Too much time in front of the computer lately, so a quick trip to Crex Meadows Wildlife Area in Wisconsin was in order. 

My main target was the OLYMPIA MARBLE, a small white butterfly that doesn’t look like much while flitting about a grassland, but when it lands it reveals the stunning underwings that are marbled with a glittery green/gold.

Because of my research on Mike Reese’s wonderful wisconsinbutterflies.org site, I found several only two minutes after I arrived. Hmmmm, this will be easy, I thought. But I quickly found out that these butterflies are very particular about which flower they land on…and it takes them a loooong time to do so.

Their host plant is Rock Cress (Arabis sp.), a 6-12″ unassuming plant with a few groups of 4-petaled white tiny flower at their apex. And there were many in full bloom in this patch of grassland.

With camera in hand, and flash ready to fire, I would follow a flying Olympia Marble across the prairie waiting for it to land on a Rock Cress after which I’d drop to the ground, prone on the prickly prairie, to get an eye-level shot of a stunning butterfly. But 9 times out of 10 (19 times out of 20?) the little butterfly would already have moved on by the time I was in position. The few times it did begin to nectar, it only did so for a very few seconds, leaving while I was still trying to focus on the very tiny flowerhead. I was left to grunt and groan as I tried to get back onto my feet to pursue it yet again.

Not only this, but I failed to realize that while the mosquitoes had not yet emerged in northern Minnesota, they were out if full force at Crex, and they were joined by their friends the Black Flies. No bug dope in my van. Zero. Despite the 75 degree temps I had to don my wool Ullfrotte jacket. Not comfortable.

I still wonder why the Marbles pass up countless Rock Cress that look perfectly fine to me….What do they know that I don’t? Are some already stripped of nectar? If so, how do they know? Smell? Look? 

Finally I was able to get in position and click off a few frames on a couple occasions. It only took 2 hours but I finally had a satisfying image showing the glorious underwings.

On a whim, Sparky stops by Crex Meadows in western Wisconsin on his way home from a conference in St. Paul…and despite the initial BLAAH light and heavy overcast, he stays and the light suddenly turns magical…WHAAT!

Sandhill Cranes and Trumpeter Swans are the avian highlights.

Sparky tries shooting through the red fall foliage to create some unique and creative wildlife photos.

Okay, okay…I must admit that I chose this “click bait” title for the Youtube upload of this video. Bad Sparky!

But will it work? Will I get more views compared to the original title…”EVENING AT NECEDAH: Whooping Cranes, Trumpeter Swans and more”? Probably, but I will never really know for sure since you cannot upload duplicate content to Youtube.

Regardless of all that nonsense, this was a MAGICAL two evenings at southern Wisconsin’s Necedah National Wildlife Refuge. I filmed 90 percent of this from the observation tower at the south end of the refuge. It was a dead calm and quiet evening.

A Whooping Crane was feeding along the marshy shoreline in the company of two Sandhill Cranes. Peaceful for a while, but then the MUCH LARGER Whooping Crane got too close to the intimidated Sandhills. Not really a “battle” per say, but the Sandhills definitely freaked out as the Whooper got close.

HISTORY—The world population of Whooping Cranes was down to 15 birds by 1941. Intense conservation efforts slowly allowed the population to build. The original group winters near Aransas NWR in south Texas and breeds in Wood Buffalo National Park in Alberta, Canada (a permanent non-migratory group spends the year near Kissimmee, Florida).

But biologists felt that they had “too many eggs in one basket” and that a winter oil spill in the Gulf could wipe out the entire migratory population. They started searching for a new place to establish a migratory flock. Enter Necedah.

The Necedah flock was established in 2001 with a handful of cranes that were famously taught to migrate south to Florida by following a glider. The bold experiment worked and today there are 79 adults making the round trip migration from Florida to Wisconsin each year. By the way, Florida was chosen over Texas as another way to spread the risk of a natural disaster killing off ALL the Whoopers.

Whooping Cranes have NEVER been common in North America. Even before white Europeans arrived on the continent the population was estimated to be only 15,000 to 20,000 birds. And they only lay 1-3 eggs but usually two and often only one survives.

