Research Interests

Research activities related to the behaviour and ecology of birds, fish and mammals including studies of:
animal communication;
the biology of aggression;
animal welfare;
social factors influencing reproductive physiology;
conservation biology;
social recognition systems; and
the ontogeny of social behaviour.
