CHECKING THE GRASSLANDS

Male Bobolink, Technology Park, Dubuque, Iowa

Hard to believe it has been a month ago that I photographed Bobolinks in the grassland patches at Dubuque’s Technology Park south of the city. Despite the heat and humidity I spent almost an hour in this area yesterday afternoon and saw at least half a dozen male Bobolinks. Most of the time they were too far away for any consideration of a picture but the one I can present today didn’t mind my presence at the edge of the field, came close, and continued feeding in the grass.

Male Red-winged Blackbird

Here in the Midwest of the US most people don’t think too much about the Red-winged Blackbirds because they are here in abundance for most part of the year. The sighting of a blackbird in late winter is often seen as a sure sign that spring is not very far. During the last few years, with its mild winters and a change in climate, I have seen them even in January in certain places here in eastern Iowa. With a bird in abundance it’s easy to forget how pretty these birds really are. They are very adaptable to their environment and any time a strip of grass is available, either along the roads or just like here in the meadows of an urban area, the loud noise of their calls is in the air.

BUSY PURPLE MARTINS

Male Purple Martin, Mississippi River, Mud Lake, Iowa

I still have a few photos from our recent trip to Minnesota but today I like to share some actual pictures that were made yesterday. I had received an information about the current breeding activities of the Purple Martins (Thank you Mike!) and went down to Mud Lake at the Mississippi River. Three days ago both breeding towers had more than 75 eggs and almost 30 nestlings had hatched already. The parents were very busy to feed and to guard each nesting chamber. I believe each tower holds 18 chambers.

Female with her latest catch at the martin house

I have plenty of pictures with martins sitting at the entrance of a nest box but I really wanted some shots with a bird in flight, approaching the nest or just hovering in front of it.

However, the second image shows a female with a dragon fly in its bill and waiting in front of the entrance hole of her nest. It took about four minutes before she turned around and entered the box to feed the offspring.

If you are not familiar with the habits and biology of our largest swallow, you can find a lot of information about these birds on the websites of the CornellLab or the Purple Martin Conservation Association.

The Purple Martin is a very interesting bird and it is fun to watch how they catch all their food in flight and get their drinks by scooping water from the surface of the river or pond with their lower bill.

NATURE CLICKS #610 - RED-NECKED GREBE (FIRST SIGHTING)

A pair of Red-necked Grebes with two juveniles, Star Lake, Ottertail County, Minnesota

Remember, in my last blog post I mentioned a ”few surprising moments” during our last paddle trip in Minnesota a week ago. Here is the second one. When I came slowly around a bend in the canal between the reeds into a little more open space, I immediately recognized a bird species I had never seen before, a pair of Red-necked Grebes with two juveniles. While some of the clicks I made just a few seconds earlier showed the young one behind the adult on the left, this photo reveals that the chick had jumped onto the back of the parent and took shelter in moms or dads plumage while the family moved out of sight. As you may imagine I was tickled about having a first sighting in such a nice way! Yes, the light was very harsh but having this special moment out in the wild, and in addition a second lifer this year, matters more than a perfect photo to me.

NATURE CLICKS #609 - YELLOW-HEADED BLACKBIRD

Yellow-headed Blackbird, Star Lake, Ottertail County, Minnesota

The last kayak trip of our little Minnesota adventure had some wonderful surprising moments. We wanted to explore a new body of water outside of the state park and paddled Star Lake in Ottertail County, one of the larger lakes around. But size doesn’t matter, the water was crystal clear as at any smaller lake we paddled before. First it was not really exciting because homes and cabins along the lake shore didn’t leave much space for natural habitats. It wasn’t until we went deep into a big field of reeds and cattails on the other side of the bay when the fun of bird watching started. The call of a male Yellow-headed Blackbird is slightly different than the omnipresent Red-winged Blackbird (they were of course present as well) and before we even reached the reeds, we knew they were in there somewhere.

Today’s photo is the result of patience and quite a few paddle maneuvers for a view without too much obstruction by the reeds. It has been a long time that I had this beautiful bird in front of the lens and I was thrilled to see and finally photograph them again.

SEEING THEM IS THE CHALLENGE

Yellow Warbler, Southern Lida Lake, Maplewood State Park, Minnesota

Unfortunately I do not always have enough battery charge on my computer to work on photos and write something for the blog. However, birds, trees, and flowers. are abundant here in Maplewood State Park, Minnesota. We make a kayak trip every day and enjoy this very quiet and beautiful nature place.

