Rehomed foamy beak grinding

[rebe]

I recently got my Alex x from a rehoming, (hatched 2018) and have noticed that when he grinds his beak (and only when he grinds his beak for a while) he gets an occasional foamy bubble while doing so

I'm not noticing any other symptoms of illness -his eyes, nose, and bum seem to be all clear

I've added photos of his poop, but as he is switching from a seed to pellet diet I'm not sure how much that may change his poop
(Top is older, bottom is fresh, all sunflower seeds were used as training treats not as main diet)

He's currently just moving onto a pellet diet, and gets fresh greens daily, with nuts/seeds as treats

Bump.

@Hankmacaw any ideas? I've only heard of Cape parrots naturally have spit bubbles since they are known to be droolers.
Have you asked your vet? I wonder if it maybe indicative of a crop infection?

I'm planning to take him to a vet once I find an avian one in my area- where I live parrots aren't popular pets and most places don't take parrots

This may be totally unrelated, but the only bird I've ever seen with saliva bubbles/stringy foam in beak, was a Umbrella Cockatoo that was dehydrated.
