MISSISSIPPI RIVER STORIES 2024 #5 - TUNDRA SWAN MIGRATION, AND OTHERS

Tundra Swans, Mississippi River, Brownsville, Minnesota

One highlight for bird watchers in November is always the annual tundra swan migration on the Upper Mississippi Valley. Thousands of Tundra Swans make a stop near Brownsville, Minnesota just about 10 miles north of the Iowa border, on their way from the arctic to Chesapeake Bay at the Atlantic Ocean. They rest here before they finish the last 3000 miles to their destination.

I didn’t hold a camera in my hand for a week and was eager to take the two-hour trip up north today. I was a little stunned when only a few hundred swans were present, but the friendly Naturalist who was on site told me that we haven’t seen the peak yet. With other words, most Tundra Swans are still somewhere further north. She had a display table with lots of information about the swan migration, about the food they are looking for, like the starchy bulbs of arrowhead plants, and she answered the questions of many visitors.

Beside the Tundra Swans many other birds rest and feed in pool #8 of the Mississippi River and today’s little gallery can only show a few of them.

Gadwalls

Gadwalls were present in large numbers, probably several thousand, but I saw many other ducks, like American Wigeons, Northern Pintails, Mallards, Northern Shovelers, Ring-necked Ducks, Scaups, and Wood Ducks.

American White Pelicans

A large squadron of American White Pelicans socialized together on one of the islands nearby. They were joined by this group that landed in the water shortly after they made a flyby at the Brownsville overlook.

Trumpeter Swans

Trumpeter Swans can be found among the Tundra Swans. They are slightly larger and adults do not have the yellow spot at the base of their black bill. This family of Trumpeter Swans passed by at the Hwy26 overlook, a mile further south. Their calls are different and make it easy to distinguish between both species.

Northern Shovelers, New Albin, Iowa

This photo was made near New Albin, just at the Iowa-Minnesota border. Northern Shovelers are dabbling ducks and feed predominantly at the surface of the water. These five females had a feast and hardly stopped eating despite my presence. This was shot out of the car window, almost on eye level with the birds. The photos from the overlooks are made from a much higher vantage point and even cropping can’t prevent the not always desirable look of a ”bird from above”.

MIGRATING DUCKS

Northern Pintail / Mallard / American Coot -- Mississippi River, Deere Marsh, Iowa -------

Our area is kinda ‘fly-over-country’ for some of the ducks I show you today. Usually they spend the summer north of Iowa. The Mississippi River is an important flyway for their long travel.

It isn’t the first time that all three species used the pond at the Deere Marsh north of Dubuque, Iowa for food supply and rest during migration in spring. The Northern Pintail is easy to identify, even if someone is not so familiar with their color or pattern in the plumage. The long tail, much longer than on other ducks, tells the story, even if they have the head under water like the one in this image.

Gadwall

I watched several pairs of Gadwalls swimming and feeding by submerging the head in the muddy water. Part of the pond had a thin layer of ice but the Gadwalls had no problem finding food.

Ring-necked Duck

The Ring-necked Duck is a diving duck and feeds mainly on aquatic plants and seeds but also snaps at insects on the water surface. Their chestnut neck ring is often hard to see from further away but the white ring on their bill is a prominent field mark and makes identification relatively easy.

I used my car as a blind to get as close as possible to the ducks. At my slow arrival they all swam away from the shore but after a few minutes they came back within the range of the lens. Not as close as I would have liked and so I have cropped the photos a little.

NATURE CLICKS #269 - GADWALL (FIRST SIGHTING)

Nikon D300s, Sigma 50-500mm / f4.5-6.3 APO DG HSM           

I took a little detour on my way back from a business trip to Davenport, Iowa this evening and checked all the current “hot spots” in the Green Island Wetlands. I have by far not seen all the birds that come through the Mississippi Valley during migration and so it is not really a surprise, that even after living here now for more than ten years, I still have a first sighting of a new species once in a while.

Today I found a single male Gadwall foraging in the shallow waters of the wetlands. Well, it was not totally alone, it obviously enjoyed the company of several Northern Shovelers. At some point the Gadwall even made a courtship display for a female shoveler or it just tried to impress the males, I’m not sure…;-) The Gadwall is not an uncommon bird in North America, I just had not seen one yet before.

Photographically, this photo is not a master piece. The great looking duck was too far away with no chance for me to get closer, and so I decided to crop the picture a little bit.