We have never heard so many different warblers around our campsite and along the shore of the lakes before. Seeing them is a different story, they know how to hide under the lush canopy of the trees.

This Yellow Warbler was visible for a few seconds and I tried to catch it with the camera from the kayak.

A SYMBOL OF THE NORTHWOODS

Common Loon, Beers Lake, Maplewood State Park, Minnesota

Two fantastic paddle trips are already behind us . We had great opportunities to watch and listen to birds, often in our campsite, were we use the Merlin App to identify them even if we can’t see the birds high up in the canopy of the trees. On the water I’m always thrilled to see the Common Loons, the Minnesota state bird, and we saw them and heard their distinctive calls on almost every lake so far. I have been in Norway, Sweden, and Finland many times and it is easy to understand why so many Scandinavians have settled in Minnesota after they came over to America years ago. The glacier shaped landscapes with thousands of lakes and dense forests are very similar in many parts of the country and the settlers must have felt right at home.

I have been brave despite Beers Lake was a little choppy yesterday and took the camera and long lens with me in the kayak. Well, I forgot to take the teleconverter off but that turned out not to be a bad thing with and 840 mm focal length allowed to fill the frame quite often with the beautiful Common Loons.

TALKING ABOUT THE ”CUTENESS FACTOR”

Double-crested Cormorant, Mississippi Valley, Green Island Wetlands, Eastern Iowa

Let me start with some thoughts before I come to today’s image. In the Dubuque Camera Club we participate in monthly competitions with other camera clubs in different categories with our photos each month. We also have the duty of judging a competition quite often. In the month of May it was for the ”Nature” category, means wildlife, flowers, or anything else that falls under the umbrella of nature. This is all good and helps many beginners and advanced camera owners to become better photographers.

Over the years, since I’m a member of the club, I made an observation that still keeps me wondering. Nobody can win a competition if the subject doesn’t have a certain ”cuteness factor”. For example, if you post a real blurry photo of a cat (I mean house cats, lions, tigers, you name it…), not even very well composed, and as boring as a piece of wood in the bright sun, sometimes it still may be judged higher than a tack sharp, well composed, and properly exposed picture of a beautiful snake. It doesn’t matter anymore if the story a photo can tell is good, when the ”cuteness factor” kicks against it. I understand, it’s all subjective and the three judges never have an easy job to find a fair winner. It just still amazes me what role the ”cuteness factor” can play how we can feel about a photo.

So, here we have a Double-crested Cormorant and I know this bird is considered by some people as ugly. I guess the ”cuteness factor” may be ”a bit” less than i.e. for the Great Egrets I posted yesterday. However, this very adaptable bird is an elegant diver, swimmer, and flyer an I personally think they just look great. Due to their black plumage, making a well exposed photo is often a challenge.

The Double-crested Cormorants have a home in the Green Island Wetlands during the season with open water and they are abundant. I see them quite often, but making a photo without cropping the picture to death seems to be not so easy. It was the first time this very skittish bird was within the range of the lens and in decent light. I admit, the ”cuteness factor” doesn’t play a role in my wildlife photography. All animals need our utmost attention for their protection in their still shrinking habitats.

DIFFERENT PREY

Great Egret, Upper Mississippi Valley, Green Island Wetlands, Iowa

The Great Egrets in the Green Island Wetlands have no problems to find and catch food at this time of the year. The metamorphosis from a tadpole to a frog was not yet completed for the prey the egret had in its bill, but I can see the legs of the frog already in a different photo of this shooting sequence.

Tadpoles or frogs were not the only items the Great Egrets had on their menu this afternoon. Another one caught a young Northern Pike and gobbled it down into its throat within a few seconds. The interesting thing to observe was the behavior of the egret after it had the fish in its beak. The Great Egret was smart enough to know that it can loose the pike during the attempt to swallow it and the bird just jumped onto the shore where it could pick up the fish again if the prey was accidentally dropped.

SCOUTED A NEW LOCATION

Dickcissel, Driftless Area National Wildlife Refuge, Pine Creek Unit

I got this tip from Mike, a gentleman I met last week at Mud Lake below the two nesting towers that are provided for Purple Martins. It turned out that he monitors not just these two towers, but some more at other locations in the area. Pretty soon we had a very good conversation about birds and nature habitats. Mike told me about the Pine Creek Unit of the Driftless Area National Wildlife Refuge and mentioned it as a good birding location. This area is located near Colesburg, Iowa, actually not very far from here, but I didn’t know about it. Thank you again Mike!

