NATURE CLICKS #607 - EASTERN MEADOW VOLE

Eastern Meadow Vole, Mud Lake Park, Mississippi River, Eastern Iowa

They look like a mini beaver without a flat tail with their thick fur, but this one was just the size of my fist. They are pretty common but still not seen very often by many people.

I was actually out for a certain bird species in the Mud Lake area along the Mississippi River but didn’t get the shots I had in mind. While walking on a new trail through an area of prairie vegetation that has been planted by the Dubuque County Conservation Board only a few years ago, I discovered this Meadow Vole. It didn’t seem to be bothered by me at all and continued chewing on fresh grass stems while I just walked by. The photo could have been made with any of my lenses but I had only the Nikkor Z600 , f/6.3 with me during this little exploration hike. For a picture like this the minimum focal distance of this lens of about 4 meters can become a disadvantage. It’s not difficult to get a sharp image, but I had to step back and at the end had to crop the photo to get you this intimate environmental portrait of this small critter.

MISSISSIPPI RIVER STORIES 2025 #4 - ON THE RIVER AGAIN

Spotted Sandpiper, Mississippi River, Mud Lake area

Yesterday morning I paddled into the main channel of the big river, following a Spotted Sandpiper that never seemed to stand still for a moment. The wind added some dynamic to the fast flowing water. I didn’t expect that the vegetation and probably some algae along the shore had such an impact on the colors reflected from the surface of the river, giving it a warm touch. Of course, I take that for a photo that is a little different…

RISKY PLEASURE

We made another paddle trip by kayak in the Mud Lake area on the Mississippi River yesterday evening. The water level of the big river was a little bit higher than two days earlier and as a result I saw only one sandpiper. But there is always something to find in this ever changing ecosystem of the Upper Mississippi Valley. Before we even saw them we heard the incredible noise from dozens of American Toads that had started their mating  time.

Having probably only one thing in mind some of the frogs didn’t pay the attention to their environment they should have. While I still tried to find the best position with my kayak, two Northern Water Snakes took advantage of the frogs desire for some pleasure and their drive to mate and snatched them off from the driftwood logs in the mud. One snake disappeared immediately in the water and made it to land quickly. The other one slipped over the log quickly and all what I got in my picture is the head of the snake and the legs of the toad sticking out of its mouth.

Well, this didn’t stop all the other males to continue to attract the females with their loud high-pitched trill. They produce their characteristic calls by using a combination of their lungs, vocal cords, and a vocal sac to amplify the sound.

Good time, good times!

NATURE CLICKS #604 - A SECRETIVE RAIL, THE SORA

Sora, Mississippi River, Mud Lake, Iowa

Shooting from a kayak leads to perspectives that are otherwise hard to obtain. I have photographed the very secretive Soras before from land and it seems they always disappear behind some reeds or bushes when you have them in the viewfinder. It can drive you crazy. However, the Sora is the most widespread and abundant rail in North America. While they search for food and move along the shore it is often hard to follow them. Being on the seaside in a boat makes it a lot more visible where they might go next and allows to predict a good opportunity for a shot a little bit ahead of time.

Soras rake often floating vegetation in the water with their feet or use their bill to move plant material and find insects, mollusks, snails, seeds or aquatic invertebrates. Yesterday I found three of these very beautiful rails in the backwaters of Mud Lake. The one in the picture below took actually a bath and frolicked in the shallow water for several minutes. What a show!

NATURE CLICKS #603 - DUNLINS ON THEIR WAY TO THE ARCTIC

Dunlins, Mississippi River, Mud Lake, Iowa

I really wanted to go back to the Mississippi River this afternoon and try to shoot from the kayak again. It was a good idea since I saw birds we haven’t spotted yesterday. The highlight were two Dunlins in full breeding plumage, who were definitely on their journey from the cost of the Gulf of Mexico or Florida to the arctic coast in Canada. This is a bird easy to identify with their black belly patch. They didn’t pay too much attention to my presence and didn’t stop to probe and jab in the shallow water or mud along the shore at Mud Lake on the Mississippi River. I have seen them a few times at the Green Island Wetlands further south during recent years, but always very far away. Today I finally had a real photo opportunity here in Iowa for the first time and I had a hard time to decide which photo to post here in the blog.

