Because red-throated divers lie deep in the water, only their dark grey back of their body is visible. With their short webbed feet located close to their tail end, they are terrific swimmers and divers, catching and consuming their prey underwater. Only larger prey are carried to the surface. This bird was used for predicting the weather on the Shetlands: flying inland or short cries meant good weather; flying to sea or long cries predicted wet weather.
