yawning

I would like to know if there are any other reasons for my BP yawning besides realigning his jaw last night he yawned for about ten seconds witch is the longest I"ve seen. And today he's doing it alot more then usual to but not as long. I put him in a new enclosure three weeks ago and he hasn't eaten yet so his jaw should be fine.:

BP's are known for randomly yawning quite a lot.

If it's happening all the time, that can be a sign of a respiratory infection.

Could be a possible RI, or it could be a stuck shed, or it's likely just nothing.

If they aren't showing any signs of RI (wheezing/popping, mucous in the mouth and surrounding area, etc) then it's probably just nothing. I don't know why they yawn, but they do.
