Free range exhibits are becoming increasingly popular in zoos as a means to enhance interaction between visitors and animals. However very little research exists on the impacts of visitors on animal behaviour and stress in free range exhibits.
We investigated the effects of visitor number on the behaviour and stress physiology of Kangaroo Island (KI) Kangaroos, Macropus fuliginosus fuliginosus, and Red Kangaroos, Macropus rufus, housed in two free range exhibits in Australian zoos. Behavioural observations were conducted on individual kangaroos at each site using instantaneous scan sampling to record activity (e.g., vigilance, foraging, resting) and distance from the visitor pathway. Individually identifiable faecal samples were collected at the end of each study day and analysed for faecal glucocorticoid metabolite (FGM) concentration.

Although their behaviour may not equate with some of the clichéd lifestyle changes associated with human midlife crises, a paper published recently in the Proceedings of the National Academy of Sciences suggests emotional highs and lows may also be an inherent characteristic in chimpanzees and orang-utans.
An international team that included scientists, zookeepers, and wildlife carers from the United States, Germany, Japan, Canada, Australia, Singapore, and the UK, used a four-item questionnaire, based on human subjective wellbeing measures but modified for use in non-human primates, to assess the level of contentment in 508 animals across a broad age range, and split into three groups. It was a decision made in a “burst of madness, since no study had ever been attempted,” according to economist Andrew Oswald from the UK’s University of Warwick, and a co-author of the report. He said the team was “just stunned” when results indicated the primates from all three groups showed evidence of experiencing a slump in wellbeing during their middle years.
The questions included measuring each animal’s moods, their enjoyment of social interaction, and success at achieving goals. Continue reading Crisis? What Crisis?
Veterinary groups have been highly critical of Victorian laws which led to two dogs being euthanased.
The dogs, named Bear and Kooda, were destroyed in June under Victoria’s new dangerous dog laws following a legal battle to save them.
The dogs had not engaged in antisocial behaviour, but were put down after an officer from Moira Shire Council identified them as pitbull crosses, despite the owners’ claim that they were bred from a Staffordshire-ridgeback cross and a bull mastiff cross American bulldog.
Victoria toughened its dog laws following the fatal mauling of a toddler last year.
The legislation has procedures for councils on how to identify pitbulls based on indicators such as build and head profile.
The RSPCA, AVA and ASAVA have expressed concerns that new laws could punish responsible dog owners, who follow the law and have their pit bull or pit bull crosses registered, and let irresponsible owners slip under the radar. Continue reading Outcry over new Victoria dog laws
