FAQS on Waterbirds in Wisconsin

What is the large water bird in Wisconsin?

One of the large water birds frequently seen in Wisconsin is the American White Pelican. With a wingspan reaching over 9 feet, this pelican is easily recognizable by its pure white plumage and large, orange bill. During the summer months, it can often be spotted on Wisconsin’s lakes and rivers.

What kind of birds swim underwater in Wisconsin?

In Wisconsin, the Common Loon is a notable bird that swims underwater. Recognized by its black and white patterned plumage and haunting calls, the Common Loon is an adept diver, plunging below the water’s surface to catch fish. Another bird that dives underwater in the state is the Double-crested Cormorant, which can often be seen emerging from the water with a fish in its beak.

What is the rarest bird in Wisconsin?

The Kirtland’s Warbler is among the rarest birds in Wisconsin. This small songbird requires young jack pine forests for breeding, a habitat that has diminished over time due to fire suppression and land development. While the majority of its population breeds in Michigan, a smaller number nest in Wisconsin. Conservation efforts are ongoing to protect its specific habitat needs.

In Wisconsin, the diverse ecosystems offer habitats for various bird species, ranging from wading birds to small birds like the New World sparrows. Along the shores of Lake Michigan and in the wetlands of southern Wisconsin, wading birds forage in the shallows, while bald eagles soar overhead, their diets consisting mostly of fish. Interestingly, while Wisconsin hosts a variety of New World sparrows, it does not naturally house Old World sparrows, world quail, or world vultures. The state’s bird life truly reflects the richness of its landscapes, from the great lakeside to its interior forests and fields.
