Full Answer

Head-bobbing is typically seen in older bearded dragons that project dominance over younger dragons.

This signal is also directed towards smaller bearded dragons and females. To counteract the gesture, a subordinate dragon waves one of the forelimbs as a sign of submission, and females do the same to steer clear of aggressive males.

To mark the challenge, the head gesture is accompanied with flattening the body and puffing the throat. A dragon may also have a darkened beard when exhibiting dominant behavior or feeling threatened.
