Interesting Facts

  • The Red-throated Loon, also known as the Red-throated Diver, is the smallest and most widely distributed member of the loon family.
  • Unlike other loons, it does not carry its young on its back.
  • As recently as the 1800s, they were thought to be a foreteller of storms; birds flying inland or giving short cries predicted good weather, while those flying out to sea or giving long, wailing cries predicted rain.
  • A group of loons has many collective nouns, including an "asylum", "cry", "loomery", "raft", and "water dance" of loons.

● Foraging & Feeding: Red-throated Loon: Eats mostly fish; forages by diving from the surface and swimming underwater to pursue prey. Sometimes feeds in small flocks during winter.

● Breeding & nesting: Red-throated Loon: One to three olive green to brown eggs with black brown spots are laid in a ground nest made of grass, twigs, and mud, lined with finer materials, and built at the water's edge. Incubation ranges from 24 to 29 days and is carried out by both parents. Young start to fly at 49 to 60 days.

● Similar species: Red-throated Loon: Arctic and Pacific loons lack red throat patch in breeding plumage and show more contrast between dark nape and white throat in winter plumage.
