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 #3 - REST ON A SANDBANK

American White Pelicans and Ring-billed Gulls, Mississippi River, Le Claire, Iowa

After a week of business travel it felt great to go out and enjoy nature and wildlife watching again. Yesterday’s trip along the Mississippi River led me all the way down to Le Claire, Iowa and up back north on the Illinois side to Savannah, followed by a short visit of the Green Island Wetlands on the Iowa side again.

Below lock & dam #14 in Le Claire these two American White Pelicans rested on a sandbank in company with a number of Ring-billed Gulls. They preened their feathers in the sun. It was quite a bit away from the shore and the 1.4x teleconverter was used to expand the focal length to 840 mm. People always debate the use of a teleconverter and claim it would degrade image quality. Except for the loss of light that hits the sensor (it becomes a f/9), I can’t confirm the loss of sharpness. The Nikon Z 600 f/6.3 works great with the TC-1.4x.

THE LONELY GUY

Greater Sandhill Crane, Mississippi Valley, Green Island Wetlands, Iowa

During yesterday’s trip to the Green Island Preserve I found only one Sandhill Crane. This is not really a surprise, we are stopover territory and most cranes breed further north and have probably moved on already. We do have some breeding pairs here in eastern Iowa but this bird had obviously no mate yet, maybe it is still a bit too young. Since I saw a Sandhill Crane already two month earlier in the same area I wonder if this is the same bird and it may have some impairment. I haven’t figured out that yet since I can’t be there every day to keep track.

Photographically it was the same approach as in yesterday’s image. The 1.4x teleconverter was employed and the camera was set to DX mode, delivering the same angle of view as a 1275 mm lens. I cropped the picture a little bit on the left and right hand side to keep more of the muddy mess around the bird out of the frame.

UNTIL THE LIGHT WAS GONE

Greater Yellowleg, Mississippi Valley, Green Island Wetlands, Iowa

The weather this week was not very pleasant, with temperatures around the freezing point, rain, even a little bit of snow, and almost no sun in the sky.This changed finally today and I could realize my plans going for some wildlife shooting to the Green Island Wetlands in the Mississippi Valley this evening. All the clouds disappeared and the best thing was that the air stayed relatively cool, means it was clear and the often feared heat shimmer above the surface of the wetland didn’t occur. With other words, great shooting conditions.

I saw lots of ducks, mostly Wood Ducks and Northern Shovelers, of course Canada Geese, Bald Eagles, the local Northern Harrier, and a small number of Tree Swallows. But the most exciting encounter were three Greater Yellowlegs. These migrating sandpipers were feeding in the shallow water at Green Island but they were quite a bit away. By attaching the 1.4x Teleconverter to the lens my focal length went up to 850 mm. This seemed still not close enough and I set the camera to ”crop mode”, which uses a smaller part of the sensor only, but gave me the equivalent of 1275 mm focal length. I thought without heat shimmer, as often present at this time of the year above the water surface, I can try it and had indeed quite a few sharp images.

Before driving back home I headed to the gravel road on the westside of the wetlands and found another Greater Yellowleg foraging in the water that covered the field below after the rain. The sun was setting behind me and the bird still searched for food and flew away only after all direct light was gone.

RETROSPECTS 2023 - #2

Red-headed Woodpecker

It was a thrill to watch a pair of Red-headed Woodpeckers working on the cavity in a tree trunk for their nest. It was my first time in spring at the Valley of Eden Bird Sanctuary over in Illinois, about an hour away from home. I really wanted to make this kind of image of a Red-headed Woodpecker since a very long time and all dreams came through this year. I wasn’t able to follow up on this later in the season, for example while the woodpeckers were feeding their offspring, but it is definitely on my list for 2024 to check out this great location again.

NATURE CLICKS #559 - EASTERN BLUEBIRD

This story started already last year, when I built a bird box that was especially designed for bluebirds. The Eastern Bluebird is a cavity nester that may use an old woodpecker hole in a tree or post but nest places became a hot commodity after more aggressive birds, like European Starlings and House Sparrows, became more widespread in the last century. Last year one of our House Wrens used the box for a nest. The bluebirds had no chance.

