that you
want to attract.

Do you have box design ideas? Any more of this and we'd better go off
topic, but the more people inspired to help nature the better and
Ubuntu is the best way I could think of to play the attraction sounds.
