The relationship between social stress and dominance is seasonal in greylag geese
Article Abstract:
A non-invasive approach was used to explore the relationship between social stress and dominance in a sample of greylag geese, Anser anser. Single male geese had higher levels of cortisone than paired males during the mating season. In comparison, paired males had higher levels of cortisone than singletons and paired males without offspring during the parental season. These results suggested that social stress in these birds are caused by competition between males and limited access to females during the mating season. Dominance per se may not be a direct cause of stress.

Social learning in common ravens, Corvus corax
Article Abstract:
Research into whether the presence of a conspecific model can encourage the acquisition of a motor task in common ravens indicates that observational learning operates at a very finegrain level in ravens. It has been shown that ravens, which are regarded as being particularly intelligent, are able to obtain information about a specific motor task by looking at and interacting with a conspecific model. This finding may have significant implications for understanding the substantial ecological flexibility of ravens.
