Just posting this for the ones that wanted to hear the growling sound!!!
This is not my vid...but one I have found on Arofanatics...hope it's ok
Turn your speakers high, and listen closely....about half way through the vid.....you'll see the larger male, do a quick shimmy, and then the growl/grunt....
I will try to post vids of mine soon.....
The grunt/growl in person is quick loud, and your able to hear it a few feet away....
I have also encountered different types of grunting from the male..
enjoy
