Northwest Minnesota—Part 2: Norris Camp & Big Bog, June 12-13, 2016

Heading east from Thief Lake WMA I decided to check out Norris Camp, a remote Minnesota DNR station in the Beltrami Island State Forest that I’d heard had a nesting Black-backed Woodpecker. I was pretty sure that I was too late as most woodpeckers had fledged young already. But I was in luck! And I spent a couple hours with this pair of rarely seen boreal woodpeckers.

The folks at the camp pointed out that this was the same mated pair that nested on the grounds last summer. How did they know? Notice the band on the adult’s leg; they actually banded them last year and both the male and female returned to nest only 100 yards from last year’s nest. Woodpeckers NEVER use the same cavity twice but always excavate a new nest; it may be in the same tree but usually not. In this case, the tree they used last year had blown down since last summer. I don’t know much about site fidelity or mate fidelity in woodpeckers but this was a very interesting anecdote that I will for follow up on.
Also note the male’s yellow cap; the female shows only black on the head. He’s feeding a young male who is already sporting his jaunty yellow forehead feathers.

While waiting and watching at the Black-backed Woodpecker nest, I was treated to a lifer butterfly. Not 20 feet away I noticed an orange butterfly that was repeatedly landing on the same fallen log. I finally took a closer look and lo and behold, a Macoun’s Arctic! This species only flies every other year in the North Woods so I just happened to be in the right place at the right time. They are found in openings in sandy Jack Pine forests, and that is exactly the habitat I was in. Males use the same perch as they wait for females.

When perched with wings folded, the Macoun’s Arctic is well camouflaged, like just another piece of bark. This species has a fairly limited range in North America extending from the North Shore of Lake Superior west and north to Churchill, Manitoba, British Columbia and just extending north into the Northwest Territories.

One of my favorite orchids found in the bogs of north central Minnesota, the Ram’s-head Ladyslipper. This small group was past prime as you can tell by the collapsed dorsal sepal on top of the slipper pouch. This may mean that the flower had already been pollinated. It is a very small ladyslipper, maybe 6 inches tall. This group was growing in a Cedar bog.

Big Bog sign IMG_3441

My last stop was Big Bog State Recreation Area (SRA) near Waskish, Minnesota on Red Lake. This is the largest patterned peatland in the lower 48, and massive in size. It was once home to Minnesota’s last wild Caribou herd which disappeared in the 1930s and 40s. Their trails can still be seen from the air.
The boardwalks is one mile long and a very pleasant hike. MANY interpretive signs highlight the human and natural history of the Big Bog.

This was my lifer Bog Fritillary! Unfortunately I mistook it for a different, more common species, and I didn’t take the time to get a really good photo. Oh well, just a reason to go back!
I was going to camp overnight in the area, but I got a text message on my phone that a Calliope Hummingbird had shown up in Duluth…in breeding plumage! This is a bird of the mountain west that has only been recorded in Minnesota a couple times…and never in its stunning breeding plumage. This was reason enough to head for home.

Five Hours in a Fen

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 orchid IMG_2153 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!
Calopogon tuberosus Swamp Pink IMG_2095
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!
flag spruce IMG_2207Believe 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 IMG_2109
Elfin Skimmer Nannothemis bella IMG_2114Elfin 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.
Elfin Skimmer Nannothemis bella IMG_2087Elfin Skimmer Nannothemis bella IMG_2080Female 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.
Pogonia ophioglossoides Rose Pogonia IMG_2048Another 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.
Okanagana Cicada IMG_2134Okanagana Cicada IMG_1949A 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 IMG_2146Crimson-ringed Whiteface (Leucorrhinia glacialis) is a bog-loving dragonfly of mid summer.
Lincoln's Sparrow IMG_2000Lincoln’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 White Beaksedge rush IMG_2019Rhynchospora alba or White Beakrush (or White-beaked Sedge) was very common surrounding the bog pools.
Sarracenia purpurea Pitcher Plant leaf IMG_1900Is 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!
Utricularia cornuta Horned Bladderwort IMG_1952One 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.

