Yellowstone Diary: May 16, 2012

We work hard at getting lucky.  Although Yellowstone is home to a grand abundance of wildlife, this is not a zoo.  Viewing the park’s animals takes knowledge of their behavior, both as species and individuals, perseverance, and luck, lots of luck.  The result, recorded here, is an example of  just how much can be seen in a single day when all elements of the effort are working in your favor.

We began the day with a plan to revisit the area between Mammoth Hot Springs and Norris.  Just south of the Grizzly Lake Trailhead we found the black bear that we had seen on the previous afternoon.  A bit further along the Grand Loop Road along the way we encountered a small group of bison near Obsidian Creek.

The images above and below were recorded at 07:40, using the Nikon D4 and the AF-S NIKKOR 200-400mm f/4G ED VR II at either 270mm (above) or 330mm (below).  Exposures were at f/8.0 and either 1/800s (above) or 1/1250s( below), with ISO at 1600.

From the Norris Junction we headed east to Canyon Village to shoot the Lower Falls of the Yellowstone River from Artist’s Point in the morning light.  The two images below were recorded 08:30 MDT using the Nikon D800E,  and either the AF-S NIKKOR 24-70mm f/2.8G ED at 82mm with and exposure of f/11.0 and 1/100s (+0.33EV), ISO 100 (top) or the AF-S NIKKOR 70-200mm f/2.8G ED VR II at 200mm.  Exposure were f/11.0 and 1/100s (+0.33EV), or f/8.0 and 1/320s (+0.67EV).  ISO in both cases was 100.

I’ve shot the falls many times in all kinds of light and atmospherical conditions.  Two elements are required for a memorable image – the direction and quality of the light are key of course, but of nearly equal importance is the sky region along the plateau at the top of the image.  It’s not bad here, there is at least a bit of color and texture, but not too spectacular either, and thus the relatively tight crop.

From Canyon we headed south through the Hayden Valley to Fishing Bridge – no animals along the route.  We then set out eastward towards the East Entrance, and found a small group of Bighorn Rams along the north side of the road where the East Entrance Road tracks along Middle Creek.  There were approximately six animals in this groups, foraging just 30-50 meters above the roadway.  They wouldn’t have given us the time of day…

The five images below were recorded using the D4 and AF-S 200-400 at various focal lengths.  Exposures were all at f/8.0 with shutter speeds clustered around 1/1600s, with ISO at 1600.

I also shot this same group of rams with the D800 and the 200-400mm (the original VR) at 400mm, with example images shown in the three shots below.  Exposures were at f/5.6 and 1/1600s, ISO 1600.  Although I hesitate to reveal it since it seems unlikely, but head-to-head at ISO 1600, the D800 has a clear IQ edge over the D4- the dynamic range of the D800 sensor is stellar.

We returned along our outbound route north though Canyon Village, and westward to Norris Junction, and back north to Mammoth.  We then turned west again to investigate the Blacktail Deer Plateau and the Lamar Vallay on the way to the northeast entrance of the park.  Along the way we found a very-well habituated Coyote at around 14:20 MDT.  The three images below were recorded using the D4 and the 200-400mm VR II at 400mm.  Exposures were at f/8.0 and 1/1600s, ISO 1600.

We continued on eastward and found the young moose from the previous day near the Icebox Canyon signpost – right out along the northern side of the road out in the open.  The image below was recorded at 15:42 MDT using the D4 and the 200-400mm VR II at 400mm.  Exposure was f/8.0 and 1/250s, ISO 1600.

 On our return back to Mammoth through the Lamar Valley, we encountered two rangers in the process of relocating the carcass of a bison calf from a spot about 50 meters from the road up over a bluff so it would be out of direct site of the highway.  We watched as the two rangers went up the hill – one ranger lead the way up the hill armed with a shotgun, and the other carried the carcass.  More on this rarely observed ranger activity in a future entry…  The image below was recorded at 16:30 MDT using the D4 and the 200-400 VR II.  Exposure was f/8.0 and 1/2500s, ISO 1600 – yeah the light was changing really fast at this time, thus the kooky exposure parameters.

