Finally finished editing my video of a Bobcat in Carlton County in northern Minnesota. See the previous post for photos from this once-in-a-lifetime encounter at a friend’s cabin. I said it before, and I’ll say it again…truly a beautiful cat! Enjoy!

CALLING IN A CANID
I drive over the bridge spanning the St. Louis River at Fond du Lac/Duluth (MN) at least 4 times a week, and I always check for eagles, otters, or whatever else might be utilizing this wild stretch of river. A couple days ago, I spotted something running along the far shore…but I was driving and it was so far away that I couldn’t tell if it was an otter, fox, coyote or wolf. I stopped and backed up so I could get the binoculars on it. But it was gone. Not sure why, but I decided to give a few calls on my Johnny Stewart predator call (that I always keep in my car). Almost instantly a Coyote came around the bend in the river, running towards the bridge on the frozen river.
I hustled back to the car, grabbed my camera with 400mm lens (which is also ALWAYS in my car) and hid behind the snow bank up against the bridge railing. Conveniently there was a hole in the snow bank where I could look through the bridge railing. She was coming fast and I tried to start shooting but my lens had frosted over. Frantically I tried to scrape the ice off the front of my lens with my glove (not usually a recommended practice!), then I tried shooting again but the lens would not focus! I found that I had the camera set to AI Servo focus mode and quickly switched it to Single Shot focus, which worked. In the process, I had breathed on the viewfinder and fogged it up…And now I couldn’t find the Coyote while looking through the camera! All this happened in a few seconds and by now the Coyote had slowed to a trot. I gave a few more calls (imitating what, I’m not sure!). A quick swipe of the viewfinder allowed me a passable view and I quickly started shooting, trusting that my autofocus was doing its job!
Well, that Coyote never saw me and came to a stop right underneath me, trying to figure out where the “wounded rabbit” was. I couldn’t resist a couple shots looking straight down on her from 40 feet above (NOT a good angle for wildlife photography!). And as I peeked over the top of the snow bank, she saw me and trotted off, turning back a couple times to make sure she hadn’t missed an easy meal. I really wished I had a dead rabbit to throw to her. As you can see, she was a beautiful animal. (Not sure if the Coyote was a male or female, but I choose to call it “her”)
[Taken looking straight down from the bridge…40 feet (?) above the river]
SHUTTER PRIORITY SURE THING
This was the perfect scenario for shooting with Shutter Priority. It was fairly early in the morning and overcast. I knew I wanted sharp Coyote images. If I’d had my camera set to Aperture Priority, I may have ended up with slower shutter speeds and the Coyote would be blurred. Yes, the image might be less “noisy,” but I’d rather have a sharp, useable, noisy image, then a blurred, un-useable, cleaner image that I’d delete anyway. So I set the camera to Shutter Priority 1/400 second (a compromise, to be sure, as it would freeze a walking/trotting Coyote but not a running Coyote) and Auto ISO. The camera automatically keeps the aperture at f5.6, 1/400 and lets the ISO range up and down…In this case from ISO 1000 to 1600. These settings allowed me to get sharp images in low light. This portrait was taken at ISO 1600 on a Canon 7D—a camera not known for its high ISO capabilities…and you don’t even notice the digital noise.
When I got home that evening, I calculated that the Coyote had heard my mouth call from 1/3 of a mile away! Never underestimate the senses of wild critters…Deer hunters know this very well! I do feel bad that this Coyote expended energy on a “wild goose chase,”…and I will not use this call on a Coyote in this area again this winter. I really only use the Johnny Stewart predator call when I see a critter duck into the woods and I try and get them back out into the open. My success rate is probably 2 to 5%.
HIGH KEY IMAGES
In these two images, I blew out the whites in Photoshop. I didn’t really need any detail in the snow and I like the look. So I moved the right slider in the Levels palette to the left until it completely clipped the whites.
