LOL, I know it is old, but the same thing happend here.
Silly macaw thinks it is a toy almost from day one: loves throwing the black whosname around and trying to take it apart, running after it, tugging it of my hand.
She saw me putting a blue one on the greys and decided that it must be something like her empty bottles (her favorite toy atm: the small cola/soda ones, because she can fling them far away, smack them in my face and throw them on her own back so she can scare herself...)
That is as far as I go for now with her- just wanted her to get used to the idea of harness...
It got worse than that... my other greys aviator is also black, so if I try to put his on-- she will protest: nobody can play with HER toy!!
