Almost Invisible

Hares do not live in burrows. Instead, during the daytime they nestle in the vegetation or scratch out a shallow indentation in the open ground called a form in which they crouch down with their ears flattered against their back and become almost invisible. Rough ploughed or cultivated ground is a natural choice for hiding in. These forms may be used on a regular basis and can become worn smooth.
