A dog-faced lip-smacker

The acacia tree provides the perfect perch for this olive baboon (Papio anubis). He watches as his troop (numbering 100 or more!) pass by our truck in the Lake Manyara National Park, Tanzania.

“Boonies” are highly social creatures that live in large groups. The young learn skills for life while the mature battle for positions up and down the hierarchy.

The olive baboon gets its name from the color of his coat which appears green-grey. The anubis portion of its scientific name comes from the Egyptian god of the Underworld, often pictured with the dog-face that characterizes this species.


Baboons communicate using facial expressions and a variety of noises. They lip-smack, cough-bark, squeal, and scream. Adult males roar-grunt when on display! It can be a little scary.

If you are a church leader who is interested in leading a trip to the Bible Lands, I’d like to hear from you. I partner with faith-based groups to deliver outdoor academic experiences. Leaders receive the same perks that other agencies offer, at competitive prices and without the self-serving interests. I also promise to not to lip-smack or roar-grunt.
