Hi William & Sunny.
Please don't take this the wrong way, I'm not trying to be judgemental... you choice is your business and you don't have to answer if you wish not to. Just out of curiosity, why have you chosen a sanctuary instead of an individual? What are the pros and cons to you? I have thought about this in respect to my birds if something should happen to me and my family didn't want to or couldn't keep them.
Please, do as much research as possible before surrendering your bird. I know there are good and bad out there, and some that had good intentions to start with but ran into trouble... I have heard of sanctuaries going out of business, and or adopting birds out that were surrendered for permanent placement. Some became overwhelmed physically & finacially. And some are wonderful and are stable...
