Is this Normal?

[Karabear95]

My 3 month old sulcata will sometimes stretch his neck out and open his mouth (not wide) and bob his head slightly before returning to a normal position. he’s been doing this since I got him but I’m not seeing any other signs of Ri. Is he having trouble breathing? Is it normal? Thank you

I don't keep Sulcata. But to me it sounds like a threat display.
