The Sandhill Crane migration path in the U.S. includes the Baker Refuge northeast of Battle Creek, Michigan. Each year thousands of these enormous birds (4' tall, 6 - 7 ' wingspan) tarry for a while in a large, marshy lake. They have a very distinct call (youtube video to follow) and are an impressive sight as they all land within an hour-long time frame each evening. Bellevue, Michigan. 20 October 2007.
