Environmental enrichment at Twycross Zoo, United Kingdom (1993)

Mason, A.

Abstract

The following outlines some of the many new designs for primates introduced over the past year... Our most successful feeder type has been a length of PVC drain pipe with holes cut into it. With this simple and inexpensive structure, many and varied designs can be assembled... In addition to puzzle feeders, efforts are made to introduce as much varied 'jungle gym' equipment as possible.