MISSISSIPPI RIVER STORIES 2025 #3 - OPENING THE SEASON

After taking many pictures of Greater Yellowlegs during this spring season I finally found a Lesser Yellowleg within the reach of the lens.

Today we used the nice weather with mild temperatures and sun and opened the paddle season. The kayaks were launched on the Mississippi River in the backwaters of Mud Lake, only a few minutes away from home. What was supposed to be a short trip became an all afternoon journey with lots of wildlife encounters. I have written here before how much I love to shoot from the kayak because of the ability to have the lens real low above the water, much better than driving by car on top of a dyke. Beside the usual suspects, like egrets, herons, geese, ducks, pelicans, and muskrats, we watched three different sandpiper species, a number of eagles, and even heard the Sandhill Cranes in the reeds.

Many Painted Turtles had climbed on driftwood logs and used the sun to warm up after a long winter season.

This adult Bald Eagle had just eaten something, probably a fish, and didn’t seem to be bothered by me drifting by with my kayak. Six or seven other eagles were nearby, maybe hoping to pick up some leftovers.

If this Solitary Sandpiper plans still to reach the breeding grounds in the northland regions of Canada, it better gets on its way for the rest of the long distance. They spend the winters from central Mexico to South America.

NATURE CLICKS #594 - DOUBLE-CRESTED CORMORANTS

Double-crested Cormorants, Mississippi River, Lower Sabula Lake, Iowa

While shooting birds on or in the water it is always recommended to have at least one eye in the air from time to time. Overhead flying birds are often a good opportunity I don’t want to miss, even if they approach suddenly.

Double-crested Cormorants are very fast flyers and I wanted to make a picture like this one since quite some time. With my heavy Sigma 150-600 S it seemed to be always a matter of luck to get a sharp shot. Panning with that heavy lens is not always easy.

While working with the pelicans you may have seen in my last blog post, four cormorants crossed the river and flew rapidly towards me. The exposure compensation was quickly changed by one stop (-0.67 to +0.33EV) to retain some detail in the birds plumage. The Nikon Nikkor Z 600 f/6.3, even in combination with the Z TC-1.4x teleconverter, is so much easier to handle while following birds in flight. I know for sure now why this lens made it in my gear locker.

COLLECTIVE EFFORTS

American White Pelicans, Mississippi River, Lower Sabula Lake, Iowa

It was so nice to see some colors again after a gray and nasty cold day yesterday. It was a good Sunday for checking out spring migration of the birds along the Mississippi again.

I have never seen so many pelicans fishing together before. This squadron contained more than a hundred birds, with many more on the water around, but choices had to be made what to leave in the frame and what not. First it looked and sounded like they all were fighting for the fish but pretty soon it was clear that it was a well organized collective effort by these American White Pelicans, as you can see in the second picture. I don’t know who was in charge to give the command, but suddenly they all took off and flew across the water to a different spot and started all over hunting for fish again.

MISSISSIPPI RIVER STORIES 2025 #2 - THE ICE MAKES SOME NOISE (VIDEO)

While shooting the photos of the Trumpeter Swans I showed in my last blog post I suddenly heard a crunching noise behind me, coming from the main channel of the river. A really huge ice floe had broken loose and started moving, grinding, and crashing against the rocks at the Potosi boat landing. We had a cold snap the night before and much of the Mississippi had frozen over again.

I like the crunching noise and hit the video button on the camera to capture the powerful movement of the river. Turn your speakers on loud, click the video below, and feel free to watch the little show.

This photo was shot later a few miles further south, giving you an idea how the ice got jammed above the lock and dam in Dubuque, IA, which is located but hardly visible at the horizon line.

ENJOYING THE TRUMPETERS

Trumpeter Swans, Mississippi River, Potosi, Wisconsin

I spent quite a bit of time on both sides of the mighty Mississippi River this weekend and like to share a some photos with you in the next few days.

