Rainforest Creatures Caught on Camera
In the rainforests of Peru, scientists with the National Zoo's Monitoring and Assessment of Biodiversity Program set up cameras that "trap" wildlife in the area, digitally at least. When an animal walks by one of these traps, sensors register its body heat and movement, giving researchers a candid shot of nature. The photos are used to document rainforest biodiversity.
Below are three photographs that show the range of Peruvian wildlife. For 20 more images, check out the Zoo's Flickr Page.