Orchard Oriole, male in its 1st summer

Well, yesterday I checked part of it out and although I spent only an hour and a half in this habitat with grassland, brush thicket, and forest, I had quite a few bird encounters and came back even with some photos. Be forewarned, there are not really any trails or roads in this area and I would recommend hiking boots and a good look at the map by the kiosk in the small parking lot at the end of the road.

American Tree Sparrow, this was a surprise for me since I have never seen them here except during winter time. Their breeding grounds are in Alaska and northern Canada.

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.

MANY NESTING ACTIVITIES

Eastern Bluebird. The male observes the neighborhood in a nearby tree before he brings food to the nestlings.

There is a lot going on in the woods and the nest boxes around here. Hard to follow it all with equal attention.

The Eastern Bluebirds in the nest box have hatched a few days ago. I had a brief look into the box but wasn’t able to see how many nestlings came out of the five eggs because the nest is very deep. Time will tell. Both parents are feeding vigorously and bring caterpillars, spiders, little worms, and moths to their offspring every few minutes. I saw the male still catching insects tonight at 8:45PM . It’s a hungry bunch!

Female American Robin preparing a new nest

Yesterday a female American Robin was building a new nest in a tree just across from my office window. It might be even on top of a first nest that most likely was built at the end of April already. With other words, they work on the second brood already. The female collected very quickly dried grass and other plant material and glued it together with wet dirt from underneath a bird bath. After dropping the grass in the nest the robin rigged it with her feet and it looked like she was trampling it in place. The male watched the surrounding area and chased everyone away that came close to the nest. I saw him a couple times going after the bluebird.

Male House Wren inspecting a nest box.

The tiny male House Wren still sings his heart out to attract a female to one of the nest boxes we provide for them since many years. Once in a while he inspects one of the nesting chambers and the photo was made when he came out of the hole. As I said before, hard to follow all nesting activities at this time of the year…

NATURE CLICKS #606 - BOBOLINKS, READY FOR THE NESTING SEASON

Male Bobolink, Technology Park, Dubuque, Iowa

Bobolinks have one of the longest migration routes. They spend the winter in Bolivia, Paraguay, western Brazil, or northern Argentina. They breed in grassland habitats and it is important that the grass is not mowed during the breeding time. This happened unfortunately here in the Dubuque, Iowa area in one of the habitats in 2023, due to human ignorance. The Bobolink is one of the few songbirds that undergo two complete molts each year. After breeding the male changes to a more drab and camouflaged plumage.

I found at least 4 male Bobolinks today and saw briefly even a female in the grass of the Dubuque Technology Park. The Dubuque Audubon Society has worked with the city so that mowing in the undeveloped lots takes place only outside of the nesting season. Signs around these areas inform the public about this natural treasure. Other bird species can be present as well and toady I saw American Robins, an Eastern Meadowlark, Barn Swallows, Red-winged Blackbirds, and an Eastern Kingbird.

I made a number of shots while standing or kneeling at the edge of the grassland lots but the distance to the birds was a little bit too far for a pleasing photo. Later I parked the car with the driver side against the curb and shot both photos from my ”mobile blind”.

WARBLERS, GREAT SUBJECT FOR TESTING

American Redstart, Bankston County Park

Just back from a business trip I had the desire to go out and look for some wildlife yesterday evening . The steep and wooded river valley in Bankston County Park has been a good spot many times before and in the month of May there is often a good chance to get some warblers in front of the lens. Both species I found will probably breed in this area and there was a lot of calling going on.

It was the first time I didn’t bring the tripod and relied completely on my handholding capabilities and the amazing focus system of a new Nikon Z 6 III. It was very windy, even in the valley, and these little birds never seem to hold still, but I had a good number of sharp shots I could choose from for this blog post. I have used the new Z6 III since two weeks now and all I can say is, I’m very impressed with its focus system after extensive testing with the long lens and the teleconverter attached.

ON GUARD

Eastern Bluebird, female

Eastern Bluebird, male

This was nine days ago and I knew there were at least five eggs in the bluebird nest box. It was a warm evening and even the female spent time away from the nest, certainly returning for the night later. Both parents were frequently perched in a tree that still had some gorgeous sunlight not far from the nest and they had always an eye on it. The bluebirds obviously avoided to draw attention to the location of the nest. This all made for a good photo opportunity with the long lens and the teleconverter attached, so the parents were not concerned about my presence in the backyard.

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…