I photographed this male already while it came to one of our bird baths a few days ago and I became more excited when I saw it again yesterday flying into the entrance hole of the bird box with some nesting material. The nest is mainly built by the female but the males carry bits and pieces in and out of the box to attract a female. Once the female enters the box with the male the bond is established. I haven’t seen the female yet but my hope to have an active nest in this new bird box is growing.

Today’s photo was made right out of my office window on the second floor during the early evening. I had the 1.4 teleconverter between the Sigma 150-600 S and the camera and used the full focal length of 850 mm. The tree is across from the bird box, with some open space between, and the bluebird had obviously a good eye on it. He was cleaning his feathers after I made the first click and the bird gave me about 3 minutes to work with it.

NATURE CLICKS #550 - REDDISH EGRET

Reddish Egret, Bolsa Chica Ecological Reserve, Huntington Beach, California

Local people told me in the Bolsa Chica Ecological Reserve during my recent visit a couple weeks ago that three Reddish Egrets reside in the wetlands. I saw finally two of them and this one here presented itself in great side light. I always have seen the dark morph of this bird but a white morph exists also in other areas of the country.

If a body of water is between your camera and the bird and you have maxed out the focal length of your lens, in this case 600 mm, the only option to get closer is to use the teleconverter. I did that for the second photo with the Sigma APO 1.4x, which extends focal length to 850 mm, but finally still decided to crop both pictures a little.

NATURE CLICKS #541 - WHITE-BREASTED NUTHATCH

It was ideal weather today for spending some time in the “front yard studio”, with temperatures slightly above freezing. The sun was out and a very thin and hazy layer of clouds acted as a great light diffuser and in addition the snow on the ground worked as an additional light bouncer. I put the 1.4 Teleconverter on the lens and shot almost the whole time at 850 mm focal length. This allowed me to stay under the cover of our porch roof and the birds had less to worry about my presence.

One of the species I wanted to focus on was the White-breasted Nuthatch. The first image was made in the very early afternoon while the nuthatch posed briefly on this cedar stump. This adds some nice color contrast to the white, gray, and black of the bird and the crisp winter light.

Three hours later the setting sun added some warm light to the edge of our woods. It was a perfect setting for the typical “head down” of a White-breasted Nuthatch while moving down a tree trunk.

CARING BLUEBIRDS

Most of the time the parents call from different locations, either in nearby trees or from the top of the nest box. When both of them sat at this branch, it was only a question what bird to focus on. The female with an insect in its bill was the right choice.

The young Eastern Bluebirds in the nest box at my photography friend Kevin were almost ready to leave three days ago. I’m thankful that he called me and I still had a chance to take some pictures of the parent birds while they tried to lure the offspring out of the nest. Luckily they left not before the next day. It was a great setup with a small branch carefully placed not far from the nest box. Both parents waited sometimes several minutes with some food in their bill and quietly called the four nestlings.

The colorful male bluebird calls and lures with a little grub.

I used the 1.4 teleconverter, extending the focal length to 850 mm and allowing me to keep a safe distance to the nest. We did this last year at a different location in Kevin’s yard with the blue sky as a background. This year the green background of vegetation works actually much better for bluebirds and as a result I had a very high keeper rate. Thank you Kevin for arranging a great photo opportunity again!

The female is not as colorful but obviously found the bigger piece of food for the nestlings, a good size grasshopper.

WORKING WITH THE LADIES

Female Red-winged Blackbird, Mill Creek Ponds, Eastern Iowa

If we want to talk about one of the most common birds here in Iowa, at least during the season without snow, it has to be the Red-winged Blackbird. They are omnipresent wherever there is open space. The males arrive a lot earlier in spring from the south than the females and everybody here knows this black bird with its striking red bar bar on the wings that gave this bird obviously its name. You may not agree, but I’m always intrigued by the beauty of the female blackbirds, in particular during breeding season.

A couple days ago I stopped at the Mill Creek Ponds in a side valley of the Mississippi River. The long time followers of my blog may remember that I have photographed breeding Trumpeter Swans many times before at this location, but to my disappointment no swans seemed to be there this year. As always, the blackbirds have their habitat between the reeds of the wetlands and around the Mill Creek Ponds. Of course plenty of male birds are there and defend their territories aggressively.

