    Conservation

    Conservation Low ConcernRed-throated Loon are found across North America, Europe, and some parts of the far east of Asia. The North American Waterbird Conservation Plan rates the species a 15 out of 20 on the Continental Concern Score and lists it as a Species of high Concern. North American populations are on the 2014 State of the Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action. Population declines have been noted in Europe, Alaska, and other parts of North America, but the reasons for decline are not well understood. Oil spills, degradation of habitat, and entanglement in fishing nets all pose threats to the Red-throated Loon. Back to top
