Each fall, the Mississippi River valley becomes a migration corridor for many species of waterfowl, raptors and shorebirds moving from their northern summer homes to warmer southern wintering grounds. One of the more spectacular birding opportunities in the southeastern Minnesota region is witnessing the impressive concentration of thousands of tundra swans in November at the Weaver Bottoms marshes of Winona County. Such great numbers of tundra swans only appear in this area on their route south.The best time to view the tundra swans is from mid-October through mid-November, Two viewing areas are at the Watchable Wildlife Observation Platform at Rieck's Lake Park near Alma, Wisconsin, and along Highway 61 near Weaver Minnesota. For further information about the swans at Rieck's Lake Park visit the Wings Over Alma website.
