Is there any reason why Tiko will step up when on the floor but wont any other time? I have been trying to teach her to step up and she is afraid of perches and will bite my hand maybe not hard but I dont wanna risk it.I was using the perch today and she kept flying away and landed on the floor and she saids Now and offers her foot and I picked her up and put her back on her cage.I really want her to step up normally when told.

A lot of birds feel more vulnerable when they're on the floor. In the wild, most predators can't get them when they're up in a tree, but there are more that can get them when they're on the ground. So even though she doesn't want to step up for you most of the time, she's willing to do it when it helps her get out of a situation where she doesn't feel comfortable.

She steps up when higher than me too though if she flys and lands somewhere other than her cage.

I say keep practicing
