It is said that crows have an artistic sense in decorating their nests, by choosing the materials based on colors too. Besides that, crows create their own tools that are useful in their everyday life.
In order to see exactly the creation behavior of these tools that crows make, some researchers from University of Exeter have developed and have mounted some video camera on the back of the crows, small and light enough to not disturb them.
The cameras have also a microSD card incorporated so that the date can be recovered easily if the camera falls. Check out the video below.
