Arctic loon

The most numerous wild bird species in the world

The Arctic (or Black-throated) diver is a larger counterpart to Pacific Loon with a bigger, thicker straight bill, white rear flank patch, and darker grey nape. They have noticeably thick white neck stripes, and the throat is black with bottom white underparts. Forage in reservoirs and large lakes; they prefer taiga and tundra lakes when breeding, while coastal bays and inshore waters for winters. Naturally live in E Siberia to W Alaska. The main diet is fish, but mollusks, crustaceans, aquatic insects, and small amounts of aquatic plants are also consumed.

Fishing nets, oil spills, acidification, heavy metal pollution, and wind farms are some reasons for the rapidly declining population.
