That haunting call means your message has arrived. Wilderness delivery at its finest.

Population
roughly 600,000-640,000 mature individuals globally (rising to ~780,000 total birds including juveniles during fall migration); about 94% of the global population breeds in Canada
Habitat
Large, deep (oligotrophic to mesotrophic) freshwater lakes with clear water and abundant small fish for breeding, ranging from small single-pair lakes to huge lakes hosting 100+ pairs; winters on sheltered coastal marine waters, large bays, and some inland freshwater reservoirs
Fun fact
Common Loons have solid (rather than hollow) bones and heavy bodies that let them dive deep underwater in pursuit of fish, but the same weight means they need a long open-water runway to become airborne.
Range
Breeds across Canada, Alaska (excluding tundra), the northern contiguous United States, coastal Greenland, and Iceland; winters along the Atlantic and Pacific coasts of North America (Alaska to Baja/Gulf of California; Newfoundland to Florida/northern Gulf of Mexico) and in coastal Western Europe (North Sea, Celtic Sea, south to France and Spain)
Diet
Primarily fish (roughly 80% of diet, e.g. minnows, pike, perch, bass, trout), supplemented by crustaceans, mollusks, aquatic insect larvae, occasional frogs, and some aquatic vegetation
Size
0.81 m
Wingspan
1.36 m
Lifespan
25 years
