Scientists trying to learn about the lifestyles of elusive critters (tigers and cougars come to mind) have their work cut out for them.

Many animals will smell or hear a researcher long before the researcher sees them. As for observing nocturnal animals? Forget it. But in the last few years, many wildlife researchers studying animals in their natural habitat have had a technological assist from camera traps. These devices lie in wait until a passing animal triggers their motion sensor.

Then, click! — a candid shot of a creature in the wild.
