"Black-throated Loon," Wikipedia, the free encyclopedia. The Black-throated Loon (Gavia arctica) is a migratory aquatic bird found in the northern hemisphere. The species is known as an Arctic Loon in North America and the Black-throated Diver in Eurasia, its current name is a compromise proposed by the International Ornithological Committee. This species, like all divers, is a specialist fish-eater, catching its prey underwater. It flies with neck outstretched. It feeds on fish, insects, crustaceans and amphibians.The calls include a yodelling high-pitched wail and harsh growls, similar but lower pitched than Pacific Loon.