Black Flies have caused many nest failures and mortalities at Necedah. Nesting in late April and May is at the peak of Black Fly emergence so incubating females are so tormented by the tiny flies that they abandon the nest. So a new method called “forced re-nesting” has been implemented by biologists to counteract this. They remove the eggs from the first nest of the season, which forces the Whoopers to renest at a later date after the peak of Black Flies. Success rates and fledgings have increased using this method.

The world population is now up to 800 birds as of 2021.

I also got to see and film two other species that I rarely see in the North Woods…the most lovely Red-headed Woodpecker and the caterpillar-feasting Yellow-billed Cuckoo. A real treat!

[Shot with Panasonic GH5 and Canon 400mm f5.6 lens on tripod]

During the icy grip of the February 2021 Polar Vortex cold snap, Sparky travels to the mostly frozen Mississippi River of southeast Minnesota and southwest Wisconsin to photograph Bald Eagles fishing open spots close to shore. He also looks for Golden Eagles inland in Houston and Winona Counties in Minnesota.

Bitter windchills means frozen toes and fingers, but the Canon R5 does an amazing job of autofocus while shooting super slow motion (4K 120fps) video of the eagles.

A trip to Old Frontenac Cemetery nets Sparky’s first photos and videos of Tufted Titmouse in Minnesota.

The trip ends at Crex Meadows near Grantsburg Wisconsin where an unexpected Gray Fox and Red Fox make a dusk appearance.

Parasitic Jaegers migrate through Lake Superior in spring and fall. We often see them harassing gulls in mid to late September off of Duluth, Minnesota’s Park Point and Wisconsin’s Wisconsin Point. Long-tailed, Pomarine and Parasitic can all be seen here, but Parasitic Jaeger is the most common by far. They will somehow single out an individual Ring-billed Gull that it feels has a crop full of food. I suppose they can see the full crop. Then they perform the bird equivalent of a aerial “dog fight” and scare the gull into coughing up its last meal. The jaeger can often catch the regurgitant in mid air!

You will see a successful “hunt” in this video. By the way, “jaeger” is “hunter” in German.

These attacks were filmed in mid September off Superior, Wisconsin’s Wisconsin Point with the Panasonic GH5 at 180 fps.

June 25, 2020

I had a great day birding at Wisconsin’s Crex Meadows State Wildlife Area. It is near Grantsburg, Wisconsin and only an hour and 15 minute drive from our home in Carlton County, Minnesota.

Highlights include an Eastern Kingbird landing on the back of a Bald Eagle (!), singing Field Sparrow, Clay-colored Sparrow, Grasshopper Sparrow, Eastern Towhee, Black Tern, Trumpeter Swans with cygnets, foraging Sandhill Crane, and a sighting of the rare Blanding’s Turtle. (and loads of deer flies!)

Wildflowers including 4 species of milkweed! (including the rare Dwarf Milkweed (Asclepias ovalifolia), which was a lifer) and Butterfly Milkweed), also Spiderwort, Wood Lily, Prairie Larkspur and more.

Come along on this adventure!

October 22, 2018 (Monday)

**ALL OF THE BELOW PHOTOS ARE SINGLE FRAMES AS TAKEN…I DID NOT “ADD THE MOON IN PHOTOSHOP”

I ran into several photographer friends down in Wisconsin’s Crex Meadows Wildlife Area yesterday. I guess we were all thinking the same thing…Two days before the full moon is a perfect time to try and photograph Sandhill Cranes in front of a massive moon.

Lauren the naturalist gave me three locations to try for the dusk fly-in of the Sandhill Cranes. One was my “usual spot” along the Main Dike Road. I didn’t want to risk a new spot today so I stuck with my normal spot.

I ran into fellow photographer Mike Dec and we decided to shoot from the same spot. The wind was blowing strong out of the northwest, but the temp was in the low 50s. Cold fingers and shaking tripod!

Sandhills by the thousands roost in the wildlife reserve over night. The shallow-water marshes are basically inaccessible to most predators, and there is also safety in numbers. During the day the cranes feed in harvested corn fields outside the refuge and then fly in a bit before sunset. THOUSANDS roost here in the late autumn.

