Nesting Swans
Scarborough Bluffs Conservation Area
Trumpeter Swans build their nests on a site surrounded by water and usually less than 600 feet from shore. The nest is usually built on an existing structure including muskrat and beaver dens, beaver dams, floating vegetation mats, small islands, or manmade platforms. Swan pairs often use the same nest site year after year.
Nest Description
Both sexes collect plant material to build the nest, which includes a foundation topped by a mound of aquatic vegetation, occasionally including grasses and sedges. The female uses her bill and body to shape a nest bowl atop the finished mound. The bowl’s lining may include a few feathers. Nests take 14 - 35 days to build and the completed oblong or circular nest mound can reach up to 11 feet across and 3 feet high, with a bowl measuring 10 - 16 inches across and 4 - 8 inches deep.
