[LeopardLass"]Yes those are baboon warning "barks" or calls. they do it when danger is near. Here's a video you can watch taken a while back from Nkorho where the baboons are warning of the lions presence.
I just read that they are asking us not to use You Tube anymore because it is not safe for the school kids. I can't say anything because I didn't down load the program yet to capture video or pictures so was wondering if anyone can point me in the right direction for when I do. You tube has easy access to porn and things that are not suitable for school kids.
