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.

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.

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.

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…

NATURE CLICKS #538 - SHARP-SHINNED HAWK

Sharp-shinned Hawk, Little Maquoketa River Valley, Iowa

Life isn’t always easy for the birds that come to our feeders and heated water bowls near the house. Yes, they have food and water but it also attracts predators, like this Sharp-shinned Hawk. When most of the birds suddenly hide in panic in nearby bushes and the woodpeckers freeze motionless on a tree trunk, it is a sure sign that a hawk is somewhere in the trees or is gliding through the woods.

Today the sound of a little bird hitting a window made me aware that something was going on outside. The hawk was perched just above some of the bird feeders. I believe it is a female “Sharpie”. The bird was fifteen minutes in that tree and gave me plenty of time to change the lens on my camera, open the window, and start shooting before she took off. Who knows, this might be my last “Nature clicks” blog post for 2022, but nature is always full of surprises and we have still seven days left this year…

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.

3 BIRDS, 3 THOUGHTS

Northern Cardinal

I have three photos and three little stories or thoughts for you today. It all accumulated during this week as much as the snow did here on the bluffs above the Little Maquoketa River Valley.

All three pictures were made in the ‘backyard studio’, which means around the house. I did a “mini class” on bird photography with speed light during our “flash workshop” at the last meeting of the Dubuque Camera Club. However, no flash was used to boost colors this time because the giant reflector, called ‘snow’, took over this function. I was really happy to see some great results on social media of other photographers who applied some of the ideas I taught to their own photography (John Leicht, you are on the right track!).

This Northern Cardinal is part of the gang, joining us every morning and evening. Not a great gesture, but look at the shaft of light that hits this fellow during sunset time…

Yellow-shafted Northern Flicker (hybrid?)

I have photographed this guy before. Usually male Yellow-shafted Northern Flickers have a  deep black mustache but this must be a hybrid between a red-shafted (hence the red mustache) and the yellow shafted Northern Flicker (hence the yellow undertail). Not really uncommon, but the line where both races overlap is usually much further west. Any thoughts from other birders about this topic are more than welcome.

American Robin

When I moved to this country almost 15 years ago and started to learn about the birds of North America I quite often heard, the American Robin migrates and we don’t see them here in this part of the Midwest during the winter. The reappearance in March, or even April, was celebrated as a sure sign of spring by many people. I thought this was true for a long time, but during the last 4-5 years I have always seen American Robins during the winter. This season, now with temperatures way below 0ºF (-16ºC), the robins still come to the water sources we provide. A bird will show up only at feeders if either food, water, and/or exceptional safety are nearby. In case of the robins, they don’t eat really any of the food we provide. Ones in a great while I see an American Robin feeding on a suet feeder that we have out there for the woodpeckers. What draws them in is the abundance of juniper berries from the Red Cedars that grow on the limestone bluffs above the valley here. I guess this kind of food must make them very thirsty…. I refilled both of our bird baths with more than a gallon of water (2x 3.87 liters) today. Sure, part of it is the low humidity, letting the water evaporate more quickly, but it is amazing how much liquid these birds can consume within a short period of time.

NATURE CLICKS #418 - EASTERN BLUEBIRD

Sure, this is only a picture taken at a bird bath but this is a favorite place of the four Eastern Bluebirds that visit our backyard frequently. They come in to drink and quite often sit at the edge of the pool and warm up a little. I have photographed them many times but this is the first time that I was able to make a photo of a female and male side by side and both birds in focus.

GUESS WHO IS STILL HERE!

Yellow-rumped Warbler, near Durango, Iowa ----------

In December 2017 I reported that we had a Yellow-rumped Warbler still coming to the bird bath and feeders despite temperatures way below freezing (http://www.exnerimages.net/blog/2017/12/31/happy-new-year). Guess what, the female warbler is still here and I saw her today eating from a suet feeder and hanging around for a little bit.

NATURE CLICKS #356 - EASTERN BLUEBIRD

Male Eastern Bluebird

One of the prettiest visitors in our yard is the Eastern Bluebird. We have at least four that fly in every day to drink or just sit at the bird bath to warm up a little. I shot this through the glass of a window. They are very skittish and fly away as soon they sense some movement. The glass has a little softening effect on the image. This benefits the background but makes it more challenging to obtain sharpness on the bird. The bluebirds are often in company with some American Robins that stay here despite the cold temperatures we had last weekend. What keeps both species here during the winter is probably the supply of juniper berries from Eastern Red Cedars that grow here on the bluffs of the Little Maquoketa River Valley. Bluebirds feed on insects, earthworms, snails, and other invertebrates during the summer but are highly dependent upon berries during the winter.

NATURE CLICKS #355 - NORTHERN FLICKER (YELLOW-SHAFTED)

Male Yellow-shafted Northern Flicker -----------

We had quite a bit of snow during the last two days and the temperatures dropped way down (-22˚ C / -7˚ F). 17 different species of birds can be found in these tough times at our bird feeders and water supply and I’m not counting those who show up only occasionally. The flickers have found out about our place again and this season we see at least three males and one female.

The Northern Flicker has two subspecies, the red-shafted and the yellow-shafted. Here in Iowa and the eastern US we have the yellow-shafted form. The image below is not a real good photo but I wanted to show it anyway. While I focussed on the female sitting at a bird bath it suddenly turned its head for an incoming male. Although the male bird is not in focus, you can see why this subspecies is called the yellow-shafted.

NOW HERE AGAIN, CEDAR WAXWINGS

A few days ago I posted a photo of a Cedar Waxwing in the rain, shot up north at Lake Superior in Ontario, Canada. Today we had many of them around here in our woods. This is not the first time that we see them in the fall, mostly in company with large numbers of American Robins.

It is probably the berries of the Red Cedars (Juniperus virginiana) that may attract them to hang around here at this time of the year. During the summer we have seen them mostly along the shore of lakes or rivers we paddled with our kayaks. Beside the food from the trees the waxwings take advantage of the water we provide at four different places. With so many other birds around at the moment it is less dangerous to stick the head in the bowl and drink. If a predator shows up there will be plenty of warnings for them.

READY FOR A DRINK (OR A BATH)

American Robin -------     

The days are getting shorter quickly and there isn’t much daylight left after I’m done with my work. On the positive side are the more frequent visits of many birds in our yard. Today we had four different woodpecker species around here and I saw a Brown Creeper going up the trunk of a tree. A first this season.

In the fall the American Robins stick together in small flocks and take advantage of our four bird bath bowls. The photo opportunity comes right before they go to the water source. Most of the time they perch briefly on a branch or sticks I have mounted near the bath. The robins look carefully around before they jump or fly to the water bowl to make sure no predator is nearby. 

I shot in “sniper mode”, with the Better Beamer flash extender for color enhancement. The sun was already behind the trees but left still some ambient light for this photo. A few minutes later it would have been too dark and using flash as my main source of light is not an option.