[ALL IMAGES: Canon 7D, Canon 400mm f5.6 (handheld but braced on snowbank), Tv (Shutter Priority) 1/400 second at f5.6. Auto ISO (ISO ranged between ISO 1000 to 1600 for these images)]
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
Note 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.”
On 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.
STREEEEETCH! 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].
Though 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.
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.
Eye-level shot with Canon 400mm f5.6. I WISH I’d put my big flash and Better Beamer on! The images looked okay on the LCD but there is a weird greenish cast from the light filtering down through the canopy. Live and learn!
The 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!

Last year I got the “Trifecta of Mega Moths” …Cecropia, Polyphemus and Luna; But this year I added the Promethea to get the GRAND SLAM!
All were photographed between my house and garage. My technique is simple…Leave the garage light on all night then go out in the morning and try (emphasize the word “try”) to move them gently to a more photogenic perch. You have to go out very early (5:30 to 6:30 am) before they warm up and fly off.
CECROPIA (Hyalophora cecropia) The genus is named after Cecrops I, the mythical first king of Athens, and it is certainly the KING of North American moths…It is one of the showiest and largest with a wingspan approaching 6 inches. Caterpillars are especially fond of maple leaves but also feed on tamarack, spruce, birch and cherry. Sparse population in the “wild” as there may only be a couple adults in a square mile of forest, BUT some residential populations can be quite dense. Males may FLY 20 MILES (!) over several nights, and mate with several females.
LUNA MOTH (Actias luna) Luna the Goddess, was the ancient Roman divine personification of the Moon. Caterpillars much prefer the Paper Birch leaves in the north woods. This is my best Luna photo in a long while…Unfortunately it is on the T-111 siding on my garage. When I tried to move it, it started its flopping-Arching defense and escaped.
PROMETHEA (Callosamia promethea) Prometheus, a Titan, culture hero, and trickster figure who is credited with the creation of man from clay, and who defies the gods and gifts humanity with fire” (Wikipedia). Adults live for a week and may fly 20 miles in that time period. This is a female but the darker male is day-flying and may mimic the unpalatable swallowtail butterfly. Caterpillars feed on black cherry, ash and perhaps, lilac.
POLYPHEMUS (Antheraea polyphemus) Polyphemus is the gigantic one-eyed son of Poseidon and Thoosa in Greek mythology, one of the Cyclopes. And a semi-appropriate name as this huge moth shows one striking “eye” on each hindwing. The thought is that bird predators will attach the false eyes on the hindwings and do little damage to the moth itself. Caterpillars feed on birch, maple, willow and oak.
HOME MOTH PHOTOGRAPHY TIPS
1. Leave a garage/exterior house light on overnight (but don’t overdo it…leave the light off for a couple of nights between sessions, otherwise Gray Treefrogs, squirrels and birds will feast on your moths at dawn)
2. Go out early and see what the light brought in. Get outside between 5:30 and 6:30am before the moths warm up and start flying away.
3. Take “record” shots of moths perched on your garage or house siding, or porch. Then try to move them to better perches using native plants, trees. I slowly slip a flat piece of wood (about the size of a shim) under the moth until it clings to it. Then I move to my backdrop of choice and ease them onto that.
4. I have my flash and basic exposure set already…You can use a pop-up flash or hot-shoe flash, but you really should use some flash to make your subject pop.
5. I like to set a manual exposure that keeps my shutter at between 1/160 and 1/250 when using the pop-up flash (which synchs at 1/250 max). Sometimes, for larger moths, I can use my hot shoe flash set to Hi-speed synch to get higher shutter speeds. Remember, much of your shooting will be early in the morning and you may have to crank up the ISO to get these shutter speeds.
6. Now here is the part that has really improved my moth/insect shots..I switch the camera to live view and manual focus. Now when I see my favored composition in the viewfinder, I magnify the live view to 5x power. I now simply move my body/hands/camera in and out until the key part of the subject is razor-sharp in the live view viewfinder and click the shutter. I guarantee this technique will improve your moth and insect images!

