A sequence of images caught by a camera trap tells an amazing story!
Remote cameras can document wildlife behaviors seldom witnessed by biologists in the field. Such was the case last summer in the North Cascades of Washington, when a camera captured images of an unusual cougar-moose series. Check it out: woodlandparkzoo.exposure.co/life-on-camera