I was shooting slow-motion 180 fps video with the Panasonic GH5 on a tripod while trying to shoot stills with my Canon 7D and Canon 400mm f5.6 lens hand held. Every time a flock was approaching the moon at what seemed the proper trajectory to pass right in front, Mike and I alerted each other.

But focusing on the cranes was a challenge and I missed some shots because of my camera/lenses inability to lock on to a bird.

A memorable evening! Plan on being at Wisconsin’s Crex Meadows next late October.

The moon rose large behind a stand of oaks but there was little contrast between the sky and the moon. But over the next half hour the moon began to pop as the sky turned from blue to twilight purple. This flock of cranes were lit by the last orange rays of the setting sun.

[Canon 7D with Canon EF 400mm f5.6L USM lens; 1/1250 second at f5.6; ISO 640; -1.0 ev; hand-held; processed in Lightroom CC 2015]

Before the moon rose at 5:47pm, I took some flight shots with slow shutter speeds. I have so many sharp flight shots that I really don’t need more. Time to get a bit creative! So I slowed the shutter way down to 1/10 of a second at f20; ISO 100. The results are “very artistic” and impressionistic. Not everyone’s cup of tea, but I like it.

A couple “selective focus” shots. Basically impossible to get both the cranes and moon in sharp focus in the same shot (unless the cranes were about 2 miles away) so I tried some photos where I focused on the moon instead of the cranes.

These are single frames extracted from a HD slow motion video.

The above three photos of the roosting Sandhill Cranes were taken well AFTER SUNSET. Long exposures on a tripod. As usual, I was the last car at the spot. You never know what image might present itself after the “main show” is over.

[Canon 7D with Canon EF 400mm f5.6L USM lens; 1/400 second at f5.6; ISO400;-1.0 ev; hand-held; processed in Lightroom CC 2015]

The above two photos are probably my favorites from the entire shoot. The top is the uncrossed version, and the bottom is cropped to just 4 cranes. I like that they are very SHARP for being hand-held (way to go “steady Sparky”!). I also really like the even spread of cranes and the position of the legs and wings of the crane silhouetted by the moon. And of course, the purple sky color is a bonus.

[Canon 7D with Canon EF 400mm f5.6L USM lens; 1/400 second at f5.6; ISO400;-1.0 ev; hand-held; processed in Lightroom CC 2015]

As the moon continued to rise after sunset, the color was washed from the sky. The only option was to catch a flock as they passed right in front of the moon.

[Canon 7D with Canon EF 400mm f5.6L USM lens; 1/250 second at f7.1; ISO1600;-1.0 ev; hand-held; processed in Lightroom CC 2015]

On my way out of Crex Meadows I saw this sight; three Trumpeter Swans silhouetted by the nearly-full moon’s reflection on a marsh. I took a bunch of handheld shots at ISO 12,800(!!), but should have set up a tripod since most are unusable.

Whooping Cranes, Karner Blue Butterflies, Red-headed Woodpeckers, Northern Barrens Tiger Beetles…These are the reasons I made my first visit to Necedah National Wildlife Refuge near Nacedah, Wisconsin on July 20th. I was headed from my home in Wrenshall, Minnesota to pick up my kids at the home of my brother- and sister-in-law’s in Sun Prairie, Wisconsin.

I ended up spending 6 hours here! This is one of those refuges that welcomes visitors and really concentrates on education, unlike many of our National Wildlife Refuges.

I hiked the 1.75 mile Boghaunter Trail and Boardwalk. It is named for the very rare Ringed Boghaunter dragonfly that lives in this fen. They emerge in May and have a short flight period so I did not see one on this trip…But I will be back!

Karner Melissa Blue butterfly (Lycaeides melissa samuelis) Necedah National Wildlife Refuge Necedah WI

I was amazed and pleasantly surprised to find that the nickel-sized Karner Blue butterfly was abundant, and easily the most common butterfly species out and about. Its caterpillar food plant is the native Wild Lupine (Lupinus perennis) which was just done blooming, but that doesn’t phase the adults which nectar on many flower species including the abundant roadside flower Bird’s-foot Trefoil.

This butterfly is a federally Endangered subspecies of the Melissa Blue.

