Amaze-wing Facts About The Common Loon For Kids

Discover great common loon facts here.

The common loon (Gavia immer) is one of the best diver birds to ever exist. Their incredible hunting prowess displayed while diving deep to hunt their prey underwater is a sight to behold which earns them the title of the 'great northern diver'. Their other name though, the 'common loon' is believed to have originated from their clumsy way of walking on land.

Even though they look like a duck in appearance, scientists have classified them separately from ducks. When it comes to classification, they belong to the order Gaviiformes, family Gaviidae, and genus Gavia. These species of birds have solid bones, unlike other birds that have hollow bones. These solid bones add to their weight, which in turn helps them with diving. Their legs are placed towards the back of their body which helps them with swimming in the water, but it also gives them their clumsy walking style. When it comes to swimming, they can deep dive up to 250 ft (76 m) in the water and can stay underwater for about five minutes. They usually catch small fish or shrimps which they swallow immediately, but they also bring the occasional larger catch up to the surface.

When it comes to the range of these birds, during the spring and summer seasons, common loons prefer to live around the North American and Canadian water bodies surrounded by forests as well as some parts of Greenland. For the common loon, winter marks the time for their migration. During winter, these North American birds migrate and settle around the north Atlantic and north-east Pacific coastal areas. Common loons from Canada and Greenland end up around the western European ocean coasts and waters. They also rest at the waters of the Great Lakes of North America during their winter migration.

When it comes to their life history, common loons are monogamous, having a single partner for life unless one of the adults dies, in which case they look for another partner. Nesting begins in the month of May and nesting sites are found on land spread across the shoreline. After breeding and a successful hatch, the parents return back to the same site the following year. According to the National Wildlife Federation, common loon populations are stable except for certain states in the U.S. where they are classified as threatened mostly due to human activity and climate changes.