I really focussed on the female birds this time and tried to incorporate the reeds along the pond in the background. I believe photographing a common bird should include a certain quality of light, otherwise I won’t publish it. 6PM is still way before sunset, but this valley receives the last warm sunlight for the day a lot earlier. While the first photo is all about the beautiful plumage of the blackbird lady, the second one is all about the gesture.

I try to make it a habit to shoot the long lens with the 1.4 SIGMA teleconverter attached. Having 850 mm focal length on a full frame sensor camera makes it very desirable for bird photography. Shooting a lot more with this tool lately, my keeper rate went up quite a bit. I can afford to be choosy about what image to use for a blog post…😉

INCUBATION TIME

House Wren guarding the nest

It’s breeding season for most of the birds in our woods. Many species incubate their eggs and are not seen as often as the weeks before during their mating time. We are very fortunate to have three different species sitting on eggs right here at the house. As during the last three years a pair of American Robins has built a nest on our balcony. They had originally four eggs, two didn’t make it, but two little chicks are currently fed by their parents. We avoid being on the balcony as much as possible.

The second bird is the Gray Catbird I reported about a few days ago. I discovered a nest today with two eggs. They built it between the branches of a mountain pine that grows right beside our porch. Another area we will try to avoid in order not to disturb the birds during incubation and the time after.

Last but not least, as every year a pair of House Wrens has occupied a nest box in our front yard and another female sits on eggs in another box at the back of the house. House Wrens are not monogamous and there is a good chance that the little male bird in today’s photos has something to do with the nest in the backyard as well. However, he tends and protects the bird box at the front. The wren sings his heart out, especially when the female has left the nest for a few minutes. He does that usually from a perch in the neighborhood, and not near the nest, so a possible predator will be attracted to him and not the clutch of eggs or the female while she is trying to find something to eat for herself.

I use this great photo opportunity and practice a lot with the long lens and teleconverter attached. The 850 mm focal length allows me to stay away as much as possible from the birds and still can fill the frame without cropping a single bit off.

NATURE CLICKS #520 - GRAY CATBIRD

Gray Catbird, Little Maquoketa River Valley, iowa

I’m very happy that we see a pair of Gray Catbirds near the house this spring. We always had them in the area but mostly not so close and frequently. They prefer low and dense vegetation and at another property in the neighborhood, where I used to see them, trees and bushes have been removed because a new house will be built. We don’t remove the underbrush in our woods and perhaps the catbirds figured out this would be a better place to live. I think the Gray Catbird is one of the most underrated birds. Most people recognize them by their distinctive “meeow-call”, which obviously gave the bird its name. However, they are also able to perform a song as a mix of notes, squeaks, and imitations of other birds. It sounds beautiful and I recently heard it again during time of courtship display.

I try to get better with my bird photography and have lately more often employed the 1.4x teleconverter when the distance to my subject was too far. This is my preferred method instead of cropping, but can be a challenge if light is very low. The long lens needs good support for its extended focal length of 850 mm, either a stabil tripod or proper handholding.

MORE TESTING, AND A COUPLE NOT SO COMMON BIRDS

Common Redpoll

We received more snow yesterday and snow removal took priority over photography. After a cold night the birds knew where to find food and water this morning and I decided to spent some time behind the camera and the glass of our balcony window. To make things even more awkward I put the 1.4 teleconverter onto the SIGMA 150-600, f/5-6.3 S lens. This was the first time that I used this piece of glass with the new Nikon Z6II mirrorless camera, extending the focal length to 850 mm. Let me talk about the performance first before we come to the birds. Even behind the double glass of the balcony door, the autofocus still worked fine at f/9 with the Sigma APO Teleconverter 1.4x EX DG. Yes, the pictures are a little soft, probably just due from behind the window glass, and it took higher ISO settings to nail the shots but it was doable.

Now, let’s talk about the birds. At this side of the house we have only a feeder with sunflower seeds hanging from the balcony. That draws in all the seed eaters, like cardinals, titmice, a couple Purple Finches, and dozens of House Finches, Dark-eyed Juncos, or American Goldfinches.

