Dr Rick D'Eath is Reader in Animal Behaviour and Welfare at Scotland's Rural College (SRUC). As an applied ethologist working on farm animals, his main research interests involve understanding how the farmed environment can modify and sometimes frustrate an animals' motivated behaviours often leading to animal welfare problems. Rick primarily works on pigs and poultry, with a particular focus on questions around feeding and hunger, and interactions between animals which are negative for their welfare, including aggression, tail-biting and mounting.

His research was on poultry behaviour and welfare, focussing especially on specific appetites, laying behaviour, egg shell quality, feather pecking and housing systems. He headed the Ethology Department from 1988 to 1997 and was Institute Named Veterinary Surgeon and Chair of the Ethics Committee from 1993 to 2004. He was also a Tutor in the Open University on Biology, Brain and Behaviour and Lecturer on Edinburgh University's MSc course in Applied Animal Behaviour and Welfare. He was Editor of British Poultry Science from 1985 to 2010 and remains on the Editorial Board. Georgia Mason is a behavioural biologist a the University of Guelph, Canada, who studies how animals adapt (or fail to adapt) to captive housing conditions, especially conditions that meet their physiological needs but are too small or monotonous to allow natural behaviour. She is also interested in the validation of animal welfare indicators. (BA Biology, DPhil Ethology and Neurobiology) is a Professor of Animal Science and the Director of the Center for Animal Welfare at the University of California, Davis. She conducts research on the behaviour and welfare of poultry and small laboratory animals, with a particular emphasis on management and environmental enrichment. She serves on numerous national and international committees and boards that address issues related to farm and laboratory animal welfare, and teaches courses on animal welfare and animal ethics. Michael Mendl is a Professor of Animal Behaviour and Welfare at Bristol Veterinary School. His research interests are in the area of animal behaviour and welfare, particularly the links between affective and cognitive processes, and the ways in which attention, memory and decision-making both influence and are influenced by affective state. He is also interested in the evolution and function of affective states, developing new measures of animal emotion and welfare that can be used under field conditions (including automated / machine learning), and understanding more about animal cognition, emotion, personality, and social behaviour with a view to identifying and minimising welfare problems for captive animals. Ruth C. Newberry is a Professor of Ethology in the Faculty of Biosciences at the Norwegian University of Life Sciences. Her early years were spent on a farm near Ottawa, which had a resident cat colony. Before the cats were neutered, she saw first-hand the communal nursing of Tinkerbell and her adult daughter, and the comings and goings of the resident tomcat. As a zoology student at the University of Edinburgh, she was encouraged by Jane Goodall's writings to pursue the study of animal behaviour, leading to her PhD research in the Edinburgh Pig Park observing communal nursing in pig nests. After several years investigating chicken behaviour at the Agassiz Research Station in British Columbia, she journeyed south to join Washington State University's colleges of veterinary medicine and agriculture. There, she conducted studies on a wide range of animals including cats. Having finally habituated to cowboy hats in her classroom, the northern lights beckoned once more, this time to Norway. Here, since 2013, her research has focused on methods of environmental enrichment that foster harmonious social development and positive welfare. Ruth is a Past-President and Honorary Fellow of the International Society for Applied Ethology, and a member of several scientific advisory committees on animal welfare. A confirmed cat person meeting the personality traits described in Chapter 12, she has shared her home with a succession of beloved cats, Annapurra Katman, Cinnamon Daintree, Siena Kitkatla to name a few, whose unique personalities have provided inspiration during the writing of this book. Birte Nielsen is an applied ethologist currently working as Assistant Scientific Director at UFAW (Universities Federation for Animal Welfare) and their sister-charity HSA (Humane Slaughter Association). She has previously worked at the National Institute of Agricultural Research (INRA) in France and Aarhus University, Denmark. Her research has spanned the science of olfaction, studying the behavioural responses of rats to different smells, and feeding behaviour in ruminants. Birte has in-depth experience in experimental behaviour science on rats, growing pigs, dairy cows, broiler chickens and broiler breeders, and has been actively involved in work on horses, sows, laying hens and even ostriches.

Dr Sally Sherwen is the Director of Wildlife Conservation and Science at Zoos Victoria (the Conservation Organisation charged with the operation of Melbourne Zoo, Werribee Open Range Zoo and Healesville Sanctuary in Australia). Sally leads a dynamic team of scientists and specialists that develop and deliver strategic programs in conservation, animal welfare, education and environmental sustainability. Sally has a PhD in Animal Welfare Science and in previous roles has established an evidence-based research program in animal behaviour and welfare science, developed and implemented an institutional welfare assessment tool to advance welfare standards and designed and ran collaborative training courses with several NGOs for industry professionals and community groups. Francoise is a Senior Researcher at SRUC, and her main research interest is the development of scientific approaches for the study of animals as whole sentient beings (i.e. as subjects rather than objects), bringing insights from philosophy of mind and social psychology and anthropology into the study of animal emotion. In collaboration with colleagues from SRUC and other institutes, Francoise has developed and validated a methodology for the study of animal expressivity (body language) and subjective experience, generally referred to as 'Qualitative Behaviour Assessment' (QBA). Her research focuses on the application of this method as a practical tool for welfare assessment and management in farm, zoo, and companion animals. Research interests associated with this work are animal boredom and environmental enrichment.
