Chatfield, J. J. 1990. Notes on the introduction of an aggressive male gorilla at the Los Angeles Zoo. Proceedings: Columbus Zoo Gorilla Workshop, 2-4.

The integration of a conspicuously aggressive adult gorilla into an established group of young animals plus one adult female is described. The introduction took close to two years and lots of patience and effort. The end result proved that is was all worthwhile and certainly the risks [bite wound inflicted on the adult female requiring surgery] were justified. The male was tolerant toward the young animals.
