getting the names of the skull bones].

back of the skull]
laterosphenoid ossification - a part of the inner skull, or brain

It is a type of mating behavior where males gather in a traditional
display ground and compete with one another by means of elaborate
display rituals to attract females. (Note, within the lek grounds
each male maintains a small seperate territory - there is little
or no direct confrontation between males). The lek display
often includes elaborate dancing, gaudy displays and loud noises.
The protypical example of this behavior is the prairie chicken.
[The display here involves fanning the tail, expanding a chest
cavity, dancing fast, and making odd sounds].
The peace of God be with you.
