In the past researchers had to capture and tag an animal to track its movement and habits, however, with the possibilities of a new biometric solution, the animals may never have to be tagged again, according to a BBC News article.
The new solution, currently being implemented on tracking a large group of African penguins, involves using stationary cameras in high traffic areas to track individual animals by unique markings; in the penguin’s case black spots on their white bellies.
The researchers are hoping to expand the new system in the future by utilizing zooming and panning cameras as well as trying the system out on other animals with distinct markings.
Tagging animals in the past has thought to have possible negative affects on the animals due to wear in the areas of the tags. Additionally, it was tiresome for researchers as it required capturing an animal twice, once to tag and again later to record data.
By implementing this new system some believe they may be able to end any injury that has come to animals through past tracking measures, as well as creating a more reliable and cheaper alternative.
