Rosella's body language gestures that confuse me

[OgY]

I have read certain articles about parrot body language. I'm not sure how to treat this one though: My rosella, when I stand by the cage and talk to her, she looks at me, turns her head, is relaxed, but has started to spread her tail. All other signals I interpret as her being interested and feeling good. Spreading the tail, which I've read is a sign of aggression, is a new sign and I'm not sure how to interpret it. How would you, the more experienced, interpret that new, additional sign ?
REgards,

My birds fan their tails when they’re happy to see me.

I can’t see the other body language your bird is doing but I’d wonder if she’s showing you how pretty she is because she’s happy.
