how long do you have her out? she needs more toys alot of different foraging, noisy,things to make her cage a fun place to go. only feed her in the cage until you can build your bond and work on training. she is not trying to dominate you by landing on your head or shoulder she only wants to be with you. i get why you don't want her on your head but i'm curious about not wanting her on your shoulder? my

sits on mine all the time but my

is not allowed because she is to unpredictable and could take a nice chunk out of my face where if my

decides to get a little nippy not much harm done.so i trained my

to land on my arm instead with her favorite treats.i also have different perches around flight areas for them to land on. please don't grab your bird it's not good and could lead to behavior problems.
