Penguins in zoo settings require carefully designed swimming facilities that meet their behavioral and physiological needs, as swim access is central to penguin welfare.
For penguins, swimming is not optional enrichment but a core behavioral need. In the wild, penguins are superbly adapted aquatic hunters that spend much of their lives at sea. Captive settings that restrict swimming opportunities deny penguins the expression of fundamental natural behaviors, leading to frustration and stereotypic movement. Well-designed pools with appropriate depth, filtration, and social space, combined with terrestrial areas for nesting and resting, allow penguins to express their full behavioral repertoire. Regular welfare assessments should monitor swimming frequency, feather condition, and social behavior.
