OH, THAT BIG REFLECTOR!

Male Eastern Bluebird

Some of the followers in my blog may say, oh boy, he is posting Eastern Bluebirds again, we saw that a few times during this winter season already… And you are right, but as much I try to report about the variety of wildlife we have at a certain time here in the woods of eastern Iowa, the photography related questions make me change my focus about what I like to post here in the blog sometimes. So why the bluebirds again? First, the fact that a flock of about ten birds has been around all winter long has been a first time experience during the last twenty-one winters we live here on top of the bluffs of the Little Maquoketa Valley. But with all the pictures I took recently there is one big thing missing, the great reflector from underneath that a fresh layer of snow can provide. Gosh, I love this kind of light that make very critter pop because the reflections from the snow below give it a quality that no other season during the year can deliver.

Both photos were shot through the glass of the balcony door. As I mentioned sometime before, the distance to the next bird bath is too short for using the Nikon Z600/ f6.3. Well, it’s a good thing that the Sigma 150-600 is still in my possession and with its about 9 feet (2.8m) minimum focus distance it works well for this location…

With all the technical talk that hopefully helps other photography friends with their own endeavors , its all about the beauty of our wildlife we are able to enjoy.

DEFYING THE POLAR VORTEX

A Polar vortex-driven Arctic blast hit the country during the last few days. Not so much new here in the Midwest but when the beaches in Florida or Alabama are covered with snow it’s worth to mention it. The cold weather here led to an increase in numbers of birds that visit our feeders and bird baths. I counted the highest number of Eastern Bluebirds we ever had seen here at the same time (10) and assuming there were at least a couple more up in the trees. Of course I’m not the biggest fan of having the bird bath in the frame but it was the only way to tell the story about the large congregation we were able to enjoy. Other birds use the safety of being in a flock as well and among the bluebirds we find American Goldfinches, House Finches, Sparrows, and the occasional Cedar Waxwing.

At temperatures as low as -26ºC (-15ºF) I fill all five suet feeders for the woodpeckers and nuthatches and still, some birds have to wait in line for their turn to feed. The larger species, like the Red-bellied, or Hairy Woodpeckers dominate while they are present and the much smaller Downy Woodpeckers wait patiently until their larger cousins are done. A popular ”waiting spot” is the small oak between two of our bird feeders. A few snow flurries danced down to the ground today, adding to the story of cold winter weather while this male Downy waited for his turn to feed.

DID SOMEONE SAY ”NASTY WEATHER”?

Eastern Bluebirds

I’m not a big fan of the term ”nasty weather”. It was probably invented by couch potatoes that never set a step outside their doors when the sun is not shining… Well, today I don’t mind to use the term (sorry my fellow couch potatoes!), because the day started with sleet, followed by rain, and a snowy mix, and within a half an hour it led to an ice cover wherever the eye went.

It was a good reason to stay home all day and try to capture what’s around bird feeders or who visits the heated bird baths in the front or backyard.

I’m sometimes puzzled by what the so called ”influencers” post on their websites, blogs, or podcasts on the internet. Just recently I came across an article about having a clear glass filter in front of the lens leads to a significant decrease in picture quality. Not supported by any real facts. I’m not the only one (some real famous photographers do it as well) that attach a clear glass filter to their expensive lenses in order to protect the front element of the lens against any unpredictable physical impact. Most of us still have to work hard for our equipment…

Well, today an additional sheet of glass was between the sensor of the camera and the subject of interest. I had to shoot through the glass of the balcony door here at home.

The Eastern Bluebird in the back was in focus when the second one in the front spoiled the party and landed on the rim of the bird bath. First I wasn’t happy but finally accepted that it adds to the story. A little more subtle is the streak of rain near the upper right corner of the photo. Who will doubt that this was shot in ”nasty weather”?

