Quantification of abnormal repetitive behaviour in captive European starlings (Sturnus vulgaris).
Stereotypies are repetitive, unvarying and goalless behaviour patterns that are often considered indicative of poor welfare in captive animals. Quantifying stereotypies can be difficult, particularly during the early stages of their development when behaviour is still flexible. We compared two methods for objectively quantifying the development of route-tracing stereotypies in caged starlings. ...
متن کاملLarger, enriched cages are associated with ‘optimistic’ response biases in captive European starlings (Sturnus vulgaris)
Anxious and depressed humans typically view circumstances more pessimistically than non-depressed individuals. Here, we explore the proposal that such cognitive biases also exist in non-human animals, and could be used as novel measures of animal welfare. Specifically, we test the hypothesis that wild-caught captive European starlings (Sturnus vulgaris) are more optimistic in their interpretati...
متن کاملEmbryonic modulation of maternal steroids in European starlings (Sturnus vulgaris).
In birds, maternally derived yolk steroids are a proposed mechanism by which females can adjust individual offspring phenotype to prevailing conditions. However, when interests of mother and offspring differ, parent-offspring conflict will arise and embryonic interests, not those of the mother, should drive offspring response to maternal steroids in eggs. Because of this potential conflict, we ...
متن کاملShape from shading in starlings (Sturnus vulgaris).
Birds behave as if they quickly and accurately perceive an object-filled visual world. Beyond the extensive research with pigeons, however, there is a large and important gap in our knowledge about the mechanisms of object perception and recognition in other avian visual systems. The pattern of shading reflected from the surfaces of objects is one important optical feature that provides fundame...
متن کاملDaily and seasonal variation in response to stress in captive starlings (Sturnus vulgaris): glucose.
We investigated the seasonal and daily variation in plasma glucose levels in response to stress in captive wild starlings. Starlings were captured from the wild during the winter, held on short days (11L:13D, mimicking winter), and then shifted to long days (19L:5D, mimicking summer). Birds were maintained on long days until they began a prebasic molt, the energetically costly replacement of fe...
