Demonstrations of nonhuman ability to share resources and reciprocate such sharing seem contingent upon the experimental paradigm used (note Horner et al. in PNAS 108:13847–13851, 2011). Here, such behaviour in Grey parrots (Psittacus erithacus) was tested in two experiments, both designed to avoid possible issues involving apparatus complexity, visible reward options, and physical competition and/or limited communication between subjects. In both studies, two birds, working in dyads, took turns in choosing one of four different coloured cups with differing outcomes: empty (null, nonrewarding), selfish (keeping reward for oneself), share (sharing a divisible reward), or giving (donating reward to other). In …

Qualitative Behaviour Assessment (QBA) is whole-animal methodology that assesses the expressive qualities of animal demeanour using descriptors such as ‘relaxed’, ‘anxious’ or ‘content’. This study aimed to examine the inter-observer reliability of 12 fixed-list QBA descriptors for sheep that had been generated in a previous Free-Choice Profiling study by experienced animal welfare inspectors, based on the same video footage used in the current study. The 12 QBA terms were scored by two different assessor groups consisting of two veterinary science students and four veterinary surgeons (Group 1), and seven farm assurance inspectors (Group 2). The two assessor groups met and …

Endurance horses are considered subject to a unique set of training and competing pressures due to the long distances travelled. The health and welfare of these horses could be compromised if they have not been adequately trained or are pushed beyond their limits, and there are increasing concerns regarding the capacity of horses to cope with the exercise demands placed on them, with high elimination rates for lameness and metabolic reasons. Veterinary inspections during these rides are important for assessing physiological measures, but the inclusion of behavioural assessments is also warranted. We investigated the application of Qualitative Behavioural Assessment (QBA) …
