i too would love to taker another rescue in the rewards are amazing what you get back... my trouble is in the UK there's not many about for birds which is so sad

but i will wait till the right one comes along or i find one which will prob be by chance lol... good luck with your search and please don't give up... the right one will come along when you least expect it as everything happens for a reason..
I find this to be the case also. I found one and was quite excited (this was prior to having Cal). The basis of it though was not quite adoption. A short rundown was this.
You are home checked every six months rather than the usual initial and follow up. You must pay a subscription fee every year and if you do not, they will "rehome" the bird. I find this sad as perhaps people's circumstances will change but as the criteria was very strict, it is possible a lot of people would break it and the bird would surely be shoved from pillar to post? I understand they feel they are doing everything in their power to do what's best for the bird, but I fear few would come forward for fear of doing something wrong and losing their now beloved pet. There were many stipulations including bans on non feathered pets and informing them if you move house/have a baby/etc etc.
I think it is more of a "foster" programme but again, not too stable for the bird if it will never officially have a "forever home." Just my opinion!
I try to view EVERY fid or any animal as a "rescue". People have and will continue to breed pets in an already overpopulated sector. Just because you have had something from a baby does not mean you have not saved him or her.
For example, I have hand on heart GENUINELY seen an advert in Loot in this area which said: Parrot with cage, will swap for an xbox 360.
It did not stipulate what the parrot was, but regardless....to swap a gorgeous, wonderful companion for a CONSOLE?! Disgusting.
The RSPCA and other rescue centres are packed out with many MANY animals. What animals? The brothers and sisters of the pets WE purchased as babies. We know our pets have their forever homes where as once the "cute baby stage" is over,money problems or downright cruelty their siblings may not have been given the same good fortune.
I will always donate to the RSPCA, I will always have the box here for customers (and us) to contribute to the PDSA, I will put money in ANY shaky tin I see for animals and feel bad I didn't originally go to the RSPCA.
Then I picture Olly or Boot or Luce behind the bars of those concrete cells and realise that if I had left it just one day before ringing those adverts, it could so SO easily have been a reality.
