Elk Living, Elk Dying

Making it to adulthood does not mean an easy life for an elk. Life in the wild is a constant test of fitness. Dodging disease, injury, predators and the like is a full time job. Oh, and then there is hunting season.

In the west wolves are returning and cougar populations are growing. The timberland that was once a refuge is now a potential trap. Pack wolves roam the open country looking for the any sign of weakness.

If an elk is lucky enough to make it to old age, then the winters become the true test. A harsh winter will kill many adults - usually the older ones.

Elk Predator

In NE Oregon, elk cows often return to the same birthing grounds year after year. Once they go into labor, they separate from the herd and seek quiet isolation. When the calf is born, it is not unusual for the cow to leave the calf unattended for small stretches of time.

Predators know this, and bears and cougars will often spend their time methodically searching for hidden elk calves – an easy meal. For such a large animal, elk calves can hide extremely well. I once spent hours searching for a calf that I spied with my binoculars bedding down at 75 yards. I had no luck.

Nonetheless, an arch predator like a mountain lion has far better senses than me. And they will find the easy kill. The calf below was found and killed by a cougar, and then covered for later feeding. The photo shows the cougar uncovering the calf. Note the scars on the face of the wild cat. Life has not been easy, and the calf was likely a rare break in the animal's hunting life – where it did not have to risk injury to secure food...

A Bull Elk Emerges From The Shadows

On a miserable, rainy night along the coast one of my remote cameras photographed a spike bull roosevelt elk (Cervus canadensis roosevelti) walking along a muddy elk trail.

One of the reasons I use remote cameras is because they allow me to take photographs where no sane photographer could possibly pull it off. I had the cameras in place for six days before these photographs were taken. The nights were frigid and dark, and yet the cameras waited patiently.

Water on the lens makes this elk appear as if it is emerging from the ghostly shadows of a nocturnal forest (above).

I pulled the cameras after they were in place for 10 days, primarily because of a massive series of storms moving in from the Pacific. The weather had already been bad, and I had experienced several technical problems, and near destruction caused by water in the past.

My remote camera system has new waterproof connectors, and better weather housing, but I wasn't quite ready to leave it in the flood plain of a small creek.

In one image, the elk passed extremely close to a camera placed very low.

Just inches from the muddy ground, the camera lens received a coating of muck.