This morning I saw about 25 Trumpeter Swans at the end of the John Deere dyke here on the Iowa side but all too far in the distance for a picture. A different scenario this afternoon at the Potosi boat landing on the Wisconsin side of the river, where close to 100 swans had congregated. Several family groups were feeding, resting, or socializing with each other and their loud trumpeting calls, that sound like a french horn, could not be missed.

Trumpeter Swans feed mostly with their head under water. I watched them today using their webbed feet to stir up roots. An adult swan eats up to 20 pounds (~10 kg) of food per day.

FUN AT #14 TODAY

American White Pelican, Mississippi River, near Le Claire, Iowa

With the temperatures becoming more moderate, just slightly below the freezing point, I thought it was a good time to go down south to lock & dam #14 near Le Claire, Iowa today. While the Mississippi River is still covered with ice for the most part up here, 90 miles further down the main channel had all open water.

While most people come here for watching Bald Eagles I was wondering what else could be found this time. Beside some other birds a large squadron of American White Pelicans owned the place and provided many photo opportunities and that’s what I like to offer today.

MISSISSIPPI RIVER STORIES 2025 #1 - BALD EAGLES

Adult Bald Eagle, Mississippi River, between Sabula, Iowa and Savannah, Illinois

A quick trip along the Mississippi River down to Green Island and Sabula this evening led to today’s photo. A couple Bald Eagles had perched in the dead trees along the road between the Sabula island and the bridge that crosses the main channel of the river over to Illinois. It was obvious that 600 mm focal length would not be enough to fill the frame with an eagle, but adding the Nikon Z1.4 teleconverter to the lens gave me 240 mm focal length more. I drove back to the birds with the side window down and the camera already in my lap. Made sure there was no car behind me, stopped briefly, and fired a number of shots until another car approached from behind. The light about an hour before sunset was just gorgeous for this kind of a shot. Back home at the computer I still thought I had a little bit too much ’wood’ in the frame and finally cropped the photo slightly.

Most of the Bald Eagle nests I saw today had already a pair of birds in or near the nest. It’s a big joy to see how this majestic bird bounced back from being almost extinct not that long ago.

MISSISSIPPI RIVER STORIES 2024 #6 - BACK TO BROWNSVILLE AGAIN

Juvenile Bald Eagle, Mississippi River, Brownsville, Minnesota

It was quite cold during the last nights and as a result the Mississippi River and all the other bodies of water started to freeze over, at least at places without much current. I had planned to go back up north to Brownsville, Minnesota again for the Tundra Swans but was wondering if the swans had taken off towards the Atlantic coast already. They will definitely do, if there is no access to food anymore due to an ice cover. Luckily my concerns were unfounded and this part of the river was not frozen over and several large schools, like the one in the picture below, were still present.

Tundra Swans on the Mississippi River. The main channel of the river is way back behind the islands at the Wisconsin side of the river, but the current of the water was still strong enough here to keep this part without an ice cover last Saturday.

I’m happy to witness this part of the great migration almost every year in November, even if the birds are too far out for a photo. Well, there are other things to look at and the most exciting were a large number of Bald Eagles. It’s always fun to watch how they chase each other after one gets a fish out of the water, drops it, and the game starts all over again. It takes a little patience because most of the hunting happens further away from the overlook, but I had my share of chances with the eagles within shooting range of the camera.

Canada Geese, Brownsville overlook, Mississippi River, Minnesota

I talked about it before already, shooting from an overlook and a bit above the water level leads not always to a desirable photo. However, it’s a good place to be if you have a flock of Canada Geese flying by and they honk at you at eye level. Great day, good times!

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”.

MISSISSIPPI RIVER STORIES 2024 #4 - PEACEFUL SUNSET

Sunset in the valley, Mississippi River, Abel-Essman Island, Guttenberg, Iowa

I really rushed down the hill into the Mississippi Valley, hoping to reach the outlook before the shadow of the bluffs would cover the island, on my way home last night. Just as I pulled into the parking lot beside the road the shadows already crept up on the west side of the island. When I jumped out of the car with the camera in hand a small airplane just took off from the landing strip between the buildings on Abel-Essman Island. Too bad, I missed that rare opportunity but I’m happy with this peaceful sunset scene in the river valley.