Though I did not find my lifer Northern Barrens Tiger Beetle, I did see many of the small Punctured Tiger Beetle (Cicindela punctulata) named for the colorful pits on its elytra (wing covers). The are ferocious predators of other insects which it stalks on open sandy soil.

I’d never heard of Rhexia virginica (Virginia Meadow-Beauty) until I read the first Necedah NWR brochure I picked up. It is at the far northeastern edge of its range in Central Wisconsin. It is most common along the East Coast and Southeast U.S. It prefers open, wet and acidic sites.

Also known by the fun name, “Handsome Harry.” It is in the Melastomataceae, a family of mostly tropical wildflowers. The pink petals are asymetrical in shape, and the stamens are bright yellow, thick and bent. A very cool “lifer” for me.

Blanding’s Turtle (Emydoidea blandingii) Necedah National Wildlife Refuge, Wisconsin

You don’t see Blanding’s Turtles every day so I was very excited to find this large (and presumably old) specimen along the boardwalk on Boghaunter Trail. He was shy but I flipped him over to examine the beautiful red-marked carapace, and his bright yellow throat. Don’t worry, I quickly tipped him back upright after I snapped a few photos.

“One of the most critically imperiled turtles to be found in North America is the Blanding’s Turtle (Emydoidea blandingii), named for William Blanding, a Philadelphia naturalist who first described it. They are found from Ontario, Canada; south to Iowa and back east as far as New York. There is a small population of about 300 found in Nova Scotia. The highest population densities are found in the Great Lakes region. They are listed as state endangered or a species of special concern in nearly every state they are found in. The biggest threat these turtles face is the loss of habitat due to agriculture and from major modifications to streams and rivers, such as dam building. Blanding’s turtles have very specific habitat requirements that include marshes, sloughs, ponds, lakes, streams, creeks, and vernal pools with shallow water, soft bottoms and large amounts of aquatic vegetation.” [Text from the Rattlesnake Education & Awareness Blog]

I was able to combine business and pleasure yesterday (July 1st)… Well, It was really all business and a complete pleasure! I had heard of a bog near Cable, Wisconsin that held many Calopogon tuberosus orchids (Swamp-Pink or Grass-Pink) and I was hoping to get video of their ingenious and devious pollination method (read more below).
This particular peatland is actually classified as a fen. What is the difference between a bog and a fen? Bogs are usually stagnant water with very acidic waters. Fens have some water movement and are more basic in pH and richer in nutrients.
Calopogon tuberosus (Swamp-Pink or Grass-Pink orchid) is a delightful mid summer orchid that grows in the floating mat of bogs and fens. Its flowers are “upside down” as the lip is actually on top. The insect-enticing yellow hairs are just a ruse…They fool insects into thinking that they are pollen-tipped or hold nectar, neither of which is true. If a heavy enough bee comes along, it gloms on to the yellow-tipped hairs and tries to extract some pollen. The flower has a built in hinge that collapses and drops the bee on to the sticky pollen packets below. The startled and frustrated bee flies off to try his luck at another Calopogon, and the scenario is repeated, though this time pollination is completed. Devious and Delightful orchid!

Note that on the middle right flower the hinge has already been collapsed by a visiting bee. Though I got video of several small syrphid flies visiting the orchid, none heavy enough to collapse the hinge paid a visit with my camera rolling. Oh well, a reason to go back!
Believe me, I was shin deep in water and sinking fast as I took this image. This is an example of a “flag” spruce… A growth form that is very common in the subarctic lands. The “flag” is the upper branches while the nonexistent middle branches were scoured by winter winds and failed to thrive. The sprawling mass of branches low down on the trunk survived because they were protected by deep blanket of winter snow.

