Whether dolphins behave differently between observation sites and towards specific types of watercraft are questions many researchers ask. This book (Volume III of III) outlines a study which investigated dolphin orientation, quadrant preference and swimming direction in relation to tour-boat presence at two New Zealand harbours. Individual and sequential beha-viour patterns were also investigated. The results obtained were compared to dolphin behaviour in the presence of a private yacht. Behaviours were cate-gorised as avoidance, positive or neutral behaviour. It was found that there were no...
