Bonnie let me stroke her tummy and her beak for quite a long time, and she even chirped at me while I was petting her tonight. When I tried to get her to step up, she scooted down the perch but she didn't hop over to another perch as usual, just moved to the side, and didn't seem unduly upset. I can't figure out how to get it through her head what I want her to do.

When I press gently against her tummy and say "hop on" (that's what I said to teach Clyde and now I don't even have to say anything, just offer the finger and up he goes) and she'll look at my finger like "WHAT are you DOING?" but she won't step up. We sit in front of her cage with Clyde with him sitting on a finger and she's VERY interested. I keep hoping she'll make the connection and think, "OH. Finger = perch. I see!" but so far no soap.
Any suggestions?
The good news is, she's stopped freaking out when I change her paper. She doesn't seem to mind hands in her cage much. I changed her paper tonight and she didn't even bother to hop away as usual. She just sat there and observed. She doesn't boss the job, the way Clyde does

, but not freaking out is a major improvement.
I never had to tame a bird from scratch before and it's taking longer than I thought it would!
