:It is seen in mature males...kind of part of their courtship rituals. Have you seen him bob his head very rapidly...almost like vibrating it too? Sounds like simple mating behaviours to me. The pelvic dragging is often done in figure eight type patterns.
Hi John- Pelvic dragging...ok great name, yes he did do the figure eight thing but I have yet to see him bob his head up and down. I had a feeling he was starting the mating behaviour but I wasn't sure. Thanks for the insight. I'll keep you posted. More replies are welcomed. :)
