River and Stream Ecosystems

Here are two bird species that can be found in the river ecosystem. Each of these birds may be predators of the juvenile sturgeon swimming down the river.

Bald Eagle

Great Blue Heron (Ardea herodias)

Bald Eagle (Haliaeetus leucocephalus)

Bald eagles are well known as our national symbol. Bald eagles primarily feed on fish. Eagles scavenge dead fish along shorelines and capture live ones with their feet. Bald eagles are considered a threatened species in Michigan.

Great Blue Heron (Ardea herodias)

The Great Blue Heron uses its long legs to wade in the rivers and streams to catch fish. It may also eat frogs, mice, and insects. Herons can be seen along rivers and streams standing motionless, hunting for food.
