Lumps in the mouth

[Aurora and I]

Her diet is good, she is on Harrison's adult bird food, she has a seed stick in her cage that she eats form time to time, and she gets fresh veggies in the mornings and evenings.
I think this is a good diet, but am not an expert
She is still looking healthy, and flies about a lot when out ov her cage ... so she's an active bird, with some signs of a respiratory infection.
I'm booking a checkup today at my local exotics vet.
