Penguins in zoos face specific welfare challenges related to thermoregulation, moult, social structure, and the need for swimming opportunities appropriate to their natural behaviour.
Penguin welfare in zoos depends on species-appropriate temperature ranges, adequate swimming facilities, appropriate social group sizes, and correct substrate to prevent foot disease. Facilities housing cold-adapted species in warm climates require significant climate control investment. The annual moult creates a welfare-sensitive period when birds are vulnerable to thermal stress and reduced immunity. Bumblefoot from inappropriate substrates can progress to severe lameness and systemic infection without management. Best practice zoos provide large pools, natural substrate, species-appropriate climate control, and social groups of sufficient size to allow natural colony dynamics.
