Population statistics

Loons are several species of large water birds found in northern areas of North America and Eurasia.

Loons range in size between 25 and 34 inches long. They are normally grey or brown, except in the breeding season when the males of most species will sport feathers of deep black, flecked with white.

They mostly eat fish, and build their nests on the edge of the water, usually inland.

the cry of the Loon in summer is often cited as a representative feature of the far north.[1]
