Beak licking?

[LoveMyConlan]

My 1.5 year old Gcc, Conlan, has developed a weird habit I've never seen before. She's licking the sides of her beak, almost like a dog, though it seems like she only does this when she's excited or getting angry/flustered.

Is this normal Gcc behavior? She's never done it before but started about a month ago. Doesn't look like anything is stuck in her beak and only happens occasionally.

Not sure if it's the same thing, but Beau sticks his tongue out the sides of his beak, usually when he does certain whistles or warbles. I think it's an attention thing. He's usually excited or in a good mood when he does it.

Skittles will do this whenever I pour liquid. Its hilarious. He'll stick his tongue out and wag it.
