I head down to Crex Meadows Wildlife Area near Grantsburg, Wisconsin to search for my Lifer Olympia Marble butterfly. I also stumble upon one of the most beautiful turtles in North America…the Blanding’s Turtle (which promptly “mauls” me 🙂

Vesper and Grasshopper sparrows are singing, along with Eastern Towhees, Trumpeter Swans and Eastern Kingbirds.

It is hot, and the mosquitos are awful, but I find multiple species of butterflies to photograph including Hoary Elfin, Juvenal’s Duskywing, Silvery Blue, and, my main target, Olympia Marble…the butterfly that looks like its been brushed with gold foil!

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.

Usually I don’t recommend photographing birds while at the nest. This is especially true of songbirds who are easily disturbed and may even abandon a nest with eggs if the photographer is too intrusive. But woodpeckers are a bit more tolerant, especially once you can hear the young begging and calling from the cavity. At this stage, mom and dad are making frequent trips to the nest just to keep the babies full and happy. You don’t even need a blind as they will usually tolerate your quiet presence. But don’t overstay your welcome! A half hour to an hour or so is probably plenty. After that, the parents may become annoyed with the unwanted attention.

EQUIPMENT and TECHNIQUE
Ideally you’ll find a nest that is not too high in the tree. Eye-level would be wonderful but this rarely happens. Cavities up to about 20 feet in the tree are workable. Look for an angle that is more of a side-view than a straight-on shot that will only get you many “back shots.” Then look for an uncluttered background. For me the perfect scenario is a background mix of blue sky and green leaves that is a fair distance away so they blur nicely into green and blue blobs of color (see the Yellow-bellied Sapsucker nest photo below).
A flash is essential in many situations. Dappled sunlight is a very tough photographic situation and most nests are deep in the woods. A flash alone will be better than no flash, but a flash with a Better Beamer attached will throw your light much farther. Grab your tripod for rock solid shots. Since you know exactly where the action is going to happen, it is easy to set up your tripod/camera combo in exactly the perfect spot. Then, when a bird comes in, you don’t even have to look through the camera, just press and hold the shutter. And since with flash your shutter synch speed will likely be 1/200 or 1/250 of a second, the tripod will help keep your images sharp.

A Northern Flicker pair decided to nest right along our driveway this summer. And they chose an interesting site. They excavated a hole in a “widow maker” …a large branch that had broken off the main tree but was still hanging by a “thread.” But the branch stayed intact and they survived. It was fun to watch them feed the young ones. [Canon 7D with Canon 400mm f5.6 lens, f8 at 1/250 second, ISO 1600, Canon 420EX flash and Better Beamer, hand held]

Golden-fronted Woodpeckers are the southern cousin to our Red-bellied Woodpeckers. Note their golden yellow nape and the red atop the head (only the males show this mark).This male in a nest cavity in south Texas near the Rio Grande River was not calling, just yawning. Raising kids is tiring work! [Canon XTi with Canon 400mm f5.6 lens and 1.4x teleconverter, f8 at 1/125 second, ISO 400, -1.0 ev, tripod]

Thanks to Paul Sundberg for sharing this Pileated Woodpecker nest location a few years ago. It was in a very photogenic Paper Birch too! Look closely and you can see that the male (red “mustache”) is doing some “house cleaning” by removing the young’s fecal sacs from the cavity. He will fly off and dump them away from the nest so as not to advertise its location to predators with a pile at the base of the home tree. [Canon XTi with Canon 400mm f5.6 lens, f5.6 at 1/640, ISO 400, Canon 420EX flash and Better Beamer, tripod]

Male Pileated feeding the crew. The female lacks the red “mustache.” Abandoned Pileated nest cavities (the birds never reuse a nest hole) are readily adopted by many species including Flying Squirrels, Red Squirrels, Pine Marten, bats, nesting ducks (Wood Ducks, Common Merganser, Hooded Merganser, Bufflehead), nesting owls (Boreal and Saw-whet), other woodpeckers (Hairy, Northern Flicker) and Kestrel. Pileateds are true “keystone” species in the North Woods…a species that is very important to the habitat and to many other species.

A few years ago we had a nesting Yellow-bellied Sapsucker near the house. This female (no yellow on throat) brings a beak full of ants to the youngsters. I like how the blue sky and green leaves background blurred in this shot. A Better Beamer on my flash lit up the bird nicely.

