In 1987 (24 years and 1 day ago to be precise...) we had wild winds in Melb. Blew my 12'x6' aviary half way across the back yard. Been paranopid about no floors in aviaries ever since. Lost lots of birds (finches & parrots). Pulled aviary upright and up against house after re-capturing the longtail hen who remained hiding in her upturned flight. Two mornings later opened kitchen blinds to discover our two red-rumps
back in the aviary, they had crawled between brick wall and aviary wall and in through a hole in the twisted wire and frame. Safely home, they were contentedly singing and having a feed

.
Glad your story ended happily. We heard the missing longtails for a few days and likewise the blue wings but for the most part it was a sad ending for us.
