Penguins in zoo settings face challenges around thermal management, water quality, and colony social needs that require expert design and management to maintain welfare.
Penguin welfare in captivity requires careful attention to species-specific thermal, social, and substrate requirements that vary substantially across the 18 species kept in zoos. Thermal mismanagement causes chronic physiological stress and disease. Foot problems from inappropriate substrates cause chronic pain. Colony housing with inappropriate sex ratios or group sizes prevents natural breeding behavior. The popular appeal of penguins in zoo settings must not allow visitor priorities to override welfare requirements including appropriate thermal environments that may require expensive climate control.
