Beautiful Tundra Swans

Mr. Science and I headed down to the "Big River", the Mississippi, yesterday for a day of birding. There, the Mississippi National Wildlife Refuge provides a safe haven for millions of migratiing waterfowl each fall. We did, however, have a special target in mind. Migrating from their summer breeding grounds in the northern Arctic, tens of thousands of beautiful large white birds, wend there way south to stop, rest, and refuel on the Mississippi River near Brownsville, Minnesota. They pause here, usually for a few weeks, before turning southeast, heading for their wintering grounds on Chesapeake Bay. They are the beautiful Tundra Swans.

Here, on a backwater near Weaver, we see hundreds of swans and ducks. In the distance, beyond the screen of trees, a barge is moving down the main channel of the river. With Wisconsin in the distance, perhaps a mile away, we can see many more. Sometimes, huge "rafts" of these birds seem to turn the entire river white. When we step out of car, the sound of their vocalizations is almost deafening. Some are even close enough to us to get a picture. On occasion a few fly over us, but I'm not a skilled enough photographer to get a decent picture. Another wonder can occur; on some visits I've counted well over several hundred Bald Eagles. If the sun is out and thermals rise above the bluffs, we can see them "kettle." They form a spiral rising almost out of sight. Late migrating white pelicans also use this river highway. Awkward looking on the ground, they are magnificent soaring aloft as they head south to the Gulf.

With the construction of the lock and dam system on the river in the 1930's, many of the natural aspects of the river have changed. One of these is the wave action of the increased open spaces. Many islands have disappeared. Because of this many of the plants and tubers the swans fed on have also disappeared. Now man is undoing the damage and helping the birds by using dredge material from the main channel to rebuild these islands. Here you can see one of the many artificial islands providing a resting place and shelter from the wind and renewed food supplies. Way to go DNR and Army Corps of Engineers!

I took a video with my little point and shoot camera, I wanted to let you hear the swans. I estimated their were about 5,000 in the immediate area. There have been well over 100,000 during peak weeks of the migration. Unfortunately, Blogger didn't like it.
Darn!
