No…Not a Bison cow with triplets…Just two playful “red dog” calves coming over to play with her nursing calf. The Bison were just dropping their calves in late April.

Snow greeted us as we pulled in to the Mammoth Campground in Yellowstone after driving all night from Duluth. But as we waited for someone to vacate the campground so we could pick a spot, this male Mountain Bluebird entertained us by foraging near the gate.

Yellow-bellied Marmot. I like how the shade of the mountain slope in the background becomes a beautiful blue blur.

We were bummed that the road that leads to LeHardy Rapids was still snowed in. This is the traditional hotspot for Harlequin Ducks. But fortunately we spotted this colorful pair along the Madison River.

Harlequin Duck male spreads his tail feathers after preening. Yellowstone is the southernmost breeding site for this species in all of North America! The main part of their breeding range includes British Columbia, Alaska, Yukon and Labrador. They prefer to nest along fast-flowing mountain rivers.

Harlequin’s love fast water…the more turbulent the better! They dive underwater in rapids to feed.

We ran across a band of Bighorn ewes near Yellowstone Picnic area.

Bridget specifically said “No frosty Bison photos! You have enough of them” But this one is a bit different. I converted the image to black and white then clipped the whites and blacks of the histogram to make a more high contrast image. It more accurately reflects what I remember from the Bison encounter than the original image. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/250, handheld]

I used a long exposure on these Harlequin Ducks to allow the river to blur nicely. But you have to take many photos as the ducks were constantly fidgeting.

The two images above were taken early in the morning between Mammoth and Tower Junction. You don’t always need the sun at your back! Backlighting can really be quite dramatic. I love how the rim light defines the elk’s shapes and makes the spring leaves pop. Also keep in mind that shadows often show as blue to our cameras and it contrasts nicely with the green leaves. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/640, -1EV, handheld]

Did you do a double take when you looked at this image? This is a reflection of a Bighorn ewe that I flipped 180 degrees. Have fun and experiment! [Canon 7D with Canon 400mm f5.6 lens, f6.3 at 1/1250, handheld]

Shapes often tell as much of a story as detailed subjects. I underexpeosed by nearly two stops to get this silhouette of Ryan hauling his 600mm f4 on a tripod across the snowy Hayden Valley. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/6400, -1 2/3 EV handheld]

Our wildlife subjects don’t always need to be large in the frame. But we really have to work to remember this and actually shoot “animal in the landscape” shots. Ryan and I had followed (by car) this sow and second-year cub for a while, but they cut up this steep hillside. I turned the camera vertical to emphasize the tall trees. Her backlit breath was a bonus. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/500, handheld]

I rented the Canon 85mm f1.2 lens for this trip specifically to play with extremely shallow depth of field in wildlife photography. This lens is commonly used in portrait photography to achieve very shallow DOF. This obliging Raven allowed me to get quite close and the result is a unique critter image with only an inch or two of in focus bird.

This is a very different perspective on one of the most visited sites in Yellowstone…the Falls of the Yellowstone River. I set up my tripod back from the overlook and put on the wide angle lens. Then I attached a B+W 9-stop ND (neutral density filter to slow down the exposure in order to record the motion of visitors gawking at the falls (and taking selfies!). Of course, there were a dozen people here just before I got set up, then they all vanished. Where’s the bus of Japanese tourists when you want them!

Though the full moon ruined any plans we had for star trail photos, it made up for it during this moonrise at Silver Gate. The only way to get a large moon in your photos is to use a very long telephoto lens. But put an “earthbound” element into your photo to give the full moon scale.

Living in northern Minnesota, there are few ducks we don’t regularly encounter. But this May trip to Yellowstone National Park was special in that there I had a chance to photograph three species that I’ve never photographed before…Harlequin Duck, Cinnamon Teal and Barrow’s Goldeneye. All gorgeous western waterfowl that are rarely seen in the Midwest.

Harlequin Ducks at LeHardy Rapids on the Yellowstone River. I used a very slow shutter speed to make the water silky smooth but still wanted the ducks sharp. A different look. [Canon 7D with Canon 400mm f5.6 lens, f18 at 1/5, ISO 100, tripod]

Harlequin Ducks at LeHardy Rapids on the Yellowstone River. They sleep/doze in the middle of the rapids, all the while being splashed in the face with water! [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/60, tripod]

Harlequin Ducks at LeHardy Rapids on the Yellowstone River. I chose a slower shutter speed to highlight the color in the water. It took many frames but most of the Harlequins are fairly sharp. [Canon 7D with Canon 400mm f5.6 lens, f14 at 1/8, tripod]

Harlequin Ducks at LeHardy Rapids on the Yellowstone River. Harlequins are like “Dippers of the Duck World”…they dive and gather food underwater in fast moving rivers and rapids. Fun to watch them moving UPSTREAM in fast water. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/250, flash with Better Beamer, handheld]

Barrow’s Goldeneye in flight on the Yellowstone River. Not my best duck-in-flight shot…it’s turned away from me a bit…but my best Barrow’s Goldeneye flight shot! We have Common Goldeneyes in Minnesota. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/2000 (to freeze the wings in flight), handheld]

Cinnamon Teal male in the Hayden Valley. This was my closest and best sighting of a Cinnamon Teal ever! Gorgeous! I crawled over the snow to get close enough for a shot. Love the red eyes too. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/1600 (just in case he flew), handheld]

I was quite surprised to come across these two White-faced Ibis in an open stream in the snow-covered Hayden Valley. I did not know they migrated through the park. Strange to see a tropical looking bird in this mountain valley! They are gorgeous with iridescent green and burgundy plumage. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/1000, handheld]
