Come dine with me: food-associated social signalling in wild bottlenose dolphins (Tursiops truncatus)

摘要: Food-related signalling is widespread in the animal kingdom with some food-associated vocalizations considered functionally referential. Food calls can, however, vary greatly type of information they convey. Thus, there are a multitude purposes for which food used, including social recruitment, caller spacing, indication type, quantity, quality, divisibility food, caller's hunger level and even as tools to manipulate prey behaviour. Yet little work has focused on aspect calling animals. We investigated association signals wild bottlenose dolphins foraging behaviour where context-specific commonly produced. Our data showed that specific were significantly correlated call production these rarely occurred absence calls. suggest animals sharing additional patch itself their affiliates.
