Hi, I adopted my first B+G macaw from a rescue last year at this time 9/08. She was about 15 yrs old. It has taken me most of this entire year for her to really warm up to me. I started with baby steps. First I would stand by her cage and talk to her and give her a small treat when she was out on her play stand, then I would put my arms on the cage and lean my chin on them. Next, she let me scratch her head. All this time she was right in the living room where I could interact with her on a moment to moment basis. We are now very close friends. She gives me kisses and rides on my shoulder while I do my chores. She is very sweet and loving but, we went at her speed.

In the dog world, experts say it takes two years for an adopted/rescued dog to fully acclimate to its new home. That I know to be very true.
Good luck with your new babies
