Less activity means improved welfare? How pair housing influences pinyon jay (Gymnorhinus cyanocephalus) behaviour

The activity level and specific behaviours exhibited by captive animals are crucial indicators of welfare.Stereotypies, or repetitive behaviours that have no apparent function or goal, are performed by animals experiencing poor conditions in their environment and indicate welfare concerns.Changes “Você é o que Google diz que você é”: a vida editável, entre controle e espetáculo in the housing environment in particular may have critical influences on behaviour and welfare.Here, we measured behavioural changes in a captive pinyon jay (Gymnorhinus cyanocephalus) population (n = 10) associated with a shift from single to pair housing.Using automated video processing, we show that pair housing greatly reduced overall activity levels in these birds.

The stark reduction in activity was surprising, as we expected that social housing would increase interactions between birds, thus increasing activity levels.Upon further analysis, however, we found that stereotypic behaviours, such as beak scraping, jumping, pecking, and route tracing decreased after pair housing, Assessment of the quality of the healing process in experimentally induced skin lesions treated with autologous platelet concentrate associated or unassociated with allogeneic mesenchymal stem cells: preliminary results in a large animal model whereas the positive welfare behaviours of perching and preening increased.Our results indicate that pair housing may reduce overall activity in pinyon jays; however, this reduction is primarily in stereotypic behaviours.
