Behavioural profile predicts dominance status in mountain chickadees, Poecile gambeli

TL;DR: An integrative theoretical framework is suggested that incorporates the tools that were developed to overcome similar methodological problems in psychology to facilitate a robust and unified approach in the study of animal personality.

TL;DR: It is concluded that problem solving is a valid experimental assay for studying innovation, a conceptual model of problem solving in which motor diversity plays a more central role than has been considered to date, and recommendations for future research using problem solving to investigate innovation are provided.

TL;DR: The overall conclusion is that chickens are just as cognitively, emotionally and socially complex as most other birds and mammals in many areas, and that there is a need for further noninvasive comparative behavioral research with chickens as well as a re-framing of current views about their intelligence.

TL;DR: The hypothesis that individual variation in competitive ability can be explained by alternative behavioural strategies can be supported by a study of great tits.

TL;DR: In this article, the authors examined whether individual coping characteristics of pigs were predictive of aggression during social encounters and the resulting social status and concluded that the coping style of pigs is related to their aggressive behaviour and the establishment of dominance relationships after mixing.

TL;DR: The hypothesis that subordinate mountain chickadees maintain elevated baseline corticosterone levels whereas lower caching rates and inferior cache retrieval efficiency might contribute to reduced survival of subordinates commonly found in food-caching parids is found to be wrong.

TL;DR: The results suggest that when in favourable foraging conditions, social interactions might cause dominant and subordinate birds to accumulate more energy reserves as a result of competition, and if food supply is limited, both dominants and subordinates may be forced to maintain similar fat reserves as an insurance against increased risk of starvation.

TL;DR: In this paper, the authors used chaffinches Fringilla coelebs temporarily held in captivity to determine the extent to which activity level (AL), behavioral response to a stressful situation (BRSS) and two anti-predation risk behaviours when exposed to a model predator were inter-correlated within individuals.