Dream Come True: Witness to a Great Gray Owl nest

Great Gray Owl nestlings in nest Hedbom Rd Aitkin Co MN IMG_6410Two Great Gray Owlets await mommy or daddy from their lofty nest in a large Tamarack.

I had the great fortune of having a good friend who was willing to share the location of a Great Gray Owl nest he had found recently. Kim Risen is a professional bird guide based out of Tamarack, Minnesota, who leads birding trips across the globe, from South Africa to South America to Costa Rica to Mexico and even in his ‘backyard’ of northern Minnesota. Kim found this nest on a June trip with a client. He’d seen young in this general vicinity several times over several different years. He graciously shared the site with me.

I first visited the Black Spruce/Tamarack bog with Kim and his wife Cindy on June 18th and made several more visits, the last on June 28th. Two owlets were in the nest until at least June 24th, then must have “flew the coup” around June 27th or 28th when we found them on the ground.

VIDEO SHOWING BEHAVIOR & COMMENTARY ON FAVORITE PHOTOS (7 MINUTES)

You can see more of my wildlife videos HERE

Great Gray Owl nestling Hedbom Rd Aitkin Co MN IMG_7396Note mom in the bottom left corner of the image…She was never very far away. The young were generally silent…until they saw an adult when they gave a loud screech (can hear it late in the video). But the female often gave a rising “Whoop!” call. Robert Nero, one of the world’s foremost authorities on Great Gray Owls, says this call “is often given by the female on the nest as a means of communicating with the male.” Robert Taylor, author of The Great Gray Owl: On Silent Wings calls this is “food request call” and it is given more frequently during years of low vole supplies. It likely helps the male find the female too as he delivers the food to her so she can feed the owlets. May this also be the female’s form of communication with the owlets?…”You’re okay…I’m right here.”

Great Gray Owl nestling Hedbom Rd Aitkin Co MN IMG_7390On June 28th I went to photograph the owlets from my blind…But I saw no action in the nest. Just as I was contemplating this, I simultaneously heard my cell phone ring as well as a screech from ground level. I assumed the screech was one of the owlets who’d left the nest. It was Kim on the phone and he was in the bog and had seen the young on the ground. As he was talking I found one of the owlets ‘teed up’ on a stump… “Found one! Gotta go.” I set up my tripod and folding chair, then draped camo netting over myself and started shooting. The owlet stared at me for 20 minutes without taking its eyes off me, though its posture relaxed over this time. Then when he/she was comfortable that I was not a predator, the owlet started to look around, and even stretch.

Great Gray Owlet stretching_0002STREEEEETCH! FRAME EXTRACTED FROM VIDEO CLIP. The young Great Grays often stretched like this…Working their flight muscles I imagine. Fortunately he was facing me head on and gave me this unique perspective. [Note that when you extract a frame from a HD video clip you only get a 1920x1080pixel image to work with…and it’s shot at 1/60 second…and its basically a jpeg. Very limited use, but fine for the web].

Great Gray Owl nestling Hedbom Rd Aitkin Co MN IMG_7389Though the owlets can’t fly at this age, they sure can get around! They will walk across the bog then climb leaning trees and stumps by using their talons for grip and using their beak to grab branches like a parrot, pulling themselves up, wings held over their back for balance.

Great Gray Owl nestling Hedbom Rd Aitkin Co MN IMG_7390 - Version 2 (1)The ticket to not alarming wild critters is to move slowly, stay low, avoid eye contact, and talk to them in a low soft voice (don’t whisper!). And stay in plain sight so you are not mistaken for a sneaky predator. I got very close to this owlet…Close enough to use my 10-20mm lens with full flash. I love the low angle and wide perspective which really puts the owl in its habitat.

