Birds of Lake Superior

Lake Superior’s coastal areas are renowned for being prime bird habitats, thanks to the abundance of fish, wetlands, and forested regions. Birdwatchers visiting the area can expect to see a wide range of species, from majestic raptors to elusive shorebirds. The lake’s position along migratory routes also means that many birds pass through seasonally, adding to the diversity.

Common Loon

The iconic Common Loon is a symbol of northern wilderness and is often associated with Lake Superior. These birds are easily recognized by their striking black-and-white checkered plumage, red eyes, and haunting calls that echo across the water during the breeding season. Loons are expert divers, using their strong legs and webbed feet to catch fish underwater. They prefer quiet, undisturbed areas along the lake’s shores and large bays.

Bald Eagle

The Bald Eagle, a symbol of strength and freedom, is frequently spotted soaring above Lake Superior’s coastline or perched atop tall conifer trees. These large raptors primarily feed on fish, making the lake’s abundant fish populations ideal for their hunting needs. Bald Eagles build massive nests in tall trees near the water, and during winter months, they can often be seen congregating near open water where fish are accessible.

Great Blue Heron

With their elegant stature and slow, deliberate movements, Great Blue Herons are a common sight along Lake Superior’s shoreline and wetlands. These birds wade through shallow waters hunting for fish, amphibians, and small invertebrates. Their patience and stealth make them fascinating to watch, especially during early morning or twilight hours.

Ospreys

Ospreys, sometimes called fish hawks, are highly skilled hunters that rely almost exclusively on fish for their diet. They nest on tall poles, dead trees, or specially installed platforms near the water’s edge. Watching an osprey hover and then plunge feet-first into the lake to snatch a fish is a thrilling experience for any wildlife observer.

Additional Bird Species

  • Ring-billed Gulls: Commonly seen soaring over the water and scavenging along the shores.
  • Double-crested Cormorants: These dark water birds often perch on rocks drying their wings after diving for fish.
  • Pied-billed Grebes: Small, elusive waterbirds that dive swiftly to avoid predators.
  • Red-breasted Mergansers: Diving ducks frequently found in coastal bays.
  • Common Terns: Agile flyers that nest on sandy or rocky beaches.

Mammals Around Lake Superior

The extensive forests, wetlands, and river systems surrounding Lake Superior provide ideal habitats for many mammal species. The mixture of aquatic and terrestrial environments supports a diverse mammalian community, ranging from small rodents to large herbivores and carnivores.

White-Tailed Deer

White-tailed deer are abundant in the forested areas around Lake Superior’s shores. These adaptable animals thrive in mixed hardwood and coniferous forests, feeding on leaves, twigs, and acorns. Early morning and late evening are the best times to spot them grazing near the edges of the woods.

Beavers

Beavers are considered ecosystem engineers because of their ability to modify their environment by building dams, lodges, and canals. They are frequently found in streams, wetlands, and small lakes feeding on bark and aquatic plants. Their lodges, made of sticks and mud, are often visible along the shoreline, and the sound of their tail slaps can sometimes be heard at dusk.

Moose

Moose, the largest members of the deer family, inhabit the more remote and densely wooded parts of the Lake Superior region. These solitary giants prefer wetland areas and forest edges where they feed on aquatic vegetation and shrubs. Moose sightings along the lake’s coastal areas are less common but highly prized by wildlife watchers.

River Otters

North American river otters are playful and agile mammals frequently seen swimming, diving, and sliding along shorelines and riverbanks. They feed primarily on fish and amphibians and are indicators of healthy aquatic ecosystems. Their curious nature makes them a delight to observe, especially during the cooler months when they remain active.

Additional Mammal Species

  • Black Bears: Occasionally roam the forested regions near the lake, especially during berry season.
  • Red Foxes: Common in mixed habitats, often hunting small rodents near open areas.
  • Snowshoe Hares: Thrive in dense underbrush, changing coat color seasonally for camouflage.
  • Eastern Chipmunks: Frequently seen darting through forest floors and rocky outcrops.

Marine and Aquatic Life in Lake Superior

Though Lake Superior is a freshwater lake, its cold, deep, and oxygen-rich waters support a unique assemblage of fish and aquatic organisms. The lake’s ecosystem is complex and includes native species as well as some introduced ones, each playing vital roles in the aquatic food web.

Lake Trout

Lake trout are the apex predators of Lake Superior’s deep waters and are highly prized by anglers for their size and fighting ability. These fish prefer cold, oxygen-rich environments and feed on smaller fish such as ciscoes and whitefish. Conservation efforts have been important in maintaining their populations, as they were once severely impacted by overfishing and invasive species.

Whitefish

Lake Whitefish are an essential component of the lake’s food web and are important both ecologically and economically. These bottom feeders consume aquatic insects and small crustaceans, making them a key prey species for larger predatory fish. Whitefish also support commercial and recreational fisheries in the region.

Cisco (Lake Herring)

Ciscoes, or lake herring, are small, schooling fish that inhabit the open waters of Lake Superior. They serve as a crucial food source for larger fish such as lake trout and walleye. Cisco populations have fluctuated over the years due to environmental changes and invasive species impacts, but they remain a vital link in the aquatic ecosystem.

Sea Lampreys

Sea lampreys are parasitic jawless fish that invaded the Great Lakes through man-made waterways. They attach themselves to host fish and feed on their blood and body fluids, causing significant declines in native fish populations. Lake Superior has seen some control success through chemical treatments and barriers but continues to monitor these invasive species closely.

Other Notable Aquatic Species

  • Brook Trout: Native to tributary streams feeding into Lake Superior.
  • Smallmouth Bass: Introduced species that have established populations in warmer waters near the lake.
  • Freshwater Mussels: Filter feeders that contribute to water clarity and quality.
  • Crayfish: Important benthic organisms found in rocky and sandy substrates.

Amphibians and Reptiles

The wetlands, marshes, and forested areas around Lake Superior also support various amphibians and reptiles, which play crucial roles in the coastal ecosystem.

  • Wood Frogs: Known for their distinctive quacking call in springtime wetlands.
  • Green Frogs: Commonly heard near ponds and slow-moving streams.
  • Snapping Turtles: Large freshwater turtles that inhabit the lake’s calmer bays and wetlands.
  • Garter Snakes: Non-venomous snakes often found in meadows and forest edges.

Seasonal Wildlife Patterns and Migration
