It take an "older" parrot a bit of time to get adjusted to you and it's new surroundings. If you have a square flat top cage, you can make a "jungle gym" from wood dowels or sisal/jute/hemp rope wrapped around 1/2"-3/4" PVC. Place it on top and hang a few of it's toys.
Here's a link to get an idea:

When I was with the X, I had a Blue Front Amazon (Charlie) and she and the Goffin (Monty) hung out all the time and play chase across the gym that spanned between and over their cages. Keeping them clipped, they were free roamers, rarely ventured on the ground and only went into the cage to eat, drink and sometimes sleep.
I miss them alot.
