If you’ve been near Madison’s lakes in the last week or so, chances are, you’ve heard an loud screeching noise coming from the water. The culprit: hundreds of swans.
Each November and December, two swan species pass through Madison during their fall migration from the Alaskan and Canadian Arctic to Chesapeake Bay and the mid-Atlantic Coast. The length of their stay on Lake Mendota and Lake Monona depends on weather conditions and can range from days to weeks, according to Stanley Temple, the Beers-Bascom Professor Emeritus in Conservation at the University of Wisconsin-Madison.
As they travel, the swans make distinct vocalizations to defend territory, signal threats or communicate with family members, according to Sumner Matteson, a Madison-based avian ecologist. The two types of swans, trumpeter and tundra, each make distinct calls. Tundra swans, the more common of the two, have a high-pitched whistling call. Trumpeter swans, which were recently reintroduced to the Midwest through a recovery program, have a distinct trumpet-like call (hence the name).
To catch a glimpse of the swan swarm, Temple recommends Tenney Park or the Lakeshore Nature Preserve.
More than witnessing the absurdity of hundreds of loud swans in Madison’s lakes, Matteson says that seeing the birds can serve as an important reminder…
