Bighorn Picnic

The most common question asked of rangers in Yellowstone National Park?  Number one would definitely have to be ‘Where can we see _______?  The most popular fill-in-the-blanks being bear and wolves in that order (or perhaps the reverse), with bighorn or moose vying for position three.

If the blank gets filled in with bighorn, then the answer invariably is ‘Yellowstone Picnic Area’.  Not only is this one of the most popular picnicking spots in Yellowstone, but it is also the most popular location from which to view bighorn sheep.  The site; which is properly known as the Yellowstone River Picnic Area, is located about 1.2 miles east of Tower Junction along the NE Entrance Road, and has nine tables and a restroom (separate M/W, pit type).

The location is the big seller here – as the name of the site indicates, it is located next to the Yellowstone River at a point where the river emerges from deep canyon walls in more open terrain.  One can walk south about 0.1 mile, ascending higher ground to a river overlook, or walk westward down-slope to gain river access after about 0.3 miles.  Alternatively, although not technically part of the picnic area, there is a parking area just above the river at a point approximately 0.3 miles west of the picnic area (or 0.9 miles east of the Tower Junction) that provides easy access.

Images in this entry were recorded on May 20, 2011, at 13:00 MDT, using the Nikon D3s and the AF-S NIKKOR 200-400mm f/4G ED VR II lens at various focal lengths.  Exposures were all at f/8.0, with shutter speeds in the 1/1000s range, and with ISO values near 1250.  I would generally make an effort to shoot big game animals using an aperature of f/5.6, e.g., to isolate the subject from the background.  However, as this group was moving around quite a bit, I was a little worried about the subjects passing out of focus before I could get the shot off and worked at f/8.0.  Also, the background in most of the shots shown here was sufficiently far off that I though it would be out of focus at f/8.0 anyway.

Capture, creative, and output sharpening was applied using Photokit Sharpener 2.  Images were converted using ACR 6.6.  Processing consisted of curves adjustments to the red and green channels to enhance contrast, followed by additional contrast, saturation and microcontrast (Structure) enhancement using Nik Viveza 2, and Tonal Contrast adjustment using Nik Color Efex Pro 4.

Note that the picnic area is located just a bit low of the center, where a couple of vehicles are visible.  The parking area is located a bit high of center, where there appears to be a single vehicle parked.

One Grizzly Specimen

Okay, so it’s a code…  Grizzly Bear obviously, but the specimen bit refers to the location at which we found this, well, specimen, of Ursus arctos horribilis.  Said location was indeed on the lower flanks of Specimen Ridge in Yellowstone National Park.  Griz can frequently be observed higher up on this massif, in or near the treeline, but rarely right along the Grand Loop Road, which is where we encountered this animal.  A land shark on patrol in a sea of sage.

BTW, this is too close.  The EXIF data recorded that the subject distance for the image above to be about 40 meters.  I seriously doubt the data, since as I recall, the distance seemed more like 40 feet…  Park regulations specify that ‘Approaching on foot within 100 yards (91 m) of bears or wolves or within 25 yards (23 m) of other wildlife is prohibited.’  Park regulations do not specifically address what happens when the wildlife approach you, but retreat whenever possible is naturally the best course of action. In this case, we were definitely retreating while the shooting continued.

Some folks believe that the taxonomic designation for Griz is unfair to the nature of the animal.  I dunno, but if you were standing as close as we were when this image was recorded, I’d bet you would agree that U. a. horribilis is pretty much on-target.  A most impressive creature, huge but remarkably agile, and definitely worthy of respect. As the bear strode past us, we had a rare opportunity to observe just how powerful this creature is.  I’d estimate that the strolling bear was moving a pace well above 5 mph, and that a person would have to jog at brisk pace just to stay ahead of the bear.  We’ve seen Griz move at full speed too, which is a bit better than 30 mph (for an average bear that is).  Compare that speed with that of the fastest humans, who move along at just over 20 mph, and you get an important suggestion – don’t get into a foot race with Mr Speedy.

Images in this entry were recorded at around 13:00 MDT on May 16, 2011 using the Nikon D3s and the AF-S NIIKOR 600mm f/4G ED VR lens.  Exposures were f/8.0 and either 1/1000s or 1/1250s, ISO 1600.  I’d have liked to use a larger aperture, but the bear was moving so swiftly towards us that I thought it best compromise in favor of just a bit more DOF.  Was 600mm necessary?  Yeah, absolutely no doubt.  I do get a lot of comments in the field… ‘Boy, I bet my pictures would be a whole lot better if I had *that* lens…’  Well maybe, and while I’m definitely privledged to be able to get my mits on the lens, I issue the fair warning that using big glass effectively is one helluva lot harder than it looks…

A Trickster in Hayden Valley

A number of native American Indian cultures have identified the coyote as The Trickster.  A trickster is a sort of cunning character who makes use of subterfuge, i.e., illusion, misdirection, etc., usually with the goal of committing some sort of fraud.  Accepting for the sake of discussion that it is valid to anthropomorphize wild animals, then to my eye, the suggestion that the coyote is a trickster is an apt judgement – they always seem to be up to something slightly sketchy.

This trickster nature is apparent in the way the coyote carries itself, which a bit shifty, moving through the sagebrush or tall grass like a pickpocket working the crowds at a carnival.  The short, persistent gait of the coyote is distinct from that of the wolf, which has longer legs and a resulting much more open stride. Parenthetically, although there are several ways to distinguish wolf and coyote, the difference in gait is the thing that I notice first.

And of course that Coyote face, which is so full of mischief…  Is it my imagination, or are these guys always squinting?

Perhaps it is their opportunistical feeding behavior that impresses me most.  Unlike wolves that hunt large prey in organized hierarchical groups, the coyote bounces around solo or in pairs, and will eat anything it can.  Voles seem to be a staple food of the coyote.  We have watched coyotes consume half a dozen voles in a single episode – in fact I cannot recall seeing coyotes eat anything but voles!

Leaving out the anthropomorphic judgements, there is no doubt but that the coyote is a highly adaptable and highly successful creature.  The Trickster even adapts relatively well to urbanization.  Although it is most common to observe coyotes hunting solo or in pairs, within Yellowstone, coyotes live in packs of up to seven individuals.

Prior to the reintroduction of wolves into Yellowstone in 1995, the coyote population grew to relatively large numbers due to the lack of a major predator.  In the years immediately following restoration of a stable wolf population, coyote numbers fell 30-50%, but the population has now stabilized.  The Yellowstone Resource and Issue 2011 report* does not provide a specific population esitmate for coyotes, and lists the population only as ‘numerous but unknown’.

Images in this entry were recorded in the Hayden Valley, Yellowstone National Park, at around 13:30 MDT on September 21, 2011, using the Nikon D7000 and the AF-S NIKKOR 200-400mm f/4G ED VR II  at 400mm (600 mm FX equivalent).  Exposures were made at f/5.6, f/7.0, and f/8.0 with shutters speeds at either 1/1000s or 1/1250s.  Tripod setup was the Gizto GT5541LS and the Wimberly WH-200 gimbel head.
