Minnesota State Bird – Common Loon

Why Minnesota Chose the Common Loon

The Minnesota Legislature designated the Common Loon as state bird through official action. No other bird captures Minnesota's lake country character like the loon. Residents see and hear loons on lakes throughout the northern half of the state every summer. The bird's presence signals clean water and healthy ecosystems.

Schoolchildren across Minnesota supported the loon during the selection process. The choice reflected what Minnesotans valued about their natural heritage. Lakes define Minnesota geography, and loons define those lakes. You hear their calls at sunrise and sunset on thousands of water bodies. The bird already appeared in Minnesota artwork, postcards, and tourism materials before the official designation.

The loon beat out other candidates because of its unique connection to the state. Other states claimed cardinals or robins, but Minnesota wanted something distinctive. The Common Loon lived on Minnesota lakes for thousands of years before European settlement. Native peoples and early settlers both recognized the bird's special presence on northern waters.

History and Cultural Significance

  1. Legislative Action

    The state legislature passed the bill making the Common Loon official in 1961. Supporters argued that the loon represented Minnesota better than any other species. The bird already served as an unofficial symbol on tourism materials and local emblems. Public support for the designation came from across the state, particularly from communities near northern lakes.

  2. Native American Connections

    Ojibwe people called the loon 'maang' and considered it sacred. The bird appears in traditional stories and spiritual practices of tribes across the Great Lakes region. Dakota people also recognized the loon's importance in their territories. These cultural connections predate European settlement by centuries.

  3. Modern Recognition

    The Common Loon appears on Minnesota license plates, state quarter designs, and official documents. Sports teams use the bird as a mascot. Conservation organizations adopted the loon as their symbol for protecting Minnesota waters. The bird became shorthand for Minnesota identity in popular culture.

Symbolism and Meaning

Wilderness Character

The loon symbolizes untamed wilderness and clean water. You find loons only on lakes with healthy fish populations and clear water. The bird serves as an indicator species for environmental quality. When loons nest successfully, it signals that a lake ecosystem functions properly. Their presence means something remains wild and unspoiled.

Minnesota Identity

People identify the loon with Minnesota more than any other symbol. The bird appears on everything from coffee mugs to cabin decorations. Hearing a loon call triggers memories of summer vacations and lake life for many residents. The sound defines the Minnesota outdoors experience. Visitors remember the loon's voice long after leaving the state.

Conservation Values

Choosing the loon reflected Minnesota's commitment to protecting natural resources. The bird requires clean water, undisturbed shorelines, and healthy fish stocks. Supporting loon populations means preserving entire lake ecosystems. The state bird designation raised awareness about water quality issues and shoreline development impacts.

Physical Characteristics

Size and Build

The Common Loon measures 28 to 36 inches long with a wingspan reaching 51 inches. Adults weigh between 5.5 and 13 pounds, making them one of the heaviest flying birds in North America. Their solid bones help them dive deep underwater. The body sits low in the water, and the thick neck holds a dagger-shaped bill. Loons evolved for swimming, not walking on land.

Summer Plumage

Breeding adults wear striking black-and-white checkered patterns on their backs. The head and neck turn glossy black with an iridescent green sheen. A distinctive white necklace wraps around the throat. Red eyes stand out against the dark head feathers. This dramatic coloring appears from April through August during nesting season.

Winter Appearance

Loons lose their bold patterns after breeding season ends. Winter plumage shows gray-brown backs and white undersides. The distinctive checkerboard disappears completely. Young loons wear this duller coloring year-round until reaching breeding age at three years old. The red eyes remain visible even in winter plumage.

Behavior and Calls

Distinctive Vocalizations

The Common Loon produces four distinct calls that echo across Minnesota lakes. The wail sounds like a wolf howl and serves as a contact call between mates. The tremolo resembles maniacal laughter and signals alarm or stress. The yodel belongs only to males defending territory. The hoot provides quiet communication between family members. These calls carry up to three miles across water on calm nights.

Diving Abilities

Loons dive 200 feet deep to catch fish and stay underwater for several minutes. They swim using their feet, holding wings tight against their bodies. The solid bones add weight that helps them descend quickly. Loons catch perch, sunfish, and other prey fish underwater. They surface to swallow their catch before diving again.

Flight Patterns

Taking off requires a long running start across the water surface. Loons need 100 yards or more to become airborne on calm days. Once flying, they reach speeds up to 75 miles per hour. The birds fly with rapid, steady wingbeats and extended necks. They land by gliding down to water, never on solid ground.

Nesting Habits

Loon pairs build nests right at the water's edge on islands or protected shorelines. Both parents incubate one or two olive-colored eggs for about 28 days. Chicks swim within a day of hatching and ride on parents' backs. Young loons stay with adults for three months, learning to fish and avoid predators like eagles and large pike.

Habitat and Range

Breeding Territory

Common Loons nest on clear lakes across northern Minnesota from May through September. They prefer lakes larger than 50 acres with islands or undeveloped shorelines. The birds avoid lakes with heavy boat traffic or development. Each pair claims territory on a single lake and defends it against other loons. Minnesota hosts about 12,000 adult loons during breeding season, one of the largest populations in the continental United States.

Water Requirements

Loons need clean water with good visibility for hunting fish. They choose lakes at least 15 feet deep for diving. Acidic water from acid rain reduces fish populations and forces loons to leave. The birds require natural shorelines with emergent vegetation for nesting. Development, docks, and seawalls reduce suitable nesting habitat.

Migration Patterns

Minnesota loons migrate to Atlantic and Gulf coasts from October through March. They fly at night, navigating by stars. Adults leave first, followed by juveniles several weeks later. The birds spend winter on ocean waters, bays, and large coastal lakes. They return to Minnesota breeding lakes in April, often arriving while ice still covers portions of the water.

Year-Round Range

The Common Loon breeds across Canada, Alaska, and the northern United States. Small populations nest as far south as Wyoming and Montana. The species winters along both coasts from Alaska to Mexico and from Newfoundland to Texas. Minnesota represents the southern edge of prime breeding habitat in the Great Lakes region.

Interesting Facts

Fact 1 of 8

Loons cannot walk on land because their legs sit far back on their bodies. They push themselves along their bellies when moving between water and nest.
