A collared peccary and her very young piglet get their photo taken as they pause for a rest in a remote area of northeastern Peru on August 18, 2008.
In addition to counting species and estimating population numbers, camera-trap photos provide scientists with unusual insights into animal behavior, such when different species reproduce.
For instance, scientists could estimate the age of the piglet in this photo and figure out when peccaries usually birth, Kolowski pointed out.
The zoo researcher hopes the Peruvian Amazon Biodiversity Project will allow "people to see the huge diversity of animals that live in the Amazon," as well as make the public aware of some of the threats, such as hunting and habitat loss, that exist for these rare creatures.
