What is the sound this cow is making?

Warning bark IMO. I've had a few cows do that to me just before shooting light and scare the crap out of me. Next thing i know the brush around me is being tore up cause there was a bull in the area. They watch each others backs just like we do.

   she didn't like what was going on but wasn't feeling real threatened. wind had to have been right and the camo was working, if you get this close just dropping out of sight will settle her down, maybe.

With deer in this situation I remain perfectly still and after about 4-5 mins, they forget what's going on and resume activity.  If you don't believe me, you haven't tried it   

I had a bull do this after he smelled me last September.  He ran into the thick stuff and kept doing it over and over again.
