sometimes accident's happened. I believe this might be an extra ordinary things which could broke the 7 yrs solid bonding. Did the bird just go away and never come back? Something scared him/her to death? I have been freeflighting my fids for two years, my SC is the first freeflyer. Eloy if you could give the detailed informations on the cause, we will appreciate that.
Yes the bird left from the shoulder and fly out to the ocean and later on drowned. I don't know what scared the bird, (perhaps a hawk or a seagull) the owner died in cancer the year after. Very sad story.
The bird have not being training in free flight but has never before left the owner. And that for seven years!
@Mudkips. Awesome clip!

I have Eloy as what you told, safety. But I say that he have a great life.
He is never in the gage, only for eating and sleeping. He has freedom, but not outside. (when don't have warm weather so many month a year either) When he is out I have a outside cage or the Aviator.
He is not having a boring life, and he is of course not clipped.
Safety is not boring and means wing clipped. But yes you have to work a little bit harder as the bird is free inside. If you free flight your bird (how long? 30 min/day?) if he is in the cage the other hours of day I prefer to have it my way. I Know that Eloy is feeling free, and thats important to me.
I have nothing against free flight outside.(so don't got me wrong)
I love to watch clip on YT. Birdtricks.com is awesome!
But I never dare to do it myself and risking to loose my bird.
