MISSISSIPPI RIVER STORIES 2021 #10 - MIGRATION OF THE TUNDRA SWANS

Migrating Tundra Swans, Mississippi River, near Brownsville Minnesota

Right now one of the most interesting stories about fall migration happens here in the Mississippi Valley. Thousands of Tundra Swans migrate from the arctic tundra to the Chesepeake Bay at the Atlantic Ocean. On their way south they stop along the Mississippi River, and one of the best places to watch them is at a couple overlooks near Brownsville, Minnesota, just a few miles north of the Iowa border. The river is already freezing over in some of the backwaters. That means the swans may take off any day with more ice forming soon.

I have been at the Brownsville overlooks several times over the years with the camera and any time I ask myself, how can I tell a better story of this annual occurrence with my photos? It’s easy to take a wide angle lens, point it across the river, which is almost three miles wide at this place, and have thousands of wide dots in the picture. I do that for my own documentary purposes but those images do not make a good wildlife photo. 

So I try a little bit of everything, a single swan, a pair, or a family of Tundra Swans. It seems getting closer to a roosting place would help, but most of them are quite a bit away from the shore. On my way home I looked at a certain bay and got lucky. The bay was already frozen over and became a roosting place for the swans. With the sun disappearing fast behind the bluffs on our side of the river and the shadow line creeping forward across the ice, it was the right time to make a photo that tells a story about fall migration of the Tundra Swans.

NATURE CLICKS #481 - ROUGH-LEGGED HAWK

These are my lucky shots today. On my short trips to the Mississippi River during lunch break I drive quite often with the camera on the passenger seat or in my lap and look for wildlife. Rough-legged Hawks spend the summer up on the arctic tundra and come down to southern Canada and the U.S. for the winter time. Up north they feed mostly on lemmings and voles, while mice and other rodents are on their diet here during the winter. This hawk is a light morph but I have watched a dark form as well during the last two months only a couple miles away from this location. This Rough-legged Hawk is possibly an immature female but I’m not an expert enough to say that with certainty.

Rough-legged Hawk, near Sherrill, Iowa

She was perched on a utility post, a perch they like to hunt from. They need open habitats, such as fields or prairies. The procedure is always the same. I make sure nobody is behind me, slow down the car, roll the window down, take the hands off the steering wheel, grab the camera, stop the car, and start shooting. I have trained this many times on gravel roads without traffic but it still needs a bit of luck to get the picture. The hawk took off right before I came to a standstill but she flew towards me and I was able to fire five shots. I thought I missed the focus completely but later at home I found out that two shots were at least usable, although they are not tack-sharp.

It was not a first sighting of a Rough-legged Hawk, but I’m very happy because it was the first time I was able to come back with a picture that is more than just a documentary shot for the records. 

Both images: Nikon D750, Sigma 150-600mm / f5-6.3 DG OS HSM S, …@600 mm, 1/1600 s, f/8, ISO400. Shot in full frame mode (FX) but cropped in post to DX dimensions, which delivers an angle of view like with 900 mm focal length.
