Guinea Baboons.

When walking through dense forests a few times we were followed by a troop of baboons. Guinea Baboons as Mas our guide called them. These fierce looking animals are actually very shy, but hugely inquisitive. They would follow us, peeping through the vegetation from a distance of about fifty yards. They make a deep barking sound like a big dog when they get excited. They are nevertheless quite comical, so I made an effort to get a photo by peeping around a tree myself, trying not to spook them.