Elfin Skimmer male (Nannothemis bella)
A wonderful surprise! Just days after Jim Lind and Dave Grosshuesch found many Elfin Skimmers at the Sax-Zim Bog BioBlitz III (a new species for Sax-Zim!) I got my lifer dragonfly! This is the smallest dragonfly in North America at a tad over 3/4 inch long…and the second smallest in the World (one in China is a bit smaller). The male is pruinose bluish and almost appears to have a clubbed abdomen when in flight.
Female Elfin Skimmers (Nannothemis bella) are very different than the males. They show a ringed black and yellow abdomen. Both the males and females perch often and only move a short distance when disturbed. These were found hunting around a bog pool mainly on the floating mat.
Another orchid was just coming into bloom… the Rose Pogonia (Pogonia ophioglossoides) a delicate beauty of floating bogs. Genus name Ophioglossoides is from Greek meaning “snake tongue,” and I guess you’d have to use your imagination on that one, but the lower lip may resemble a fuzzy tongue to some.
A very exciting find was not one, but two singing Okanagana Cicadas. The male of each species produces a unique sound with their tymbal organs on their abdomen which vibrates and resonates in a cavity inside their abdomen and thorax. The Okanagana’s sound is a fast and steady high-pitched buzz.
Crimson-ringed Whiteface (Leucorrhinia glacialis) is a bog-loving dragonfly of mid summer.
Lincoln’s Sparrow was the most obvious avian bog dweller today, singing its beautiful hollow-can, echoey song from stunted Tamaracks and Spruces. Other birds seen in the bog included Nashville Warbler, Eastern Bluebird, Red-tailed Hawk and Eastern Kingbird. The oak-maple covered hills surrounding the fen held Pileated Woodpeckers, Scarlet Tanagers, Ovenbirds, Red-bellied Woodpeckers, Eastern Wood-Pewees and other deciduous species that would have no use for a bog.
Rhynchospora alba or White Beakrush (or White-beaked Sedge) was very common surrounding the bog pools.
Is there a lovelier leaf in the world? Yes, the “pitcher” of the carnivorous Pitcher Plant (Sarracenia purpurea) is actually a modified leaf. Inside a deadly mixture of rain water and enzymes can drown and dissolve the unwary insect. The plant is able to absorb important nutrients such as Phosphorous from the tiny carcasses with special cells low inside the pitcher. Good thing these guys aren’t six feet across!
One more carnivorous plant was super-abundant at this fen, Horned Bladderwort (Utricularia cornuta). The related Common Bladderwort is a predator that has dozens of tiny bladders on its underwater leaves. The hair-triggers on the bladders are set off when a tiny aquatic insect blunders by and sucked in to the bladder in a rush of water. The bladder now becomes a tiny stomach and the insect is dissolved by the plant.

[Continued from previous post]…There have been no Snowies in the Sax-Zim Bog this year so Dave and I headed to the urban “wilds” of Superior, Wisconsin (Duluth’s neighbor in the “Twin Ports”). We found two Snowies but they were not equally photogenic. One had been banded and painted by researchers so it could be identified from long distances. We got a few “insurance shots” and continued our search.

Snowy Owls have been wintering in the industrial areas of Duluth, Minnesota and Superior, Wisconsin for many years. When I was in college at the University of Minnesota Duluth in the early/mid 1980s, we would go down to the Port Terminal in the harbor (where all the warehouses and shipping docks were) and we could easily find a half dozen. There were probably a couple dozen wintering between there and Superior’s docks.

At that time, the harbor was a brushy mess crisscrossed by railroad tracks and dotted with junk piles and open garbage cans. It was the perfect environment for rabbits, pigeons, pheasants and rats…all great Snowy Owl food.
[All owl-in-flight shots taken with Canon 7D and Canon 400mm f5.6 lens set at Shutter Priority 1/1250 second and auto ISO. ISO ranged from 640 to 800 and f-stop ranged from f5.6 to f8]

Less than a mile away, we found this stunning female/young male (You can’t really tell, but in general, the darker the bird the younger it is and more likely a female). Don’t get me wrong, I love the nearly pure white adult males, but the speckled patterning on this bird was very pleasing.

Of course she sat on every ugly perch she could find…telephone pole, chain-link fence, scoreboard (see below). So we waited until she pooped. Why?, you might ask. Raptors always seem to “jettison” excess waste which is weight they don’t need to carry with them when they fly. Then she did and I held down the finger on my Canon 7D with the Canon 400mm f5.6 set to AI focus so the lens would continue to focus on the flying bird.

I couldn’t resist a little fun when I saw this Snowy land on the middle school’s baseball scoreboard. After all, she is a “guest from the tundra,” just with us for the winter!
