Most northerly bottlenose dolphin population 'stable'
The world's most northerly resident population of bottlenose dolphins is "stable", according to new research.
Almost 200 dolphins are found in the North Sea and the animals are frequently seen in the Moray Firth.
Scottish Natural Heritage (SNH) commissions a report on the health of the population every six years.
Researchers from the University of Aberdeen, drawing on about two decades of studies, have deemed the numbers to be stable, or increasing.
The latest research work was carried out in the Moray Firth Special Area of Conservation (SAC).
Wildlife spotters who come to the shores of the firth to see and photograph the bottlenose dolphins contribute an estimated £4m to Scotland's economy a year, according to other work by the university.
