Penguins are popular zoo animals whose welfare needs include cold temperatures, swimming space, and appropriate social housing. Meeting these needs requires specialist facilities.
Penguin welfare in zoo settings depends on appropriate temperature management, swimming access, and social housing. Species from temperate and sub-Antarctic regions suffer in warm climates without refrigerated facilities and access to cold water. Swimming space must be sufficient to allow the swimming speeds and distances that provide appropriate cardiovascular exercise. Penguins are highly social and colonial; isolation or very small groups cause behavioural abnormalities. Disease management is essential as the crowded conditions of zoo exhibits can facilitate transmission of the respiratory infections to which penguins are susceptible. Progressive facilities invest in large, cold, species-appropriate exhibits with colony-scale social groups.
