Wisconsin Statewide Birding Report 4.23.12
Tundra Swans, formerly known as whistling swans, have been seen migrating through Wisconsin. Birders across the state have been reporting flights of them throughout the past one to two weeks as the birds move from wintering grounds in southern and eastern U.S. to breeding grounds in the Arctic tundra. Their primary spring route in Wisconsin appears to take them north along Lake Michigan and then north to northwest over Green Bay, inland through northeastern Wisconsin, then to Lake Superior and beyond. They fly in geese-like Vs and often make a short bark or whistle when in flight. Migrating loons were seen this week on Lake Monona in Dane County.
