TWO WAYS

Fall colors in Backbone State Park, eastern Iowa

Although it was at the same location, in Iowa’s Backbone State Park, and the shots were made only a few minutes apart, each scene required a different way to tell a story. The road through the woods crosses Fenchel Creek several times, a tributary to the Maquoketa River and very popular for trout fishing. With the jam of leaves in the foreground and the beautiful colors of the maple in the back, I had to stop and capture the arrangements of nature.

Former trout hatchery, Backbone State Park

Ten minutes earlier I stopped at a former trout hatchery that was operated until 1987. It was constructed by the Civilian Conservation Corps (CCC) in the 1920s. The most visible remains of the hatchery are the circular ponds and this geometrical pattern triggered my desire to present the photo in black and white. No, I didn’t kill much of the fall colors, green dominates the scene, not just by the grass around the ponds, but the pines in the background hide most of the maples in the back. Well, the sky was just gray and I know a better picture can be made. A good reason to go back to the state park sometime soon…

TAKE IT NOW

Sunset over the Little Maquoketa Valley, eastern Iowa

This photo was made three days ago here in our woods and I’m pretty sure today it wouldn’t have turned out the same way. We had two very windy days and a lot of leaves came down and opened up the canopy quite a bit more. There is a lesson I learned some time ago and it was confirmed again with this shot, take the image now, when the light seems to be right, don’t wait for another chance with maybe even better light, it wouldn’t be the same, no matter what you do.

IN RUGGED TERRAIN

Upper part of the Pine Creek Unit in the Driftless Area National Wildlife Refuge.

It was a perfect fall day with sunshine and warm temperatures yesterday and as mentioned in my last blog post the leaves suddenly got the colors of autumn. I went out west to revisit a couple areas with unique features that make the Driftless Area standing out from most parts of the Midwest. First I hiked into the Pine Creek Unit of the Driftless Area National Wildlife Refuge near Colesburg, Iowa. I had scouted this location already in early June and wrote about it here in the blog. It was recommended as a good birding location and here is a link to my earlier post: https://exnerimages.net/blog/2025/6/1/scouted-a-new-location

White-crowned Sparrow

Most birds have migrated south already but I found a few White-crowned Sparrows feeding on berries and seeds in the brushes at the edge of the woods. Nothing says more about the season than having the bird perched next to some ripe berries in a bush almost bare of its leaves.

Rugged slope in the Pine Creek Valley

This time I wanted to get a little deeper into the area. The slope down to the pine creek valley is very rugged and there are no trails at all. Be forewarned, thick and thorny underbrush make it a challenge to hike with photo equipment! However, with the turning leaves and a little bit of sunshine you will see some beauty, hardly found in any other part of Iowa.

FINALLY SOME COLORS

A week ago I was asking myself, will we get any fall colors before most leaves are on the ground? It was still quite warm this week and many leaves just dried up and tumbled down. Well, all what it took was a few colder nights and a little bit of rain and everything changed quickly.

A short walk into the woods behind the house early this morning was worth the effort. The sun wasn’t out, but that turned out to be a good thing and allowed to capture the mood of this early morning with some fog between the trees. The polarizer was attached to the lens to take away any glare from the leaves and using the tripod allowed to shoot with ISO 100 for a minimum of noise introduction.

GONE SOUTH SINCE TWO WEEKS

You can tell where this bird got its name from

These two photos were made a month before I saw the last Ruby-throated Hummingbird during this year’s season at the feeders that hang at our porch or from a shepherd’s hook in the front yard. The final buzz from the wings of a migrating hummer was detected the last day in September this year. Nevertheless, we still left the feeders out until now. No reason to throw the sugar water that is used for hummingbird food away since many wasps used them still for feeding. Our pollinators are as important as the birds!

We only have this one species of hummingbirds here in Iowa and every nature lover who lives here will be happy to see them again at the end of April or during the first days of May next year.

I shot these images from a tripod and with just a hint of flash to reveal the bird’s colors during the late afternoon, and with limited natural light here in the woods.

NATURE CLICKS #614 - YELLOW-RUMPED WARBLERS

Yellow-rumped Warbler, Frenchtown County Park, Guttenberg, Iowa

A bunch of Yellow-rumped Warblers spent the Sunday afternoon feeding from berries (Bittersweet?) and cleaning their feathers at the banks of the Mississippi River in Frenchtown Park near Guttenberg, Iowa. The one in the first photo must have taken a bath in the river. His feathers were wet and the bird cleaned and dried them in the sun.

