Thousands of migrating birds have begun traveling through Wisconsin, with weather radar systems detecting significant flight activity across the southeast region. These arrivals follow a massive movement of avian populations southward to reach essential food sources.
Why it matters
Migration is driven by changing daylight hours and specific weather conditions like cold fronts and north winds, which allow birds to successfully navigate to warmer climates. Monitoring these movements provides critical insight into population health and environmental changes.
The Horicon Marsh, located in Dodge County, encompasses 33,000 acres of wetland that serves as a primary stopover for migrating birds. Approximately 200 pelicans were spotted at the site within the past week.
