Item Effects of different environmental enrichment items on the behavior of the endangered Lear's Macaw (Anodorhynchus leari, Psittacidae) at Belo Horizonte Zoo, Brazil.(2016) Azevedo, Cristiano Schetini de; Ramos, Júlia Caldeira; Faggioli, Ângela Bernadete; Cipreste, Cynthia FernandesEnvironmental enrichment is a technique applied to enhance welfare of captive animals by introducing items that create a complex and stimulate enclosure. In poor environments, animals can exhibit abnormal and stereotypic behaviors due to boredom and stress. Animals behaving normally and with high levels of welfare are suitable and preferred to participate in conservation efforts such as reintroductions. The aim of this study was to evaluate the effects of environmental enrichment items on the behavior of the endangered Lear's Macaws held at the Belo Horizonte Zoo, Brazil. Ninety hours of behavioral data were collected, divided into three equal-length treatments: baseline, enrichment and post-enrichment. Data were collected using focal sampling with instantaneous recordings every minute. Environmental enrichment decreased the expression of abnormal behaviors and increased macaw activities. Thus, environmental enrichment proved to be effective in the maintenance of normal behaviors and should be continually used to increase the welfare of Lear's Macaws.Item Using environmental enrichment to reduce the expression of abnormal behaviours in Greater rhea Rhea americana at Belo Horizonte Zoo.(2012) Azevedo, Cristiano Schetini de; Lima, Márcia Fontes Figueiredo; Cipreste, Cynthia Fernandes; Young, Robert John; Rodrigues, MarcosAnimals kept by zoos may express abnormal behaviours that are indicators of poor welfare. Environmental enrichment is a technique of providing items to animals that stimulate the expression of normal behaviours. The aim of this study was to evaluate the effects of providing simple environmental enrichment in the reduction of the expression of abnormal behaviour in captive-born Greater rhea Rhea americana at Belo Horizonte Zoo, south-eastern Brazil. As enrichment, fruit and vegetables were scatter fed to a group of seven birds from April to September 2009, and the behaviour of the birds was recorded using scan sampling with instantaneous recording of behaviour every 1 minute for 1 hour daily (90 hours of observation). The study was divided into three phases: baseline, enrichment and post-enrichment. The abnormal behaviours ‘pacing’, ‘eating faeces’ and ‘escaping behaviour’ reduced during the enrichment phase, but only the first two behaviours differed significantly between the phases; ‘walking’ and ‘foraging’, both positive behaviours, increased during the enrichment phase. These results showed that the implementation of simple environmental enrichment can stimulate the Greater rhea to exhibit more natural behaviours and improve their welfare.