While shooting, testing, and looking at the results my excitement grew rapidly when I spotted a Common Redpoll. The only time we saw one before was seven years ago, right here on our balcony. They are actually an Arctic bird, breeding high up in the north of Canada. I just read that redpolls sleep in snow tunnels during a long arctic night to preserve body heat. Amazing! They migrate south for the winter but our area is even south of their usual winter range. However, I read reports about sightings here in Iowa every year. Not my best image but I know that some birders follow my website and I like to share my own bird sightings with them.

Yellow-rumped Warbler

The other bird I like to mention today is the Yellow-rumped Warbler. We still see between two and five females every day drinking at one of our bird baths, despite the very cold weather. They probably feed on the juniper berries that can be found here on top of the bluffs at he Little Maquoketa River Valley. The Yellow-rumped Warbler is capable of wintering further north than any other warbler. The photography, oh boy, I try really hard to make a picture without the bird bath in it. Do me a favor ladies, just jump onto the stone! 😉

GET IT RIGHT IN CAMERA (PART 2)

Although with a totally different aspect, I’m picking up from my last blog post today, “Get it right in camera”. All photos are from last weekend. Way too many times I do have to crop some of my wildlife images, mainly because of too much distance between the camera and the animal. There has been progress over the years but it remains a challenge and I’m not always up to it.

Well, there is a piece of gear in my bag that can help to get closer and fill the frame without cropping, but I admit, it hasn’t seen the light of the day much lately. I’m talking about the SIGMA 1.4 teleconverter that compliments the SIGMA 150-600, f5-6.3 and can extend its focal length from 600 mm to 850 mm. On a camera with a half size sensor or in DX mode on a full frame camera, like the Nikon D750, you can even get the angle of view of a 1,275 mm lens. Wow, this is a lot more than the naked lens can provide!

Of course there is a downside. With a maximum aperture of f/6.3 at 600 mm the SIGMA isn’t the fastest lens anyway, but with the teleconverter attached it becomes a f/9! This needs a lot of light for a good function of the autofocus system. But if the focus locks on, this lens / teleconverter combination delivers a sharp picture. It’s not the perfect solution for “low light” wildlife photography. But if the sun comes out and you have the great contrast, colors, and light this time of the season has to offer, you might be suddenly closer to your subject and after a while you don’t even know where the “crop-button” of your photo editing software is located…😉

IN THE FRONT YARD STUDIO

Female Purple Finch

As already mentioned in my last blog post, Sunday was a gray day but I spent some time in the “front yard studio” and practiced long lens shooting technique. We have lots of birds visiting our feeders with all the snow on the ground at the moment and I tried a few new things. Shooting directly from the front porch is not a valid approach right now. Sure, some “regulars” will still come close but the majority of our feathered friends stays away. I have the camera on tripod inside the bedroom (like in a blind) and since it was not as cold as earlier in January, the window was open. Because the window is 8-9 feet away from the edge of the porch I loose that much distance to my subjects, the little birds on one of the perch branches. To make up for that I attached the 1.4 teleconverter to the Sigma 150-600 S, which gives me an effective focal length of 850 mm. The best f-stop I can get is f/9 and that bares quite a challenge. The good thing is that the Sigma 1.4 and 150-600 S combination still works with autofocus, as long some contrast is provided to focus on. Both birds, the female Purple Finch and the Dark-eyed Junco have lines with contrast on their chest to lock on the focus. No, it doesn’t always work, autofocus is slow and the birds never stay long in the same spot.

Dark-eyed Junco

The rest is easy. I use the MAGMOD MagBeam flash extender to throw a hint of light at the birds in order to overcome the gray overcast and bring out their colors. The Nikon D750 is capable of separating the exposure compensation for the ambient light and for the flash and after a few tests I found the right combinations.

Junco: camera +0.33EV, flash -3EV

Finch: camera -0.33 EV, flash -3EV

Having the roof of the porch for most of the distance between camera and the birds has the advantage that the flash will not hit a lot of snow flakes if used during snow fall. I like to have falling snow in the picture but too much reflection can ruin the shot.
