Studies in the Wild

No scientists have been successful in a long-term study of a drill group in the wild - this means that very little information exists on wild behavior.  Only two scientists; Steve Gartlan (a study in the 1970s) and more recently, Christos Astara in Korup National Park have managed to follow wild drills for short periods of time through the forest and have published what information they learned (see the 'further reading' section below).  A number of surveys in drill range have documented the status of drills in parts of the forest (see 'further reading' below).  At the Pandrillus Drill Rehabilitation and Breeding Center in Nigeria, where drills live in enclosed natural habitat forests, a large volume of information about life-history, behavior and reproduction in the large social groups of drills found there was the subject of Dr. K.L. Wood's (of Tengwood.org's) dissertation, and is available for purchase here.
