I too did good research before i rehomed my birds..
i had 2 Senegals (one tame, one not) an Amazon (came to me as a rescue, heavily abused) and a Grey (would NOT stop trying to mate with me..) So while i first thought you know what, i can fix this.. i soon realized that with the depressions i sometimes suffer, i could not fix this. So both the large parrots went to a subsidized sanctuary here they will stay forever (in theory, one can never be sure what the future brings, i know that now) and they where kind enough to took the two Senegals in as well..
The amazon is now nicely paired up with another amazon of a different species, but hey they match
The grey is part of a flock of 12 greys, and the Senegals.. well luckily i gave them the outdoor aviary as well.. because they molested a mackaw so they placed them i their own aviary
All birds are happY now, much happier then they ever would be with me.
And then.. Then came the call if i wanted to rescue two Pionus birds. and i SO SO was in conflict with myself.. how could i give away 4 birds, only to take in 2 new??
But you know what.. I gave away the 4 for a better life, and i decided to take in these 2 for a better life and see what happens. And you know what happened? They turned out to be the perfect fit! They are calm, self caring birds that need not as much attention as the first 4. Whenever i deal with a depression, i can safely spend less time with them, and know they are still happy and content.
So understand.. nothing in life is set in stone. If the present forces you to rehome the birds, then do your research (as
@webchirp also said) rehome them to a better place and be at peace. For all you know you die next week in a car accident, and they need to be rehomed anyway (but please, stay away from cars! And be safe)
