Male Dominate Behavior During Breeding
One of the first signs of a male that is interested in breeding a female is his beard and chest area will turn a dark black and he will begin head-bobbing. Sometimes the head-bobbing will become so strong the male will actually be bouncing off the ground slapping his front feet on the ground. He will then let the female know he is going to attempt to breed her by "pecking" at her around the neck and the face. When a male attempts to breed a female he will grab her by the back of the head where there is a tough area of skin to hold on to at the base of the neck. This can be a violent act and can be considered "rape behavior" as the male will thrash about holding on to the female. The female gets handled very roughly so don't be surprised when you see a pair breeding. He will attempt to gain control and position the female so that he can breed her. He uses this method of holding the female down so he can get her into position. He will use his back feet and his tail to get the female to lift her tail in a way that he can insert his hemipenes to copulate.
