Breeds on small Arctic and subarctic lakes and ponds, then winters in bays, estuaries, and coastal seas.
It has a slim bill often held slightly upturned. Breeding adults show a gray head and reddish throat; winter birds are plainer.
It runs across water to take off and dives after fish. Pairs defend breeding lakes during the nesting season.
Small fish dominate the diet, with aquatic insects, crustaceans, and amphibians also taken.
Nests are placed low by water. Both parents incubate and bring small fish to the chicks.
Smaller than most loons, it often winters in shallow bays and estuaries. Oil pollution and fishing nets are important threats.
