Thanks for posting this. Planning is so crucial. I am blessed to have a local sanctuary where 3 of my flock currently reside. Mine are always happy when I visit, but they tend to fly away from me before I leave -- they have made parrot friends and have their own lives now. They get emotional when I visit, seem so delighted to see me again, but as I mentioned, before I leave, they are already being distracted by their parrot friends who want them to go play, cuddle or what have. Granted mine were well socialized and easily transitioned. It was bittersweet -- I wanted them to be happy, but I suppose selfishly, I also wanted them to really miss me. My sanctuary has many large designated enclosures (well, the place has macaws with other macaws, amazons with other amazons, etc..) Eggs are taken -- no breeding allowed. It's a forever home -- they never adopt out.
I also wondered if euthanasia would be best. I knew I didn't want my guys to go into private homes. I couldn't trust someone else to give them the home I'd given them (I had my guys for 20 years). I know people get bored with parrots and parrots are nearly always rehomed many times during their lives. After the novelty wears off, many parrots never get time out of the cage or receive fresh chopped fruits/veggies, rice, noodles, "people food" etc.. Many are lucky if their water is changed regularly, many end up on all seed diets. I just write all this out because it's all our fears, really.
I kept my grey though and he is still with me. I only kept my Snickers, CAG, because he is an intense parrot and very attached to me -- had him almost 26 years now. So I do get it. But I admit, now having visited my guys at the sanctuary for 6 years, they also have an excellent grey set up there too (they have 2 huge grey enclosures so that greys who get along well are kept together in one or the other) and all their greys seem happy and active there. Actually, there is a third enclosure (smaller) where a lone grey resides. He was bullied so gets the benefit of being near other greys without having them pick on him, No idea the full story there but he seemed happy (talking, curious, NOT doing repetitive crazy behaviors or feather picking or anything).
When I die (or sooner, since I become more disabled by the day) my grey will also go to that sanctuary. I say do your research, make sure it's a place with good back-ups in place, a board of directors, a place that gets lots of funding. I had to pay big bucks to place mine.
And if you decide to euthanize instead, well, I get that too. And if you decide on a trust for them, knowing ahead of time who will take them -- I get that too.
I was lucky a sanctuary was created just 20 minutes from me. I am in a rural area and so is the sanctuary. The macaw run at mine is 60 feet long. Not the same as free in the wild, but still, they do fly, have lots of fresh healthy stuff to feast on, friends to groom (and be groomed) and have lots of stuff to climb on. The guy who opened mine had macaws and saw a need -- his were the first parrots in the sanctuary -- now it has a staff and 450+ parrots.
Don't rule out sanctuaries if one isn't near you -- if you're dead, you wouldn't be able to visit anyway. I am disabled, hence the blessing of placing 3 of my 4 before my death and getting to see them happy and settled. My only goal is my parrots be happy and healthy. But happy most of all.
Sorry this is so long. But I've been down this path, and Snickers will also go down this path.