Great Gray Owl nestling Hedbom Rd Aitkin Co MN IMG_7410The sibling to the owlet on the stump, is this fuzzball. I found him/her on a comfy cozy patch of super-soft Sphagnum moss. I laid on my belly, crawled towards her (got soaking wet!) and inched to within a foot of her/him. He/she began bill clacking, an alarm signal, so I snapped a few photos (full flash) and backed off.

I wish this little family well and hope they find many fat voles!

Hunting with a Great Gray Owl: Shooting with Sparky video

Great Grey Owl, Sax-Zim Bog, Minnesota

What are the odds? I took a compass bearing to head straight through the center of a large Black Spruce bog last week, hoping (but not really believing) that I’d possibly, just maybe, hear a begging young Great Gray Owl.

Less than a hundred yards into the bog, I stopped dead in my tracks; There was a hunting Great Gray only about 50 feet from me and only 10 feet up in a spruce! She barely looked at me, and continued hunting. See how the adventure unfolded in the video below:

Join me as I enter the dark and haunting bogs of the far northern Minnesota wilds in search of the elusive and giant phantom of the north—the Great Gray Owl! (How’s that for drama!)

I especially like this Great Gray Owl photo because of several factors:
a. It was NOT shot along a road…like 99.9% of all Great Grey Owl images.
b. She is NOT looking at me…She (or he?) is busy hunting…too preoccupied to worry about a mere human.
c. I love the out of focus wispy Tamarack branches…Lends an air of wildness and hints at their bog habitat.

All photos taken with Canon 7D and Canon 400mm f5.6 (sometimes with 1.4x or 2x teleconverter), tripod, processed in Aperture.
All video shot with equipment listed above at 1/60 second and processed in iMovie.

Gray Morning Great Gray

Great Grey Owl

On Memorial day, I got up very early to make a quick trip to the Sax-Zim Bog. It was a gray, misty morning but calm. And the resident birds seemed energized after several days of heavy rain and thunderstorms.

And at 9am I got a wonderful surprise…A Great Gray Owl was hunting voles along McDavitt Road. This probably means that this owl has a nest full of begging beaks somewhere in the vast Black Spruce/Tamarack bog. I was able to get some video and photos as he/she hunted the wet ditch sides. Not very concerned with me, she eventually flew deeper into the bog. I was able to get this photo from the car window by bracing the 400mm lens on the door frame.

I tried to maneuver the car a bit to minimize background clutter and this is the best I could do. I don’t really mind the background branches as much as I thought I would…And I love the lichen-festooned branch the owl is sitting on. Ninety-plus percent of Great Gray photos you see were taken in winter, mainly because that is when they are more visible as they hunt open meadows and roadsides. Summer usually finds them hunting deeper in the bogs. This image has a warmer feel than those.

Also note that my camera was ready to go in the seat next to me when the Great Gray appeared; It was preset to Tv (shutter priority 1/400 second and auto ISO. This way I knew I could shoot handheld and still get a sharp image…And I can live with the noisier image at ISO 1000. If I’d had my camera on aperture priority f5.6, I may have ended up shooting at a slow shutter speed and getting an unsharp and unusable image.

Elsewhere in the Sax-Zim Bog I had some interesting birds. Though no “wolf whistles” of the Upland Sandpipers were heard, a very surprising Western Meadowlark was singing; Easterns are more common here. In the same field, a lone Sharp-tailed Grouse sat atop a wooden fence post. Nobody told him the party was over three weeks ago! Magpies foraged in hay fields along CR229. Bobolinks had also arrived.
I flushed a group of 6 American Woodcock from a clump of hazel…likely a family group as they nest early and stay together for a while.
In the Black Spruce bogs Connecticut Warblers were found at several locations including a couple males singing on opposite sides of one road. Blue-headed Vireos were at several sites. Winter Wrens and Sedge Wrens were in full song. And Yellow-bellied Flycatchers have returned to their bog breeding forests. Lincoln’s Sparrows sang from the scrubby taiga-like bogs.
