Hiding from boats leaves less time for dolphins to feed

Description

A team of dolphin experts from Scotland have shed new light on the effect of marine tourism on the behaviour of dolphins. 

The team examined the impact of tour boats on the foraging efficiency of an endangered population of bottlenose dolphins off the coast of New Zealand. Their findings, published online in the Journal of Applied Ecology, suggest how the presence of these boats is reducing the dolphins' ability to feed themselves.
