Captivity may have adverse effects on captive great apes, as they spend much more of their time engaged in foraging and other activities in the wild. Enrichment interventions have the potential to alleviate the adverse effects of captivity by introducing novel stimuli. In orangutans (Pongo pygmaeus), interactive digital enrichment has proven effective at engaging users out of their own free will, in exchange for nothing but the experience. This article reports the results of scheduled visual enrichment in the form of “orangulas”—one-hour long videos of footage consisting mainly of open spaces in different environments, with which the pongid participant could engage at free will. The efficacy of the orangulas were measured with both behavioural and endocrine measurements, concluding that scheduled visual enrichment has the potential to improve the welfare of captive orangutans by providing novel stimuli in the context of largely stable environments.
