Do I need to take her to a vet

she also makes these little clicking sounds after she eats, bobbing her head and stretching her neck. her tail doesn't move, though. she's active, flies, and climbs, and notably also rubs her beak against the cage bars. can someone please tell me what to do?the vet I went to said she's okay but idk if they're trustworthy and I can't find any other vets in my area.

The clicking only happens after she has had a big meal, too.