A juvenile Hairy Woodpecker boy begs from his aspen home (aspen tree, not Aspen, Colorado!) Baby woodpeckers can be LOUD when hungry. This is usually how I find the nest cavities.

The Northern Flicker was actually my “trigger bird” many years ago. A trigger bird is the one that got one excited about birding. As a kid I was a fanatical collector of many things—baseball cards, beer cans, barbed wire, to name just a few. When I was 13 I saw a strange bird land on the light pole in front of our house. It had many field marks—spots on the breast, a red mark, a black “moustache”, and lots of yellow. I somehow found out it was a Yellow-shafted Flicker (now called Northern Flicker) and I wondered how many other birds were around. I basically started “collecting” bird sightings. This led to a lifelong fascination with birds, and eventually wildlife photography. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/640, ISO 1000, braced on car window]

My flash had run out of batteries and dusk was approaching, but I didn’t want to miss the shot. What to do? I simply cranked up the ISO to 3200 and kept shooting. I was even able to freeze the action as this Flicker fluffed her feathers. Sure its “noisier’ than if I would have shot it at ISO 200, but I still got the shot.

Black-backed Woodpeckers are a bird of remote boreal forests. Then NEVER come to bird feeders and rarely leave their Black Spruce/Tamarack bogs. You can usually tell their cavities by the ring around the hole that has been completely debarked. This female is feeding a young male (note his yellow cap). Interestingly, the following year another Black-backed nest was occupied just above this one in the same Tamarack. Was it the same adults? Or one of the offspring? Black-backeds often nest in living spruce, tamarack and pine near water or other openings in bogs, burns, and upland spruce-fir forests.

I photographed nearly 250 species of birds in 2013…and it is always fun to look back over the year and pick my favorites (BTW I discovered that I kept nearly 10,000 bird images taken in 2013…And this is even after I deleted at least that many from my memory card before ever downloading). Most were taken very close to home in Carlton County, Minnesota. In fact, 15 were taken within 60 miles of home and 3 of those were taken on my land, and 2 were taken right from my living room! Only two images were taken outside of Minnesota…the dowitcher in Wisconsin and the oystercatcher in Florida. Previously I posted some of my favorite bird action shots. and Top Ten Creative Wildlife Shots. Here are my favorite bird portraits from 2013.

April was a brutal month in northern Minnesota…Over 48 inches of snow in April alone! This photo exemplifies the mood of the month. This early-returning Yellow-rumped Warbler seems disgusted to find spring not yet sprung in the North Woods. Fortunately, these insect-eating birds will also feed on suet, which we had plenty of. Taken from my living room easy chair! My house, Carlton Co, Minnesota.

Amazingly, several of my favorites of the year were taken through our living room picture windows. This Wild Turkey tom had love on his mind in mid April and here he is showing off to the half dozen hens that surrounded him. See more photos and video here. My house, Carlton Co, Minnesota.

Just a nice simple portrait of a White-throated Sparrow. I brought these lichen-crusted rocks back from Wyoming just for this purpose. I placed them on my picnic table, then put out cracked corn for the migrating sparrows and blackbirds. My blind was 20 yards away. I could sneak in there for brief sessions before dinner when the light hit the table just right. My house, Carlton Co, Minnesota.

What I like about this photo is the graphic element of the vertical grass stalks with the Swamp Sparrow relatively small in the frame. Felton Prairie, Western Minnesota.

It’s not often that a shorebird allows your close approach…but this Short-billed Dowitcher did. I was able to sloooowly get out of my car and ease myself into the shoreline brush to get a closer shot. It was late in the fall migration so the dowitcher was very intent on feeding, gathering energy to continue its journey south. Crex Meadows, Wisconsin.

Early morning light on one of our most spectacular ducks—the Northern Shoveler. It is named for its oversized bill that is used to sift pond waters for micro-organisms. See more Felton Prairie shots here. Felton Prairie, Western Minnesota.

Ice-out was very late in spring 2013. This can be good for photographers as it forces spring-migrating waterfowl to the open water close to shore (where the ice melts first). This Horned Grebe really had its “horns” up, and was in peak spring plumage. Love the red eyes too! Park Point, Bayside of Lake Superior, Duluth Minnesota.

