Insight: The Red-throated Diver (Gavia stellata) is the smallest UK diver, feeding mainly on salt- and fresh-water fish.
It’s breeding range extends from the Arctic tundra as far south as north-west Scotland and Ireland. During the winter it migrates south and may be seen around the UK coastline in estuaries and open sea, occasionally turning up on inland waters.
It derives its name from the distinctive deep red throat patch it acquires in summer. Also called Loons in Shetland, these birds are considered to be a reliable indicator of weather: short cries for fine weather or long mournful cries which eerily carry across the lochs for bad weather.