Here is a little trick for dealing with the slight blur of a glass window. Use the ”Dehaze” slider in Adobe Lightroom or ACR, just with a slight increase by +2 - 4 steps. It works wonder! Other, non-Adobe software has probably a similar feature under a different name.

While everything around, the boards of the balcony, trees, or of course our drive way were covered with a layer of ice, the only place that wasn’t you can see in this picture. The heated bird bath prevents the stone at it’s edge from freezing over in such a weather. The bluebirds love this spot, and so does the photographer…

HAVE TO LOVE THOSE BLUEBIRDS

Male Eastern Bluebird

My photography friend Kevin had invited me every year to his backyard during the breeding season of Eastern Bluebirds and many good shots are in my photo library due to his generous sharing of the location. I would like to do the same, inviting him for a shooting session during the winter season. Kevin knows when the bluebirds hatch in the nest boxes that he puts out at the edge near the woods of his property and the chances are always high to come home with a decent image of a parent bird with food in their bills. Well, I would like to return his favor but the visits of Eastern Bluebirds at any of our three bird baths are not predictable. Yesterday I had eight birds coming to the water bowl on our balcony, but today, with even more time on hand to watch, none of them showed up.

We didn’t see any bluebirds during last winter season but the bird droppings beside the bird bath tell me this time, we have a good crop of juniper berries in the eastern cedar trees that grow here on top of the bluffs of the Little Maquoketa Valley. The short appearance of two Cedar Waxwings yesterday, another bird that feeds on juniper berries during the winter, seems to confirm my observations. Well, enough of bird biology. I hope you enjoy my photo of this male Eastern Bluebird today and have a wonderful weekend.

NATURE CLICKS #589 - EASTERN BLUEBIRDS

Eastern Bluebird, male

Much colder temperatures and a bit of sun today have increased the activities around the feeders and bird baths in the front yard. It was only a couple days ago that finally the water bowls had to be connected to a power supply for the heaters. Later than any other year before.

We see a lot of goldfinches and sparrows beside the regular birds, like titmice, chickadees, nuthatches, or all the woodpeckers at the moment, but the most exciting visitors were six Eastern Bluebirds today. I never see them eating any seeds but they seem to love the warm water of the water bowls. We had bluebirds during other winters before but never so many at the same time.

Despite the cold air it was fun to shoot with some nice light after all the dark and gray skies we had lately. I didn’t bother to set up the tripod and just enjoyed handholding the Nikon Z600/f6.3. The light weight of this new lens allows for quick changes of my position and for trying to keep up with the birds.

CARING PARENTS

We have quite a few stories going on here with birds building a nest or having it already and feed their young ones somewhere around the house. Not for the first time a pair of American Robins built it right on our balcony and they are very busy since a few days, stuffing food into four hungry bills that stick out of the nest.

In the backyard is a bluebird nest box but the last couple years the more aggressive House Wrens took it over and the bluebirds had no chance. Finally this season a pair of Eastern Bluebirds were able to incubate and now the parents started feeding their offspring. How many bird babies are in the nest? We don’t know yet and we do our best not to disturb the birds.

@ 600 mm, 1/400 s, f/7.1, ISO 1000, photo slightly cropped.

I placed myself with the tripod next to some bushes beside our house and wanted to blend in as much as possible. The bluebirds did not hesitate to fly with food to the nest, a sure sign they accepted my presence and didn’t see me as a danger. They land first in a nearby tree and observe the environment of the nest box before they actually enter the entrance hole. The first photo was made at such a perch and I used the 1.4 teleconverter plus a little bit of cropping in post process to keep a safe distance. No picture justifies a threat to the life and well being of an animal.

NATURE CLICKS #572 - EASTERN BLUEBIRDS

Male Eastern Bluebird. Their vibrant blue feathers during breeding season are easy to spot between the trees, even under low light conditions.

