I can't say Shade is much trouble - in fact, she's one of the best behaved birds in the flock. However, once in a while, she flies and lands on thing she shouldn't be going to - and is doing this purposefully.
Such as going on the vent in the orange room. Not sure why she is fascinated by it, but it is not something we encourage as she seems to have a hard time leaving that spot on her own and it's always tricky to get her off with a perch.
She knows she shouldn't be going there, but every few months, she'll give it a try.