FLORIDA. I wish I could post the full-size photo of this panorama combining 4 images in Photoshop…It is 45 inches long! …and very sharp. Taken during a brief appearance of the sun near sunset along Fort Myers Beach. Handheld with the Canon 400mm f5.6 lens.
The above images were just “G&G” images for me (“grab-and-go”)…I was walking the Estero Beach Lagoon when I saw these AMERICAN OYSTERCATCHERS lolling about. I didn’t put much effort into stalking them or even setting up my tripod because the light was FLAT and the only background was blah, colorless white water. Not a very interesting background. BUT when I got home and looked at these on the computer, I knew that they were my best photos of the trip. I really like the monochromatic water background…It is a nice contrast to the brown-black and orange of the oystercatcher. By the way, yes, oystercatchers do “catch” and eat oysters! (and many other bivalves including mussels and clams)
What a great name!…MAGNIFICENT FRIGATEBIRD. For me the name conjures up visions of the Caribbean and the tall ships that plied these waters centuries ago. An early naturalist likely noted that the birds often came to rest on the masts of these vessels far from any land and named them “frigate birds.” These are HUGE seabirds that effortlessly float in the sky, gliding on stiff Caribbean winds, wings that span nearly EIGHT FEET(!) firmly set. They can glide like this for HOURS, never once flapping their wings. You’ve probably seen them in some nature program before…They are the birds with the red air sacs on their throat that they inflate like a balloon during breeding and courtship. But on this trip I only managed a few flight silhouettes, distinctive as they are, under gray sky conditions. But I decided to get creative and combine 5 images of the same bird into one, making my own flock of five flying frigatebirds (say that 3-times fast!). A dramatic increase in contrast helped the final image pop.
In the North Woods of Minnesota, we rarely get to see a Great Egret (found south in the state) and NEVER get to see them with their breeding plumage including their green facial skin. Snuck up on this guy at Estero Beach Lagoon.
SANDWICH TERNS always remind me of my birding friends Parker Backstrom and Don Kienholz. Back in the mid 80s they were birding the Duluth Port Terminal on a gray, rainy, foggy May day when they spotted a strange tern with a yellow-tipped bill. It was a very-far-from-home Sandwich Tern, and a first state record for Minnesota! Dirt common in Florida as they hunt (fish) the ocean shorelines for small fish, plunging beak-first into the water.
LEAST TERN is the smallest and cutest tern in North America. I completely associate it with the Gulf Coast but amazingly, they also nest on braided, sandbar stretches of the Upper Missouri River in South Dakota (only an hour SW of the MN border), North Dakota and Montana.
SNOWY EGRET stalks critters along a busy Fort Myers beach. I didn’t think much of either of these photos UNTIL I made it a “HIGH-KEY” image, overexposing, and even blowing out completely the whites. I like the monochromatic effect and the contrasting black bill, legs and yellow feet.
Who doesn’t love pelicans? And BROWN PELICANS are the native pelican in Florida. This adult was lazily flying along the beach, but would then suddenly plunge head-first into the surf and more often than not, come up with a fish in its pouch.
COMMON GROUND-DOVES, like many of North America’s doves and pigeons, are taken for granted. But when you really study them, many have quite beautiful plumages, some with delicate scaling and subtle iridescence. This dove is native to the southern fringe of the U.S. from South Carolina to Florida to Texas, Arizona and S. California. When it flies, it reveals its stunning rusty red underwings.
A lifer TIGER BEETLE! This beach tiger was a new one for me—Cicindela hamata lacerata. I love tiger beetles! Fast and furious, they pursue insect victims, pouncing on them in lightning fast attacks. And it really helps to be colored like the sand you hunt on.