I was out practicing with a new piece of equipment I got as a gift last month, a monopod with a small gimbal head. I want to use it mainly for small bird photography in locations that are difficult to access with a heavier tripod. I will report about it in a later post sometime.

The small ramp at Frenchtown County Park is hardly used for boat access anymore. I have seen Yellow-rumped Warblers there before but was surprised how many were present this time.

SENSE OF FALL

Savannah Sparrow, Green Island, eastern Iowa

A big house project came to an end on Friday and I finally found the time to go out with the camera again and shoot some pictures. The photo above was made about 40 minutes before sunset at the edge of a field that was already harvested. The warm rim light on the dried up flower pods intrigued me and all the elements, including some spider web threads, give the photo of this sparrow a sense of fall.

Male Red-winged Blackbird, Green Island Wetlands

Thousands of Red-winged Blackbirds congregate in the wetlands along the Mississippi River at the moment and feed or rest during their migration to warmer areas in the south. If the winter is mild, as we had it during the last couple years, some of them will even stay here or at least return very early. I have photos in my picture library that were made in February.

END OF SUMMER THOUGHTS

Monarch, Mud Lake, Mississippi Valley, Iowa

Summer comes to an end slowly but surely and beside falling leaves from the trees many other indicators can tell the story about a changing season. Temperatures are still quite a bit above average but the number of flowers and butterflies is getting lower every day. I talked to some other nature friends recently and most said they have seen more Monarch butterflies this year then during the last couple years. However, the number of Monarchs have been in decline during recent decades and every trend in reverse is a sign of hope that this species may survive. I take every opportunity to make a click with the camera when I see a Monarch, hoping that this will never end.

BIRDS IN FLIGHT

Great Blue Heron, Green Island Wetlands, Mississippi Valley, Iowa

It was pretty quiet in the wetlands today, at least up to the moment when I was ready to leave in the late afternoon. Suddenly several hundred Canada Geese came across the Green Island wetlands in the Mississippi Valley and moved towards the low sitting sun in the west. They flew either in pairs or strings up to 25 birds for the next half hour. Communication with each other is obviously very important and the air was filled with their loud calls. I guess nobody gets excited here in the Midwest about Canada Geese, since they are present pretty much all year long, but many also migrate from up north, where food and open water are not available during the winter.

I saw this as a good opportunity to practice shooting birds in flight and walked with the camera and long lens onto a field to have a good view in all directions. I don’t know who was more surprised, the Great Blue Heron or I. The heron at least saw or heard me first and was already in the air when I discovered the bird. Sudden opportunities like this come and go very fast and it is exactly for these special moments why I practice handholding the long lens in order to come home with a sharp photo. The photos of the geese I made afterwards? Well, nothing but pure fun shooting pictures on a warm late summer day!

NATURE CLICKS #613 - RAPTOR WATCH 2025 - BROAD-WINGED HAWKS

Broad-winged Hawk, immature

Together with other members of the Dubuque Audubon Society I participated in the annual ”Raptor Watch” event in the Mines of Spain near Dubuque, Iowa today. I’m sorry for not posting anything lately, but other things in life required attention instead of wildlife photography last week.

Kettle of Broad-winged Hawks at the Mines of Spain, Dubuque, Iowa

It was great to be out again and have a camera strapped over my shoulder. In September large numbers of Broad-winged Hawks migrate to the northern part of South America and can bee seen in big flocks circling in kettles high up in the sky during migration. There are places in the Midwest where they have been seen by the thousands, but everybody on the small observation platform in the Mines of Spain was very happy to see several swirling kettles of 60-100 Broad-winged Hawks today.

My thanks goes to Tony Moline, a very knowledgable field guide as always, and all the other Audubon members that made this birding event a pleasant and great learning experience!

A BEAUTY IN THE SHADE

I don’t like if I walk through a week without having the time or chance to make a click with the camera. Last week was unfortunately one of it. Well, today I finally went out briefly into the great outdoors and made a few photos. This mushroom stood in the total shade of new tree growth on a dyke at Mud Lake Park. Expecting maybe to aim the lens at some bird, I had the Z 600 f/6.3 lens with the 1.4 teleconverter attached. Alright, this is not really a reason to walk back to the car for a different lens. So what, I put the belly on the ground and moved away from the subject beyond the minimum focal distance for the lens (~4m, ~13ft). So what is this shot about? I think it is the pure beauty of the mushroom, even if it is already in a state of decay. Nature can be beautiful sometimes beyond our imagination!

