Urgent Regurgitating(?) abnormally.

[ParrotK545]

My Parrotlet this morning made the regurgitating motion (odd head bob) so I know it's most likely not vomit, but when he regurgitated it came out as a foam?! No seed, no food- Foam... It's a saliva/mucus consistency. He's never regurgitated before (at least in my care), and I set up an appointment with a vet because that scared the jeepers out of me. But, until the appointment I wanted some feedback. Have you guys ever seen something like this before? Do you think it might be a crop infection?

He's eaten, drank and used the bathroom (normal appearance.)

Could be any number of things. Getting him to a vet is a great idea to rule out medical issues.