Shortly after our return from Oregon I saw a pair of Eastern Bluebirds inspecting a nest box I have built for this particular species a couple years ago. I saw both, the female and the male last weekend again and my hopes grow that they may take possession of the place and built a nest. The biggest competitors are the House Wrens and the first one has already arrived. Last year a male wren stuffed a lot of loose little twigs and branches into the hole and as I later found out, all on top of a bluebird nest. The wrens are much more aggressive and the bluebirds had no chance. We have several bird boxes for the House Wrens but they have their own mind and choose whatever place they like the best. Since we had a breeding pair of Eastern Bluebirds in 2020 in another nest box I still hope it will happen again.

The colors of the female are much more subdued. After a male has attracted a female to his nest site, the female actually builds the nest. Both parents feed the brood.

BUSY BLUEBIRDS

Female Eastern Bluebird

There was some hope a few weeks ago that we may have a pair of Eastern Bluebirds building a nest in a special nest box I provided for them. They tried, but we have a number of House Wrens here in the woods and the males are pretty aggressive and kick any other bird out of a cavity if it is within their claimed territory. So, no bluebird nest again this year in our backyard. I never mind seeing the wrens raising their offspring but it would be nice having young bluebirds as well. Luckily my photography friend Kevin has a pair of bluebirds again this year in one of the nest boxes he installed near his house and he invited me for a shooting session while the parents fed the offspring in the nest last weekend.

There were some interesting observations to be made. During the whole time, more than an hour, the female didn’t feed the young birds at all. She had food available and in its bill and seemed to act as a backup. The male flew in and kept feeding the brood from time to time. I saw the female swallowing a caterpillar and coming back quickly with another one, but she never entered the nest box. I’m not sure if she gave some of her catch to the male, but he was the only bird feeding their offspring.

Kevin and I had plenty of opportunities making a photo of the female bird while she posed nicely on a branch near the nest box. The males are a lot more colorful but the busy bird flew most of the time directly to the wooden box, checked the surrounding area for any possible danger, and quickly went into the entrance hole. Good times as always, and my thanks go out to Kevin for giving me the opportunity for this photo shoot!

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.

TWO BEAUTIES

Female Eastern Bluebird

The day started with some snow removal. Fresh snow means the birds will come to our feeders and bird baths in larger numbers. It was nice to see a couple Eastern Bluebirds among them this morning. They are not here for the sunflower seeds. The bluebirds depend on berries during winter and the juniper berries of the Eastern Cedar trees, that cover the rocky bluffs here at the Little Maquoketa Valley, are probably their primary food source. A reason why we see the Eastern Bluebirds only at the heated bird baths that we provide. Beside drinking they sit there sometimes for several minutes and obviously warm up a little bit when it is cold.

Male Eastern Bluebird

To open the glass door to the balcony and stick the lens out into the open for making a click is not always an option. Some birds may not come to the feeders, like the cardinals, but most importantly the warm air that mixes with the cold air outside will create a heat shimmer and make getting a sharp focus almost impossible.

I take the lens shade off the SIGMA 150-600 and keep the front element of the lens as close as possible to the glass of the door. This is of course no optical glass and some blur may occur. The Dehaze-slider in Adobe Lightroom becomes very helpful for solving this problem and removing the extra blur on the bird. Lightroom’s new masking functions allow to keep the blur on the background and make the bird even stand out a bit more. All what I can say is, shooting through the glass of a window or door has never been so easy…

DISCUSSING BLUEBIRDS

Tonight the Dubuque Audubon Society had a program about bluebirds. Jessica Carryer from the Joe Davis Conservation Foundation over in Illinois discussed everything from habitat, how to monitor a bluebird nest box, to all other aspects of conservation of this beautiful bird species with the audience. It was very interesting and gave me and other members of the Audubon Society new ideas for our own conservation efforts.

I thought this was a good reason to present you another photo from a shooting in July with my photography friend Kevin, who is also very active building and monitoring bluebird nest boxes.

