Find Moose, Find Water

I’ve been reviewing images recorded over the past year, and adding keyword and captions using Photo Mechanic (stay tuned for a review).  In the process of reviewing images I noticed that without a single exception, in dozens of encounters with Moose, I always find them either in or very near water.

The images of the bull Moose were recorded at around 15:00 MDT on August 8, 2010 near Jackson Lake Lodge in Grand Teton National Park, using the Nikon D300 and the AF-S VR Zoom-NIKKOR 70-300mm f/4.5-5.6G IF-ED lens at 300mm (450mm effective).  Exposure was f/8 at 1/200s, ISO 400.  There were literally hundreds of people observing this Moose.

Moose are the second largest land animals – only Bison are larger – and bulls can grow to nearly 7 feet in height and weight over 700 lbs.  The Moose found in the western lower 48 states is the Shiras subspecies: Alces alces shirasi (A. a. shirasi).  Apparently, the salient behavior of the Moose is dominated by the dietary needs of the animal, which are, unsurprisingly, extraordinary.  Adult Moose need to consume around 10, 000 calories per day to maintain their body weight.  In addition, the need for sodium supplementation in their diet motivates them to engage in two characteristical behavioral traits.  First, as aquatic plants contain relatively high amounts of sodium, Moose seek out such plants and are thus often found in or near water.  Secondly, where natural sources of salt are unavailable, Moose will favor man-made sources of sodium, which largely consist of excess salt found near the edges of roadways.  The proximity of Moose and cars often to disastrous results for both the driver and animal alike (a recent car-Moose encounter in northern Utah is described here).

The images of the cow (above) and bull (below) were recorded at around 10:00 on September 23, 2010 near the bridge just east of the Moose Visitors Center, Grand Teton National Park, using the Nikon D3s and the AF-S VR Zoom-NIKKOR 200-400mm f/4G IF-ED lens at 400mm.  Exposure was f/8 and 1/1250s, ISO 1000.  As with the Moose we saw early in the year near Jackson Lake Lodge, there were were literally hundreds of people viewing these two animals.

    Cool sequence of shots. Can you help explain what is going on with the antler in the top picture. Notice the right side appears to be torn (the animals left side). Not sure if he picked up something in the water which is hanging, or he had some animal enounter. I heard that moose are in the road in alaska as the snow is so deep in the forest near the road. The road is easier for them to walk along. A team up there uses snow mobiles in high traffic area to compact the snow just off the road to reduce accidents.

    In the first shot there is a large bit of felt that is falling off that Moose’s antler. Yes, even the wildest of beasties will make use of roadways. In Yellowstone NP in spring, there are frequently traffic jams that are caused by small herds of Bison wandering down the middle of the road – this is especially a problem between the West Entrance and Madison, and throughout the Lamar Valley.

    Cheers,
