Very good advice. I'm always leary of those ads that state "We are sadly rehoming our bird because we just don't have time for them anymore." That usually spells DE-SOCIALIZATION to me. I would ask them to demonstrate how friendly their bird is before bringing it home.
I got a Senegal from a previous owner from Craigslist, which was 11 months old. The owner said that they hadn't been spending that much time with her lately because they got a new puppy and the puppy would try and eat the bird. So she hadn't been played with that much within the last few months.
Sure enough, when they brought the bird and cage to my home and I asked her to demonstrate how tame it was since she claimed it was hand fed, the Senegal (Tiki) tried to bite her a couple of times, but you could see where she wasn't really mean or vicious. So we agreed to take her. It only took me a couple of days to get her to stepping up and socializing with us and then with a month, she was a really cuddle bug.
So if this is your first bird experience, please go slow with the transaction, realize first hand what your getting into and take what the previous owners say with a grain of salt. Sun Conures can be NOISY BIRDS, which is why quite a few get rehomed. So if you live in an apartment, this could become an issue.
Now with Tiki, I didn't even open up her cage for the first two days and just let her get used to her new home and being around new people and activities. I just sat at her cage talked to her, read the newspaper to her and then the third day, she was ready to come out of her cage. It was love ever since.
I don't mean to rain on your happy day, but I believe in a person being well informed and Know exactly what their in for. So there shouldn't be any buyers remorse in the near future.
Good luck with your new baby.
