I am so sorry. So very sorry. But I have to agree with Anne; I wouldn't have an outdoor aviary without a entry vestibule so there is a double door between the birds and the outside world. That way you can go in the vestibule door, close it and then open the aviary door. If a bird gets into the vestibule it can't get out to the wild and you can catch it and get it back into the aviary. No more birds lost to the butchers. Poor Wingli. How unfortunate.
