Tamarins are small, highly social New World monkeys. Their care in zoos demands sophisticated social management and rich environmental complexity to support good welfare.
Tamarin welfare in zoos depends on social complexity, environmental richness, and appropriate thermal management. These small primates have high metabolic rates and precise temperature requirements — inadequate warmth causes immediate welfare compromise. Social housing in family groups is essential — tamarins in pairs or solitary housing are deprived of the cooperative social structure their psychology requires. Vertical space and complexity are welfare requirements rather than optional enrichments for arboreal species. The Golden Lion Tamarin reintroduction success story shows that zoo populations can genuinely contribute to wild conservation when breeding and behavioral preparation are well-managed. Welfare assessment should include behavioral repertoire diversity and social interaction quality, not just physical health.