This male Eastern Bluebird tried to lure the nestlings out of the box with a good size insect in its bill, but he little guys were not ready to leave that day. The location of Kevin’s bluebird box was perfect. The birds liked it obviously and it was very “photography friendly”, which allowed us to shoot with natural light from a safe distance, and without a bright sky or distracting background.

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.

HOLIDAYS WITH BIRDS

I trust you all enjoyed a wonderful holiday weekend and the photographers among you had a chance to aim their lenses at something interesting or learn and play with a new piece of equipment that you found under the Christmas tree.

As mentioned in the last blog post, it was our first Christmas without snow here but the mild weather was perfect for a hike yesterday and for some shooting with the long lens in the front yard today. Seventeen bird species used the stand that holds the perches, bird feeders, and a bird bath this morning and I used their presence to make myself more familiar with the new Nikon Z6II mirrorless camera. One goal was to customize some of the camera buttons to my preference, so I can operate and change settings at the camera on tripod with the right hand only and without taking my eye from the viewfinder. The left hand can remain on top of the lens barrel, helping minimize vibrations during the shooting process.

The American Goldfinch is in its winter plumage but still very pretty. This picture is a composite, actually showing the same bird. I had this idea when I saw both photos side by side on the screen.

The American Robins stay here for the juniper berries on the red cedars that grow on the rocky bluffs of our valley. They use the bird baths frequently and the best chance for a click is right before they jump down to the water from a higher perch.

The Eastern Bluebirds is another consumer of the juniper berries. Today we had three males and one female here.

The third bird that prefers berries during the winter time is the Cedar Waxwing. They sometimes “wait in line” when other, bigger birds occupy the water source.

Today I saw the first Purple Finch during this winter. They spend the summer up in northern Minnesota and Canada and we usually see them only during the cold season. The appearance of this female is a clear message that some real winter weather may lie ahead of us.

FIRST FIELD DAY WITH NIKON Z6II

The Eastern Bluebirds will hopefully stay here all winter long.

Today I had my first real field day with the new mirrorless Nikon Z6II camera. It started in our front yard this morning with three Eastern Bluebirds taking advantage of the water in our bird baths. But the real challenge was a trip to the Green Island Preserve, the wetlands along the Mississippi River south from here. It isn’t the season when wildlife is present in abundance but a few raptors, a bunch of American Coots, and a few sparrows gave me some good opportunities to practice with the camera and to develop some muscle memory for the shooting workflow that comes with an Electronic Viewfinder. I do not like shooting with my glasses but the EVF allows me to shoot without them. The new challenge is to keep my eye at the viewfinder after a click and evaluate the results or make changes in the settings menu just right in the viewfinder. As soon I move my head away from the eye piece and look for the brilliant screen in the back of the camera, well, I need my glasses again. It may take some time to memorize not to look at the screen, at least during wildlife photography.

A LITTLE DRAMA

Black Rat Snake

Let me start this way, this Black Rat Snake was not hungry anymore…

Yesterday evening Joan called me out of the house, telling me that there was a young bird in the grass. Suddenly we saw at least one more nearby and a pair of adult Eastern Bluebirds highly excited calling them into the woods. This was near at one of our nest boxes but we didn’t know that they used the box. Actually we didn’t see a bluebird near the house since last year, not even during the winter time. That was the first surprise. While I quickly snapped a picture of one of the fledglings resting on a pile of branches in the woods, Joan discovered the snake with one of the young bluebirds already half swallowed. This explained the upset of the parents a little better. It was a sad moment but we do not interfere with the course of nature. This is so unbelievable, because the last time I had one of these powerful large constructors in front of the lens in our woods was 2013!

Eastern Bluebird fledgling

We only can guess what really happened. The Black Rat Snake probably approached the nest box and the parents panicked and called the fledglings out. Maybe they were not ready yet. However, the snake had its meal. Today I heard and saw the bluebirds again briefly in the timber. It wasn’t clear how many of the young ones made it, but it sounded like the parents were not alone…
