The only time they come ashore is to lay their eggs. All loons live in or around water, and they nest next to water bodies as well. 2, rarely just 1. A single brood is raised each year from a clutch of one or two olive-brown oval eggs with dark brown spots which are incubated for about 28 days by both parents. Incubation by both sexes (female may do more), 24-31 days. [107][108], In the 2016 Pixar movie Finding Dory, a somewhat bedraggled and dimwitted loon named Becky is persuaded to use a bucket to help two of the main characters, Nemo and Marlin, get into a marine life institute where the titular Dory is trapped. Common Loons are a classic bird of the North Woods lakes. [51] Significantly more nesting sites are found on islands than on mainland shoreline. The Common Loon population in New Hampshire is distributed throughout the state across a wide range of lake-specific habitats, water quality conditions, and levels of human disturbance. Status in Tennessee: The Common Loon is a common migrant and an uncommon but regular winter resident across the state. This long-term monitoring program has allowed for the analysis of patterns in the loons’ distribution. Nest, often re-used from year to year, is a mound of grasses, twigs, reeds. The Common Loon is a swimming and diving bird with a long body, short neck, somewhat blocky head with an angular forehead, and a long, dagger-like bill. [26], Fish account for about 80% of the diet of the common loon. The Common Loon is also the National Bird of Canada and the Provential Bird of Ontario, Canada.

Common loons can be common sights in both the treeless tundra and boreal forest regions of Canada where large, deep, open bodies of water are found. [62], The tremolo call—sometimes called the "laughing" call—is characterized by its short, wavering quality. [32] They appear in most of the inland waters of the United States. Habitat In Montana, Common Loons will not generally nest on lakes less than about 13 acres in size or over 5000 feet in elevation (Skaar 1990). Eyes are red-brown. The five species are Red-throated Loon Gavia stellata, Pacific Loon Gavia pacifica, Arctic Loon Gavia arctica, Yellow-billed Loon Gavia adamsii, and Common Loon Gavia immer.The Common Loon is the species best known to most of us, as its breeding range lies across most of Canada. Distinguish between living and nonliving components of a habitat. [20] In Ontario, 20 females averaged 4.5 kg (9.9 lb) and 20 males averaged 5.46 kg (12.0 lb). Common loons breed across most of Alaska and Canada, south to Washington, Montana, Minnesota, Wisconsin, Michigan, New York, and New England. The parent birds capture small fish and hold them crosswise in their bill, call and approach the chicks with their head lowered so that the chicks can grasp them. During flight, its head is slightly lower than its body, with its feet trailing behind. Common loons also suffer from hunting, predation, and water-level fluctuations, or flooding. Students at Brattleboro Union High School use art to channel both their climate grief and love for birds. Description. The estimated breeding population ranges from 1,400 to 2,600 mature individuals in Europe. [73] The black fly Simulium annulus is closely associated with the common loon to which it is attracted to chemicals in the uropygial gland secretions as well as by visual and tactile cues. [45] (Hence, most adult loons have two or more different mates during their lives.) The common loon is assessed as a species of least concern on the IUCN Red List of Endangered Species. Small islands are preferred for nesting, but herbaceous shoreline areas, especially promontories, are also selected. The frequency at which it vocalizes has been shown to vary based on time of day, weather, and season. Furthermore, males average up to nearly 27% more massive than females in some populations. Since loon monitoring began in 1976, populations have slowly increased due to conservation efforts. It’s the least you can do. The loon's diet consists almost entirely of fish. Its clumsiness on land is due to the legs being positioned at the rear of its body; the pelvic muscles are well developed,[39] ideal for swimming but not well-suited for walking. Forages by diving and swimming underwater, propelled mainly by feet. Bill is black and thick. 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. [79], The voice and appearance of the common loon has made it prominent in several Native American tales. [83] Juveniles had the lowest blood mercury concentration. Photo: Sunil Gopalan/Audubon Photography Awards. Common Loon (Gavia immer) A.O.U. Hunt Jr, G. L., Drew, G. S., Jahncke, J., & Piatt, J. F. (2005). In winter mainly on ocean, usually fairly shallow waters close to shore; also on large lakes and reservoirs that remain ice-free. [24] The bill colour and angle distinguish this species from the yellow-billed loon. [2], The scaly juvenile plumage is retained until January or February of the year following hatching, when a lengthy moult of head and body feathers gives them a more adult-like appearance. Because their nests are at the water's edge, common loon eggs are especially vulnerable if the adult is absent. Hence, the former group is exhibiting active preference for lakes that have been shown to result in higher chick mortality and lower breeding success. [83] Related to this information, it was discovered that mercury concentration differs by sex and age of common loons. [83], Elevated levels of mercury have been associated with changes in foraging as well as brooding behavior among adult common loons, especially in higher concentrations. Loons in western Canada and Alaska migrate to the Pacific Coast, from Alaska’s Aleutian Islands down past Mexico’s Baja Peninsula. The underparts are pure white, but have some black on the undertail coverts and vent. Loons winter along the coast and on open lakes nearby. Habitat: wetland . Hunting, along with habitat destruction, pushed loons … [57][58] Male parents defend broods consisting of two chicks more vigorously than singleton chicks, chiefly with the territorial yodel call. Its bill is heavier and the back is paler than its hindneck. [83] Although there have been reductions in recent years in acidifying emissions, there has been limited biological recovery in these lakes most likely due to climate change.
