This pilot study considers space use and behavior patterns for nine ch
impanzee mother-offspring pairs. Observations were conducted using ins
tantaneous scan sampling, four times daily, five days a week, for four
weeks. Mother-offspring use of vertical space and horizontal space an
d mother-offspring proximity were observed and analyzed using a Chi Sq
uare test. Results suggest mother-offspring pairs use levels above the
enclosure floor, spending a majority of time in areas near horizontal
bench substrates placed 1.2-2.5 m above the floor. Findings provide i
nformation that will assist managers in providing appropriate housing
for chimpanzee (Pan troglodytes) mothers and their offspring. (C) 1994
