Crust-like parts on sides of beak?

Hi all,

During the past two weeks, I’ve noticed a little crust-like place on both sides of our bird’s beak. Would appreciate some insight as to what this potentially could be, as I’d like to keep her as healthy as possible (i.e. do we need to go to the vet or am I being overly protective....)
Eating habits/patterns have not changed, nor has general behavior.

Thank you for any thoughts on this!
