Beneath the Ledge II

For most of a year I’ve had a camera trap beneath an overhanging rock ledge. Some of the first photos were posted here.

Several checks of the camera trap since that post yielded more photos: an eastern chipmunk –

A porcupine that apparently dens in the labyrinth of overhangs, fallen slabs and crevasses of a nearby rock outcropping and from time to time appeared on camera –

As before, white-footed mice were frequently in the photographs, often climbing on the ledge –

When it rains, water drips from the overhang creating a wet spot on the upright slab. It was there that a white-footed mouse assumed a spread-eagle posture to drink from the wet spot –

Gray squirrels were common visitors –

There were several photos taken of a house cat far from “home” –

The house cat was fortunate to get that far from civilization without becoming a meal for a coyote or great horned owl. But it would be better for native wildlife, especially birds and small mammals, if the house cat had provided a meal for a predator.

The camera trap captured its second photo of a gray fox –

On September 1, for the first time, the camera caught a black bear beneath the ledge –

The bear became a regular visitor, appearing on camera again on September 29, October 12 and October 21 –

A bobcat lingered long enough for the camera to get a few photographs -
The most fascinating photos were the large number of photos (20+) of a camel cricket taken on several different days. The camera’s passive infra-red (PIR) sensor  reacts to changes in temperature to turn on the camera and trigger photographs. How sensitive the PIR must be to react to an invertebrate whose body temperature is close to, or the same as, that of its surroundings, but the PIR did –

Although the camera trap doesn’t get a lot of photos, the variety of wildlife at this spot warrants keeping it in place.

I just loved seeing the secret lives of all these animals caught by your camera. I wonder if the bear was checking out a cave for winter? The bobcat was my favourite ... I understand they are very shy and not often seen in the wild.

The bear almost certainly won't den there, this is merely a rock overhang. Every bear den I've visited was in a cavity with an opening just large enough to admit the bear -- although three times I've seen females "den" beneath fallen logs or piles of tree tops where they've successfully given birth and spent the winter with their cubs.
