Effects of the presence of zoo visitors on zoo-housed little penguins (Eudyptula minor)

Abstract

Little penguins (Eudyptula minor), or Kororā in Māori, show variation in their behavioural responses towards zoo visitors in Australian zoos. We experimentally examined the effects of visitor presence on the behaviour and stress physiology of little penguins at Wellington Zoo, New Zealand. The two treatments were: (1) Visitor presence–the exhibit was open to visitors; and (2) Visitor absence–the exhibit was closed to visitors. We found that when the exhibit was closed to visitors, the percentage of penguins observed close to the visitor viewing pier increased from about 1% to 9%, but there was little effect on other behaviours and faecal glucocorticoid metabolite concentrations.