This is actually a single frame from a clip of video I was shooting of this Great Gray Owlet. Because of that, the file is quite small and of limited use. I just like how the little guy was stretching its wings over its head.

See the full story and video of this amazing experience here.

The two images above were from June when a friend of mine, Kim Risen, discovered a Great Gray Owl nest deep in a Spruce-Tamarack bog. The young had fledged but were still begging to be fed by mommy from their ground perches. I crawled slowly up to them with my wide angle lens and flash, took a few shots, then crawled away again. Mom supervised the whole operation. Northern Minnesota.

I just like the vertical composition of this image. Tamaracks turn a vibrant yellow-gold in the bogs of October and this Gray Jay made one his tip-top perch. Sax-Zim Bog, Minnesota.

Another Sax-Zim Bog photo. I like this image because it is our two species of chickadees together on one branch. The Boreal Chickadee is restricted to deep dark Black Spruce/Tamarack bogs while the Black-capped is found in nearly every habitat in the North Woods. Boreals are more attractive in person than they are shown in the field guides; I love their warm brown cap and olive back. Amazingly they do not eat sunflower seeds! In fact, at this feeder (Admiral Rd in the Sax-Zim Bog) they only feed on suet and peanut butter—Fat! In the bogs they feed on insects (eggs, adults, larvae) and carcasses. It is my belief that if enough of them could gang up, they’d bring down a Moose! Feast time! But seriously, they do not readily leave the Black Spruce/Tamarack forests and are never seen at feeders away from their bog security blanket.
[Taken at Admiral Rd feeders in the Sax-Zim Bog. I set up the branch and put some peanut butter behind the branch to attract the chickadees. Canon 7D with Canon 400mm f5.6 lens, Canon 420EX flash with Better Beamer.]

Brewer’s Blackbirds are actually anything but black…In the right light, their iridescent feathers show purples, bronzes and greens. A weathered fence post and rusty barbed wire adds to the prairie feel. See more Felton Prairie shots here. Felton Prairie, Western Minnesota.

The winter of 2013 brought birders and photographers a special treat…an irruption of a rarely seen owl called the Boreal Owl. About the size of a small box of Kleenex, the Boreal Owl preys on voles but when vole numbers crash in areas north, they must move south in search of food. This little guy was photographed on an overcast day. It was a big surprise when I saw the image on the computer…I loved how the tree trunk’s lichens blurred to pleasing shades of green, and was especially excited about the oozing sap/pitch that turned blue in the shade, both contrasting nicely with the Boreal’s yellow eyes. See more of my photos and video of the irruption here. Near Stoney Point, Duluth, Minnesota.

It was a Boreal Owl irruption winter…the first in many years. The hungry owls had been driven south in search of food and ended up along the North Shore of Lake Superior near Duluth. The event was a treat for birders and photographers but was an ordeal for the owls. Fortunately, many seemed to be catching voles despite the deep snow. See more of my photos and video of the irruption here. Near Stoney Point, Duluth Minnesota.

During a spring family outing to the Duluth Zoo, we stumbled on a very wild and non-captive flock of Bohemian Waxwings. The birds were happily feeding at head-height in a crabapple tree near the Siberian Lynx and Snow Leopard. I shot the birds as folks walked right by the tree without even noticing the birds (until they looked at me and wondered what I was photographing.) Duluth, Minnesota.

A family vacation to Ft. Meyers Beach, Florida in June was filled with fun but cursed with bad weather (The kids didn’t even notice!). So when I took this shot of a Black Oystercatcher on a tidal shallow pool under heavy overcast skies, I didn’t think much would come of it. But when I got back home and saw it on the computer, I was ecstatic. The gray water and flat light actually work in this case. I blew out the whites to give the Oystercatcher a nice clean background. I love the curved sweep of its feathers as it preened. See more photos from the Florida trip here. Fort Meyers Beach, Florida

Bald Eagles often survive northern Minnesota winters feeding on roadkill White-tailed Deer. This one was doing just that. Can you see the blood on its bill? Carlton County, Minnesota.

Every few years a flock of American White Pelicans stops by the St. Louis River near Fond du Lac, Duluth Minnesota. They usually spend a few weeks loafing, preening and fishing in a stretch of river near the bridge. They are always a blast to watch and I really enjoyed an afternoon with them in May. Fond du Lac, Duluth, Minnesota.
