Effects of regulating visitor viewing proximity and the intensity of visitor behaviour on little penguin (Eudyptula minor) behaviour and welfare

Abstract

We examined the effects of regulating the viewing proximity of visitors and the intensity of visitor behaviour on behaviours indicative of fear and stress physiology of 15 zoo-housed little penguins (Eudyptula minor). A 2 × 2 factorial fully randomised design was used to examine the effects of regulating: 1) the viewing proximity of visitors to enclosure, ‘normal viewing distance’ and ’increased viewing distance’ (using a physical barrier set up 2 m away from the enclosure), and 2) the intensity of visitor behaviour, ‘unregulated visitor behaviour’ and ‘regulated visitor behaviour’ (using signage and uniformed personnel). In addition, a treatment consisting of closing the enclosure to visito..