Traveling further west along the Northeast Entrance Road we found a small group of pronghorns crossing the road near the base of Specimen Ridge.  I am uncertain about whether the roads in Yellowstone are de-iced with salt, but this would explain the curious behavior of the three animals in the second image below.  Images of the pronghorns were made at 16:50 MDT using the D4 and the 200-400 VR II at 220mm (top) and 400mm (bottom).  Exposures were at f/8.0 and 1/1250s, ISO 1600.

We continued westward to Mammoth Hot Spring, and then south with the idea to make one last visit to Norris that day.  Lounging bears in Swan Lake Flat caused us to change our plans…  Images of bear recorded at 17:50 MDT using the D4 and the 200-400mm VR II at 400mm.  Image of photographers made at 200mm.  Exposure were made at f/5.6 and 1/320s, ISO 1600.

Yellowstone Diary: May 20, 2010

The images above of a coyote executing effective  mousing technique were recorded at around 12:00 on May20, 2010, using the Nikon D3s and the AF-S NIKKOR 200-400mm f/4G ED VR lens at 400mm.  Handheld.  Exposure was f/8 at 1/2000s, ISO 1600.  I see that you think that perhaps 1/2000s was overkill…  Spend a few days shooting wild critters and you’ll come around.

The rain abated long enough for us to make a run for Artist’s Point to record images of the Grand Canyon of the Yellowstone River.  It’s simply an awesome location – easily as elegantly beautiful as the, well, real Grand Canyon, without the hoard (but do note the time of year).  Do not miss this.

Finally, and as promised, the now long-awaited story of the incident at Blacktail Lakes…  Driving back westward from the Lamar Valley we encounter a traffic jam at Blacktail Lakes.  As I run the truck up slowly behind the jam, we hear the unmistakable call of the wolf : Loud, solo, and clear.  Then other members of the Blacktail Wolf Pack respond, and soon a cacophony of howls and barks fill the air.  Spooky in a kooky species-memory sort of way, and unforgettable.

The sow bear and her big cub were defending the carcass from nine members of the Blacktail wolf pack.  Four wolves remain close to the bears, menacing and harassing them continuously.  Three other members of the pack pose a little further away, and two more a bit further yet.  The interaction of wolves and grizzlys is as wild as it gets I suspect.  Griz may be the king of the park, but the wolves haven’t got the news, and most probably couldn’t care less.  The wolves are interested in the protein, and apparently being no more particular about the freshness of said protein than Griz, they aggressively challenge the bears for the chance to feed upon it.  The bears are powerful and quick.  The wolves are less powerful, but smarter, well-organized, and quicker.  Its facinating to see how the skill sets interact.

The bears become agitated with the presence of the wolves, and occasionally turn and charge them as shown in the image below.  The wolves give up only minimal ground and return to close proximity as soon as the bears turn back to the carcass.

As remarkable as it was to view this remarkable interaction, things got even more interesting.  A third bear descended post haste upon the ponds from the high ground to the north.  Watching this animal descend the hillside provided clear evidence in support of the adage that you cannot outrun Griz – not a chance, not even close.  This larger animal intimidated the sow and big cub, who moved off the carcass without putting up any sort of protest (see below).

The bear does most of the feeding, that is certain, but by my conservative estimate, Ursus Actos Horibilis get nipped in the backside about every 30 seconds for the privilege.  Dude, those wolf bites are gonna smart some in the morning…  When the bears do finally get their fill, the wolves were on site to consume everything left.  Curiously, I never saw a wolf or coyote venture into water, not even paw-deep.  Canids generally seem to tread water without fear, members of  Canis lupus familiaris even seem enjoy a good swim, so it is a little odd that the wild cousins are apparently hydrophobical (hee hee).

Images of Grizzlies and the Blacktail Wolf Pack were recorded at between 21:00 and 21:30 MDT using the D3s and the 200-400mm lens at 400mm.  Yeah, that was around 21:00.  Checking the almanac, sunset was at 22:00, but with the overcast sky, it seemed much darker than anticipated.  Exposure was in the range of f/5.6 to f/8, with shutter speeds in the range of 1/5s to 1/15s, with ISO set at 25600.  Being able to recorded images under such low light is excellent, but there are issues.  Chief among them are WB and apparent exposure level.  As the images above reveal, I am still experimenting with WB.  Auto WB produces images that seem too blue-green, but what do we think is appropriate? Right now I’m thinking that late evening coloration might be best.  Ditto on the apparent exposure.  I’ve also been experimenting with BW conversion – stayed tuned for some examples.
