Hebridean dolphins identified by their clicks

Previously, experts have distinguished white-beaked dolphins from Risso's dolphins by their whistles.

Hebridean Whale and Dolphin Trust used a technique called passive acoustic monitoring to record the clicks.

Scottish Natural Heritage said click studies could be an additional aid to indentifying the species.

HWDT correctly identified 90% of its encounters with white-beaked dolphins and 100% of Risso's from their clicks.

SNH has also suggested that further research could be done into how clicks might identify different groups of the animals.