Funny story…WILSON’S PLOVER is a sand-colored shorebird restricted to the South Atlantic and Gulf Coast states, Virginia to Florida to Texas, BUT I’d just seen one the week before on Minnesota’s own version of an ocean beach—Duluth’s Park Point on Lake Superior. My friend Karl Bardon had found this lost wanderer, only Minnesota’s THIRD state record. Interestingly, I myself had found Wisconsin’s FIRST STATE RECORD of this species back in 2004(?) and just a few miles from here on Wisconsin Point. Anyway, good to see a Wilson’s in its native habitat for a change!

First of all, let me say that Boreal Owls are the cutest bird in the entire world! About the size of a Kleenex box, nearly as wide as they are tall, the Boreal has bright yellow eyes with two black “tear drop” marks and a face framed by black. Immaculate white spots dot the forehead. This has been a great winter to see this most elusive of all owls in northern Minnesota.
Roughly every 4 years there is an increase in Boreal Owl sightings in Minnesota. Usually, late in the winter, a few may be spotted hunting in the daytime, which often means that they are hungry!…possibly starving. You see, Boreals are normally nocturnal hunters. So when voles are at a low cycle further north, the Boreals need to move in search of food. In late January of 2013 they started showing up in Sax-Zim and along the North Shore. Guide Chris Wood found SEVEN in one day along the Scenic 61 highway north of Duluth. This has been a huge IRRUPTION! (yes, irruption is the right word).
And since Boreal Owls are rarely seen, this influx of day-hunting Boreals is big news. Most of the folks I guide still need it for their life list. So irruption years become BUSY years for the local guides (and I’m no exception!). In fact, the tiny owl hadn’t even been recorded nesting in the Lower 48 until the spring/summer of 1978 when a Boreal Owl pair took up residence in a nest box in Tofte, Minnesota.
Here is a compilation of video from 4 different Boreals taken between January 27th and February 8th.
All photos taken with Canon 7D and Canon 400mm f5.6 lens. BUT note that the top photo was taken with the 400mm AND stacked 2x and 1.4x teleconverters! Don’t let anyone tell you that you should NEVER stack teleconverters…I did and the photo turned out all right I think.
The search pattern one develops while looking for wildlife in Yellowstone, is to carefully scan the roadside…not for critters…but for parked cars! A car pulled off to the side of the road usually means there is a critter someone has spotted. One evening, while returning from a trip to the southeast entrance, we saw several vehicles pulled onto the shoulder. We slowed, but assuming it would turn out to be a Bison, we expected to just cruise on down the road…
“Grizzly!” We gushed in unison…a very good find. And the Griz was in beautiful evening light. Unfortunately (or fortunately) the bear was about 170 yards away…a safe distance to be sure, but a little too distant for a straight 400mm lens. Thankfully Ryan (www.irentphoto.com) had loaned me a 500mm f4 lens, onto which, I put a 2x teleconverter. This combo on the 7D created a 1600mm lens equivalent (Some of the video was shot with TWO 2x teleconverter, AND a 1.4x teleconverter, creating a 4480mm lens!! Not the sharpest video in the world..but useable.)
As is often the case with Yellowstone Grizzlies, this bear was so intent on feeding that he rarely even stuck his head up for more than a few seconds every few minutes. He was actively digging for tubers…and with winter coming on fast, he had no time to lose in fattening up.
Here’s a video of “Teddy” the Grizzly digging tubers…Not very exciting but this is what Grizzlies do 90% of their waking time…EAT! Especially important since he would soon be going down for a long winter’s snooze.
What is the diet of a 300lb. to 600lb. male Grizzly in Yellowstone? According to the park’s website…”From September through October, whitebark pine nuts are the most important bear food during years when seeds are abundant (Mattson and Jonkel 1990). However, whitebark pine is a masting species that does not produce abundant seed crops every year. Other items consumed during fall include: pond weed root, sweet cicely root, bistort root, yampa root, strawberry, globe huckleberry, grouse whortleberry, buffaloberry, clover, horsetail, dandelion, ants, false truffles, and army cutworm moths. Some grizzly bears prey on adult bull elk during the fall elk rut.” So Teddy was likely digging for either yampa root, bistort root or sweet cicely root.
