Conservation status | Has disappeared from some former nesting areas owing to human disturbance on lakes in summer; acid rain may also reduce food supplies in breeding range. Has been protected on some breeding grounds in the northeast by volunteer "Loon Rangers" who patrol the lakes and help to educate the public about conservation. Projected to lose much of its breeding range as a result of climate change. |
---|---|
Family | Loons |
Habitat | Wooded lakes, tundra ponds, coastal waters. In summer mainly on lakes in coniferous forest zone, also beyond treeline onto open tundra. Chooses large lakes with ample room for takeoff and with good supply of small fish. In winter mainly on ocean, usually fairly shallow waters close to shore; also on large lakes and reservoirs that remain ice-free. |
Forages by diving and swimming underwater, propelled mainly by feet. Before diving, may swim on surface with head forward and partly submerged to peer underwater. Small fish swallowed underwater, larger items brought to surface and eaten there.
2, rarely just 1. Olive, spotted with brown or black. Incubation by both sexes (female may do more), 24-31 days. Young: Leave nest within 1 or 2 days after hatching, can dive and swim underwater at 2-3 days. Young are tended and fed by both parents; when small, sometimes ride on parents' backs. Capable of flight at about 10-11 weeks after hatching. One brood per year.

Mostly small fish. Includes fish up to about 10" long such as minnows, suckers, perch, gizzard shad, rock cod, killifish, many others. Also crustaceans, mollusks, aquatic insects, leeches, frogs. Sometimes aquatic plants such as pondweeds and algae.
Apparently first breeds at age of 2 years. Nesting territory claimed by "yodeling" song, also by flying in circles over territory with loud calls. In courtship displays, pairs dip bills in water repeatedly; rear up to vertical posture with wings partly spread; race side by side across surface of water. Nest: Built by both sexes. Site always very near water, on island or shore, partly hidden by surrounding vegetation. Nest, often re-used from year to year, is a mound of grasses, twigs, reeds.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.
Audubon joins a new coalition that aims to put Americans back to work while restoring the places that birds need.
The appropriations package provides important funding for ecosystem restoration projects, natural infrastructure, as well as western water and climate initiatives.
A new decision by an Atlantic Coast fishing regulator may put coastal birds like Ospreys at risk of not having enough to eat.