PEWEE VS. PHOEBE

Eastern Wood-Pewee, Mines of Spain, Dubuque, Iowa, Sep 06, 2025

Today I came across an Eastern Wood-Pewee while making a brief visit to the Mines of Spain Recreation area. Not an unusual sighting and these little flycatchers are not difficult to spot when they perch on a branch and dive down to catch insects midair or sometimes on the ground. They often return to the same perch, a fact every photographer may like.

Two weeks ago I photographed an Eastern Phoebe, right here in our woods, and that gives me the opportunity to show you how much alike these two flycatcher species look. So how to tell them apart? Here are a few details that may help.

  • The Eastern Phoebe has a dark bill, while pewees have a yellow or orange base of their lower mandible, which is very good visible in these two photos.

  • The Eastern Phoebe pumps its tail (the pewee doesn’t). That can help identification if you see for instance the bird just as a silhouette against the sky.

  • The two wing bars are less distinct on a phoebe, while they are almost white on a pewee.

  • And last but not least, if you hear the distinctive ”pee-ah-whee” song before you even see the bird, you certainly know that an Eastern Wood-Pewee is in the neighborhood.

TURKEYS IN THE NEIGHBORHOOD

Wild Turkey, Little Maquoketa Valley, eastern Iowa

It’s not unusual to see Wild Turkeys around here in the Little Maquoketa Valley, but most of the time they hardly present themselves for a photo opportunity. During last week a gang of four showed up several times on an open grassy spot right here on the bluffs above the valley.

I can’t see them from our house because it is below that particular location, but after seeing them for two days in a row while driving, I prepared myself already at home. Put the camera in my lap, had the car window down, and drove up the short distance to the top of the hill very slowly. A short stop, the turkeys were present again, and a short burst of shots from the car was all what it took to get the photo of this nice looking male turkey.

MISSISSIPPI RIVER STORIES 2025 #6 - ISLAND CITY ATTRACTIONS

Sabula, Island city in the Mississippi River

Sabula, Iowa’s only city located on an island in the Mississippi River, has two technical attractions I always like to look at. The first is their old-style water tower, which seems to be well maintained. If the sun is on the structure this tower stands out and can make for a nice reflection on the water. I have photographed it many times before but with the beautiful clouds we had during my last visit I could not resist to get the camera out again.

Sabula Railroad Bridge

The other interesting structure that connects Illinois and Iowa across the Mississippi River is the Sabula Rail Bridge, a large through truss swing bridge. This time I was there at the right time. After a few small boats had just passed, the bridge started moving and was swiveled back and ready for the next train to get over it. It only took a few minutes and my photo shows it about half way closed. The clouds again made this shot stand out for me.

GOING FOR A BIG SNACK

Great Egret with a catch, Mississippi River, Green Island Wetlands, Iowa

When you go since a long time and frequently to the same area for wildlife photography, as it is the Green Island Wetlands in the Mississippi Valley, you may start believing, I have seen it all, no big news anymore. But nature comes often up with a big surprise and I learned this lesson again a couple days ago. So here is the little story that surrounds the two photos in today’s blog post.

When I saw this Great Egret standing beside the gravel road in front of the car I didn’t even consider to make a click. An egret standing on the road and staring down the banks on the left hand side towards the lake wasn’t really a shot I was looking for. I approached the bird very slowly, even stopped, hoping it would take off and fly away before the car came close. Usually those egrets are quite skittish and don’t let you come really close. It took me a few seconds to realize that this guy was on to something and didn’t even look at me.

Suddenly the egret pushed its sharp bill into the weeds along the banks and jumped even down. Obviously it had made a catch. I expected seeing a little frog or maybe a locust in the birds bill, but surprisingly the catch was a lot bigger! This Great Egret had caught a young muskrat, one of the four-legged critters that live in the wetlands. While the bird ”handled” its prey, means it killed the muskrat, I asked myself, how is it going to eat that big snack? The critter didn’t move anymore when I shot the first image and the time stamp on my files revealed that seven seconds later the bird had swallowed the young muskrat completely. Nature can be brutal but as a wildlife photographer I try not to be biased. It was an amazing experience and I’m glad I had the camera in my lap and was ready to document the unexpected.
